Do I have to unplug my microwave oven?

Common user mistakes

Mistakes when operating a microwave oven

Some users decide that the microwave oven can do everything and start experimenting, and then pay for repairs or buy new equipment. To prevent this from happening to you, don’t make simple mistakes while using your microwave:

  • Do not dry things in it.
  • Do not start heating food if you see that the glass is not spinning properly. Chances are your dinner will start to burn.
  • Do not run an empty microwave oven.
  • Do not put metal or painted objects in it.
  • Don’t use the defrost, microwave grill, or other function longer than the instructions say.
  • Don’t cook with a lot of fat or oil, don’t boil eggs.
  • Don’t try to start a broken oven.
  • Don’t heat food without a hood.
  • Do not wash with rough sponges or detergents.

Microwave ovens

Today, most of us have a microwave oven, as the microwave oven, or microwave oven (microwave oven) is commonly called, in our kitchen. It is usually used as a supplement to a traditional electric or gas stove. Yet despite the popularity of microwave cooking, there are many safety concerns. Understanding how a microwave oven works and what protections are built into it should dispel any doubts.

The main danger is not from microwave (microwave) leakage, which is very rare, but from the very high voltage generated in the instrument. Therefore, all internal service and repair work must be carried out by specialists. In this regard, this article is not intended to recommend or encourage self-repair of microwave ovens.

How it works

A large transformer increases the standard 220-230 volt voltage tenfold, and at this voltage the current is fed to a high voltage capacitor, which retains its charge even when the appliance is turned off and its plug is removed from the socket. A transformer and capacitor power an electronic device called a magnetron that converts electricity into high-power radio waves. These waves are a form of electromagnetic energy that is directed into the working chamber through the magnetron antenna.

In a manner similar to the way a magnet affects the compass needle, microwaves in the cooking chamber orient the atoms that make up the food, changing their direction from north to south about 2450 million times per second (2450 MHz). The resulting “internal” friction creates energy in the form of heat that cooks the food to a depth of about 2.5 cm. With greater thickness, convective heat transfer conducts heat even deeper. Therefore, in order to ensure that the food is cooked completely, it must stand for a while after the microwave oven is turned off.

  • Rotating cooking tray
  • Rotating antenna
  • Rotating impeller with metal blades that reflect microwaves and make them move around the oven in different directions.

Combi ovens

Combination microwave oven combines the best qualities of traditional and microwave cooking. Defrosting and cooking at a certain temperature is faster and more efficient when using microwave energy, but the food is more appealing when using heating elements such as TEN and convection. Depending on the design, a combination microwave may have a grill, fan (which provides convection) and even a toaster.

COOKING TIME

Choosing the right power output (high, medium, low or defrost) and the optimum cooking time.The key to successful microwave cooking. The exact combination of power and time is always indicated in recipes and is usually found on the packaging of frozen foods.

Keep in mind that food continues to cook for some time after the microwave oven is turned off. Usually the recommended cooking times are also indicated in recipes and on packages.

The power emitted by the magnetron differs depending on the model. It is indicated in watts and is usually found on the rating plate and in the user manual. The power output is proportional to the voltage supplied to the oven; therefore, an oven with a power rating of 700 W will only achieve this at 230 V.

Microwave

Some are afraid of microwave radiation (ultrahigh frequency radiation).microwave) when standing near the microwave when it is operating. If all covers and panels are in place and the appliance is in good condition, there should be no harmful radiation. and microwaves simply can’t pass through the vents.

However, if you have concerns about your oven, it can be tested for radiation leakage. And after repair, any competent technician will check this appliance for radiation with a special calibrated instrument. These instruments are expensive and therefore not usually found in a home tool kit. However, it is possible to purchase a reasonably priced microwave detector, or probe, that is designed to indicate dangerous levels of electromagnetic radiation.

To check for radiation leakage, put a cup of water in the microwave and turn on the oven. With the tip of the detector touching the body of the microwave, move the probe evenly along the door jamb. Run the detector through the door as well. Diagonally between all four corners. Check the control panel and vents, too.

If radiation is noted or even if it is only suspected, make sure the inside surface and door edges are completely clean and test again.

If the detector registers radiation again, turn off the microwave, unplug it so that no one uses it, and contact an appropriate repair shop. Do not try to service or repair it yourself.

Microwave oven cleaning

In addition to hygiene considerations, an oven that is cleaned regularly is less likely to break down. A dirty door may not close properly, which will either cause the appliance to lock on or.Even worse. To exposure to ultrahigh frequencies. Be sure to unplug the microwave oven before cleaning it.

Some combination microwave ovens are self-cleaning (check your owner’s manual).

Cleaning the inside

Some models have a removable bottom interior panel of the oven and can leak liquid into the cavity underneath the panel. If this is not noticed in time, the appliance could be damaged.

MAKE THE MOST EFFICIENT USE OF YOUR MICROWAVE

  • Use the appropriate cooking mode for each food item.
  • Always clean the oven regularly.
  • Avoid splashes. Close microwave containers with their own lid. Alternatively, cover them with a paper towel.
  • If your microwave doesn’t have a removable glass rotating tray or stand, place the container on a paper towel to keep the bottom of the oven from getting dirty.

Steam the oven cavity

To remove hard deposits, fill a small container designed for microwaves with water and place it in the center of the oven. Turn on full power for a few minutes. but make sure that the water does not boil away. The steam should soften the deposits and then they can be removed with a cloth.

Cleaning the door

Do not allow crumbs or food particles to accumulate on the edge or inside surface of the door. Wipe both of these surfaces regularly with a slightly damp cloth.

Cleaning outside

The outer surfaces of the microwave can be cleaned with a slightly damp cloth or sponge. Do not allow liquids to enter the ventilation holes or behind panels and covers.

Cleaning the Control Panel

Use a slightly damp cloth to clean the touch control panel. Do not really wet the control panel, as moisture can get inside and then the oven must not be switched on again until it is completely dry. and it may even be necessary to replace the control panel.

Microwave oven repair

First things first

  • Whether the plug is plugged in? Is there power in the socket??
  • Is the door well closed??
  • Are the timer and power set correctly?
  • The clock is set correctly?
  • The microwave oven is not dirty?

UNPLEASANT ODORS IN THE MICROWAVE

Spicy food

There may be odors left in the oven cavity after cooking certain foods. If normal cleaning doesn’t solve the problem, try the following.

Mix 1 part lemon juice with 3 parts water in a microwave container. Put the container in the microwave, put it on high power and let the juice and water boil for 3-4 minutes. Let the container with its contents cool down, then take it out and wipe the oven dry with a paper towel.

TURNTABLE DOES NOT ROTATE

Tray is not connected to the drive

Remove and reinsert the drip tray (and roller cage if your model has one) and try the microwave again.

Damaged drive

The drive nozzle on the rotating tray motor shaft is made of plastic and protrudes from the bottom of the oven. Check if the nozzle is tight enough on the motor shaft. If not and it comes off easily, buy and install a replacement.

Faulty rotating tray motor

Rotating pan is driven by a small electric motor and gearbox. If the motor has failed, the tray will not turn, even if there is nothing wrong with the wire. Have a qualified technician check and replace the faulty motor.

NO OVEN LIGHT

Lamp has blown out

If the microwave is operating normally, the interior light should come on when the door is opened and/or during cooking. If it looks like the bulb has burned out, do not try to replace it yourself. It should be done by a service technician. While you are waiting for the lamp to be replaced, the microwave is safe to use.

MICROWAVE SPARKING

There is foil or metal objects in the microwave

Foil or metal objects in the oven cavity reflect microwave electromagnetic energy, causing sparks.to an electrical discharge called an “arc discharge”. Sparking can shorten the life of the magnetron. Do not use metal cookware (except as recommended), wire wrappers, metal skewers, or ceramic cookware with a “gilded” pattern or border.

To prevent food from burning, some recipes recommend wrapping foil around sensitive parts of the food.such as fish tails or chicken feet. However, under no circumstances should you place food completely wrapped in foil in the microwave. See your microwave’s owner’s manual or a good microwave cookbook for details.

Build up of crumbs

Clean the microwave thoroughly and regularly. see. previous page.

VAPOR LEAKAGE

Normal Ventilation

Air sent to the magnetron for cooling enters the oven cavity and escapes through the ventilation holes in the back of the microwave. This air traps the steam produced during cooking. Therefore, steam coming out of the vents and sometimes around the door. is a very natural phenomenon. As it cools, steam may condense on the inner surface of the door glass, which is also normal.

THE FOOD IS NOT COOKED PROPERLY

Wrong timer setting

Check the weight and type of food you are cooking and adjust the timer settings accordingly if necessary. Do not forget the holding times for finishing cooking.

Frozen food

Did you remember to set a longer cooking time for frozen foods?

Wrong power setting

Check what power should be used to cook this product.

Faulty magnetron or internal wiring

If you notice that it consistently takes significantly longer to get the desired results, perform the following test to make sure that the oven’s actual power matches its stated power rating. see. page. 165. If the test shows that the unit does not develop the rated power, then either the magnetron or the internal wiring may be defective.

  • Label the containers with letters A and B so that you can distinguish them easily and pour 500 ml of water into each. Stir the water and measure the temperature: it should be about 15°C. If the temperature exceeds 20 °C, the results may not be reliable. Record the temperature in each container and label it as T1 (starting temperature).
  • Subtract T1 from T2 for both containers and calculate the average temperature increase for the two containers. Then multiply this average value in degrees Celsius by 50 (this is the frequency of the current in the household electrical system). The result gives the power of the magnetron in watts.

Check this value against the microwave power rating indicated in the owner’s manual or on the rating plate.

A difference of plus or minus 10% is acceptable, but if the test results are much less than the rated power, there may be an internal fault in the appliance. If your microwave oven does not meet the specifications, clean and dry it and then recheck. If the results are still too low, contact a qualified technician to check the microwave. Do not use it until the cause is determined and corrected.

Examples of tests

An example of a 650 W microwave oven test might look like this:

Container A
Т1 Т2
15 °С 27 °С

The temperature increase (T2 minus T1) for container A is 12°C and for container B, respectively, 14°C. The average value of the temperature increase will therefore be:

The output is calculated by multiplying the average temperature increase by 50:

Low voltage

This is rarely the case. But if you use several powerful appliances at the same time as the microwave, the voltage can drop, which will affect the microwave’s power as well. The solution is to use fewer appliances when cooking in the microwave.

FOOD IS OVERCOOKED

Incorrect timer setting

Check the weight and type of food being cooked and adjust the timer setting accordingly if necessary.

unplug, microwave, oven

Wrong power setting

Check what power should be used for this product.

Vents are blocked

Make sure the ventilation openings are not clogged or obstructed. Allow enough space between the microwave body and the walls for ventilation.

Condensation

Problems can occur if the microwave is placed too close to an open cooking area where steam from the kettle or pots can penetrate behind the touch panel.

If the microwave will work fine after it has dried completely naturally, try moving it to a place in the kitchen where it is less likely to be exposed to high humidity. If the defect persists, consult a qualified technician.

MICROWAVE OVEN DOES NOT TURN ON

The plug is not in the socket

Check that the plug is inserted into the socket and that there is voltage in the socket.

Defective fuse

Remove the plug cover and check that the wires are properly connected. If in doubt, replace the plug.

Check and if necessary replace the tube fuse.

There is no power supply

If other appliances in the same circuit have stopped working, check the fuse box for a blown fuse, tripped circuit breaker or RCD.

Installing the clock

unplug, microwave, oven

Does the display light up?? If so, check that the clock is set correctly. Some models won’t turn on if the clock is set incorrectly. This problem often occurs after the mains power supply has been cut.

The door isn’t closed properly

Microwave Ovens Safety: Do’s & Don’ts

Open and close the door a few times to check if the latch works properly mechanically. If that doesn’t solve the problem, you may have to replace the latch. Consult a service center.

Internal Fuse

Microwave ovens are equipped with internal safety fuses that can trip for a number of reasons. Contact service to check internal fuses.

Faulty timer or switch

Only a qualified technician can check and repair such malfunctions.

MICROWAVE OVEN CAVITY FIRE

Overheating of the food

In the unlikely event of a microwave chamber fire, unplug the oven and remove the plug from the outlet. Do not open the door and allow the fire to burn.

In some models, turning off the appliance with its own switch automatically opens the door, so if this type of accident occurs, you should only unplug the microwave from the outlet.

Have the oven checked by a service technician before continuing to use it.

TV OR RADIO INTERFERENCE

If the TV or radio in the kitchen gets interference when the microwave is on, try putting the receiver further away from the microwave. If the interference persists, it may be caused by the following.

Faulty mains or surge protector

This type of fault can only be determined and repaired by a service technician.

No grounding

This is a serious problem. Pull the plug out of the socket and check the grounding with a tester. Also use an outlet tester to check the grounding in the outlet.

If the tester shows a fault in any of these cases, do not use the microwave or the outlet until the cause has been determined and corrected by a service technician.

My husband constantly unplugged the kettle and microwave. It pisses me off.

You heated something. Pulled the plug, wanted to heat something up again. Put it back in. I can’t take it anymore. You see, that’s how they used to do it at home. We’ve been living together for almost 4 months. I begged him not to do that!! Today I kept it, I was just frantic. I pressed the button on the kettle, went to the bathroom. I’m out. he, of course. cold, because once again I forgot that it must be plugged in. In short, in anger shattered the kettle into small pieces, and one and a microwave, I just shook all. Of course, I feel that now I will be full of attacks, but at least I spoke out.

And rightly so: the elementary rules of safety. Before leaving the house for a long time, it (turn off) at all necessary. You’d better not be so hysterical.

I have a friend like that, it was also common. and the kettle, and the microwave, and the TV. They were afraid the outlets would pop, or there’d be a fire

In short, in anger shattered this kettle in little pieces, and one and the same with the microwave, I was shaking all over.

Husband needs to pin domestic violence on you and divorce you. Hysterical.

Wouldn’t it have been easier to tape the plug to the socket so he couldn’t pull it out??

How does it live in the same house as the refrigerator?? You can’t pull it out.

If there are normal gas stations in the apartment, then there is no special point in pulling out the kettles, unless you go on vacation, of course.

And you can also shut off the water after every hand washing. Just in case.

And rightly so: it’s elementary safety rules. Before leaving home for a long time it (turn off) is generally necessary. You should be less hysterical.

Nonsense, at most the fuse will blow. And turn off the fridge, too?

That’s what we do as a family.I’m telling you, whoever doesn’t do it gets a reprimand.It’s really elementary safety precautions.You have to take it easy or it wouldn’t hurt to get in the habit of doing it yourself.Take a sedative, such little things should not lead to hysteria.The problem isn’t the outlets.

That’s what I mean!! He turns it off even when we’re at home

No, author, you’re not hysterical.A little unstable, you can’t handle the situation, but no more. You have been living together for 4 months, which means that it’s been a very long period. Who. I suggest you be a little wiser and retrain yourself to pull the plug out of the socket. Or find the right words, in a SAFE tone to explain to your loved one that it is not necessary, it is inconvenient, it annoys you. Make a compromise. This is just the beginning, by the looks of it. There’s a lot of things about him that will irritate you further.

maybe even turn off the breaker before leaving for safety and drain the water from the batteries?

I turn it off when I go away for a long time, why are you all mad at the author. She’s not crazy, her husband’s paranoid. it needs treatment

Nonsense, the fuse will blow at most. Do you also turn off the fridge??

The refrigerator is originally designed (designed for) the constant operation of 24/7. And the microwave. No. Completely different things.

I only turn it off when I’m away for a long time, why are you all mad at the author? she’s not the crazy one, her husband is the paranoid one. he needs therapy

I totally agree! I can imagine the author’s rage, got out of the shower, got some tea to pour and taaaay bummer)))) maybe I’m hysterical too, but it would piss me off)

The refrigerator was originally designed to run 24/7 all the time. And the microwave. no. Completely different things.

Of course not. That’s why microwaves (except for mechanical ones) have clocks. They’re made specifically for amateurs who like to set them up every time they need to heat something up. Otherwise, what are they made for?? It’s not just for the sake of it.

I’d be pissed, too. The equipment may not have cracked, but it’s really unnerving. After my husband was tired of waiting for me when I leave the house while I run around for 10 times to check whether I turned off the stove, the iron, he just redid the wiring when repairing so that the input can turn off all the outlets in the house separately toggle switches. Only the refrigerator/microwave, TV and player outlets computers (these never turn off at all) are left on, the rest of the strategic things are simply cut off. I’ve stopped fidgeting and my nerves have calmed down.

I only turn it off when I’m away for a long time. Why are you all snapping at the author? She’s not the crazy one. Her husband’s the paranoid one. He needs treatment

I totally agree! I can imagine the author’s fury, she came out of the shower, pouring tea and such a bummer)))) I may be hysterical too, but it would piss me off)

That’s hysterical. I had a friend, so he was paranoid about washing his hands, every half hour he washed his hands with soap, he saw bacteria everywhere, he constantly told me not to eat with dirty hands. Don’t touch this, don’t touch that.When he drove me to the boiling point, fought to the ground, no longer communicate, which is insanely happy

dear author, I suggest you once again calmly talk and identify a few options for solving the problem: take out of the list moving away or buying another kettle and a microwave oven (only yours:)) and leave the last one, which I would choose: everything to ask her husband to do.those constant “reheat”, “boil me. “, “make me a cup of tea, honey, while I’m in the shower” and.т.д. If you hear one day, “What can’t you do?? I don’t want to run into an appliance and put you at risk, besides, I’m so glad you’re paying attention.

Why don’t you use a regular non-electric kettle in that case?? and put up with the microwave. You have to compromise. Or another option. get two kettles. his and yours :))))

I sometimes pull out the washing machine is also stressful:) although it may be right.Advice to the author-tape the plugs to the outlets or stick notes on the plugs-DON’T pull them out!

What to do? I’m afraid to leave

My grandmother calls me ugly

put stickers/letterheads near the socket “do not turn it off”)))

Mine doesn’t turn it off, but I have every urge to do it. Right now she’s just taking the kettle off the tray of this, I don’t know what it’s called. At first it pissed me off, but now it’s calmed down. But what I can not reconcile with is that it is necessary to leave the room for a couple of minutes, when you return everything is off: light, TV, iron. Provided, of course, that he himself at this time in another room. I turn off the light when he’s in the bathroom

Actually, my husband’s right. All that radiation.computer, microwave, kettle TV, refrigerator. if possible, of course all is better to turn off (of the three evils can leave the refrigerator. no way without it).

And here pounding household appliances. Not good. That’s okay. kettle on the stove boil, food from the microwave is worse than from the stove, so)))))) no kettle. No problem.

I’ve never understood why you have to break dishes in a scandal. and the dishes. if you’re so uptight, go bang your head against the wall)))) there’s less damage to the budget)))) and if you don’t have a brain. no damage at all)))

I sometimes pull out the washing machine is also stressful:) although it may be right.Advice to the author-tape the plugs to the sockets or glue notes on the plugs, NOT TO REMOVE!

Why does he turn it off, is he sick or what?? I would also be sick of it.

29,It turns out everything must be turned on and off a hundred times a day, the kettle, microwave, TV, refrigerator, computer, etc.п.You can go crazy that way.I support the author.I would also smash the kettle against my husband and pinch his head in the microwave.

The refrigerator was originally designed to run 24/7 all the time. And the microwave. no. Completely different things.

Of course not. That’s why microwaves (except for mechanical ones) have a clock. They are made especially for amateurs who like to adjust it every time they need to heat something up. Otherwise, what are they made for? It’s not just for “shoba” reasons.

About the clock on the microwave, I forgot, I’m used to it all the time 0:0

All these radiations.computer, microwave, kettle TV, refrigerator. )

what’s your husband’s reasoning?? They used to turn it off so they wouldn’t burn out from overvoltage (when TVs cost as much as planes). That kind of problem is rare now. If he is so afraid that the appliances will burn out. buy a UPS. he will 100% protect against it.

I think I recognize my fiancé’s real face, it hurts

The former will be back, or how do you evaluate this situation in general?

Aurevoir!)))) I was wondering about the radiation, too. Enlighten.

It was not easier to tape the plug to the socket, so he could not pull it?

Already ordered, new microwave, tomorrow I guess I will do so))))))

Also he always opens the curtains, they may have to be nailed to the wall)))

Mine does not turn it off, but I have every incentive to do so. Now he just takes the kettle off the tray, I don’t know what it’s called. It pissed me off at first, but now I’ve calmed down. But what I can not reconcile with is the fact that it is necessary to leave the room for a couple of minutes, when you return, everything is off: light, TV, iron. Provided, of course, that he himself is in another room at the same time. I now turn off the light when he’s in the toilet

no sooner go to the toilet and close there than immediately the light in the room is turned off, the TV and the laptop is closed)))) as well as all possible pilots are turned off))))))))

Yes there are no arguments, it was just the custom at home))))

Man, that would piss me off too. my husband is full of shit

Aurevoir!)))), I also wonder about the radiation. Enlighten.

I’ve heard a couple of times that everything plugged in emits some kind of waves and has a negative effect on health.

Yes there is no argument, it’s just that it was customary at his home)))))

My husband, on the contrary, in his family was not supposed to turn anything off, because they were convinced that if you often turn off the equipment, it will quickly break down.That’s why everything is on at home now

people, why are you so clueless and demanding arguments? Fret

It’s a habit, you know? Instinctively! It’s automatic, you don’t think about it

Aurevoir!)))), I wonder about the radiation too. Enlighten.

There’s no radiation at all. You’re all full of crap.

GuestDa there are no arguments, just at his home so was accepted)))) At my husband, on the contrary, in the family was accepted not to turn off anything, because they were sure if technology is turned off often, it quickly breaks down.That’s why everything is on at home now

Well, the computer just can not constantly turn on and off. About the rest, I do not know))

About the broken kettle and the microwave: it’s already “ringing”, the author. On the problem of switching off: great advice gave, to ask your sweetheart ALWAYS turn on and off, but even better (I think) pull the cord, not holding the outlet. In a couple of days the socket will fly out, as if whole, and let the husband goes and screw in all the outlets, day after day.

PS^ I’m actually for compromise with my beloved half, otherwise you can go too far.

I lost three men because of my inability to use chopsticks. Shame on you.

Should appliances be unplugged??

When you leave home, you unplug the kettle? Pull the plugs out of all electrical appliances? Or vice versa. you don’t unplug anything and never even planned to do it? In this article we’ll dot all the “i “s and understand once and for all, if it makes sense to unplug appliances.

Do you have to turn appliances off when you leave home??

Do you have to unplug electrical appliances when you’re not using them?? Or you leave home altogether? Do they consume extra electricity in standby mode and pose a fire hazard?? Many viewers ask about this in their letters, and we decided to find out from the experts.

Muscovite Alsu Safikhanova never leaves her microwave, kettle, TV, washing machine and chargers unattended. Even the refrigerator unplugged when he goes on vacation. And all because not once but three times she had unpleasant incidents that could end badly.

In general, the equipment itself, as a rule, is well protected from such problems. The head of the testing laboratory Alexander Pestryakov shows that a piece of the teapot stand, where the electric contact is, can withstand the heat up to 650 degrees. This is required by GOST. Plastic melts, but does not ignite. That is even if in case of breakage the contact will be strongly heated, the kettle must not catch fire, which requires a temperature of not less than 750 degrees. What is unrealistic in standby mode. And this applies to any legally manufactured and sold household appliances.

But here are the extensions, doublers, tees. this is a weak point. Alexander says that many people test their strength by regularly giving them a completely inadequate load.

If you turn on three devices at once, the cable simply heats up, and smoke comes out of it. it seems, and it should be clear to everyone, but experts say that the load is very often incorrectly calculated, even by electricians who make home repairs. And it’s important to realize that if you regularly force the wire to get even a little hot, it can then spark and from a small current. When we cut the cable, we could see that the insulation inside was melted, one step away from a short circuit! Leaving it in the socket under voltage is dangerous. it can start leaking current and uncontrolled heating. Even though the technique itself, when not working, creates a negligible load and consumes very little electricity. We checked the consumption of microwave ovens, TVs, laptops, oil heaters, heaters, coffee makers, kettles, multivolators, extension cords, and phone chargers. For this we had to find a very sensitive device.

The consumption was very small, tiny even. Power consumption in standby mode for chargers. some hundredths of a watt, a laptop. three tenths, that is, in the money is not more than a few pennies a day. The same order of numbers for a TV (1.2 watts). The thermopot consumed the most, of course, on the order of 7-8 watts, in standby mode it heats water. The coffee machine also has this function, but it uses only three-tenths of a watt. But the kettle and the heater had mechanical switches, and even connected to the socket, they did not use electricity at all.

In general, our conclusions are as follows. It is still possible to leave modern appliances in standby mode. But at the same time it must be in working order, and it is necessary to wipe off dust on the back wall of the fridge at least once a year, letting the extra heat escape. To protect yourself from fires, it is important to monitor whether there is an excessive load on the sockets, tees, extension cords, wiring in general. Surge or short-circuit protection systems can help, too. Enjoying the comfort, do not forget about the reasonable precautions.

How to prolong the life of the microwave oven

Using your microwave oven according to the rules, you can noticeably extend its life. A good oven can serve without malfunction for five years or even more. If the furnace is in good working order:

Important! Remember, furnace failures are also dangerous to the owner. If there are any malfunctions, take the microwave to a service center immediately.

The oven’s longevity depends on proper usage: use proper utensils and cook according to the manufacturer’s recommendations.

To avoid disappointment during the first use, it is important to follow the manufacturer’s advice. Do not:

  • Turn the oven on when the cavity is empty;
  • turn on the appliance when the weight of the food is less than 50 gr;
  • Use metal ovenware;
  • exceed a reasonable cooking time. risk of fire;
  • wiping the protective screen. a plate of mica (it is located in the chamber, usually on the side wall) with force;
  • Switch it on if there are any obvious defects: cracked glass, poorly closed door, etc.д.;
  • Heat or boil eggs;
  • Load into the chamber tightly closed containers and jars with food.

Useful tips

  • Before you start the grill, put a cup of water inside.
  • Close the door firmly.
  • If you are going to heat foods wrapped in a vacuum or skin, pierce them with a sharp object in several places before turning on the oven.
  • In order to keep the cavity clean and to avoid having to wash it every time after cooking, you must cover the food with the lid. Grease and food splashes can cause the mica-shield to fail prematurely.
  • Do not leave the appliance unattended.
  • Don’t handle dishes right after you turn the oven off, you’ll get steam burns.
  • Use a soft sponge to remove food debris from the oven.

The average lifespan of a microwave oven is five years. By following the manufacturers’ recommendations, it can be doubled.

Electricity thieves: 8 appliances that stealthily screw up the meter

The first and most notorious thief is the television set. When you turn off the TV with the remote control, you’re only putting it to sleep, not turning it off. In this state, the TV consumes about 25 watts a day, or around 750 watts a month. If there are several TVs in the house. multiply the amount by their number.

Do not turn on an empty microwave oven. You categorically shouldn’t do this, but some furnace owners allow their children to play with the device. There are those who think the oven will dry out faster after cleaning. This is due to the structure of the microwave oven: the main part in it generates electromagnetic waves that affect water molecules. Water molecules give off heat to tissues, products. Accordingly, if the microwave oven is empty and the generator is running, the energy inside the chamber increases and it needs to go somewhere. The mica plate that protects the generator starts to burn, the plastic parts inside the chamber melt, etc. д.

Do not reheat foods with low water content. For the previous reason, you can’t heat foods like dried fruit, nuts, sunflower seeds, breadcrumbs in a microwave oven. Could potentially cause damage.

Do not sterilize empty jars in the microwave oven. Same reason.

Do not put metalized cookware in the oven. We’re talking about what’s called a saucer with a rim. Someone is wrapping food in foil. Metal is a conductor. discharge occurs between the foil and the oven walls.

Do not cook eggs in the microwave oven. It is less common, but, for example, before Easter it is a practice. Eggs are more likely to explode.

Do not look into the door of a working microwave oven by moving in close. There may be a microscopic electromagnetic wave leakage in the gap in the door. This is a reassurance for those who are afraid of something.

Be careful with microwave oven cleaning and water. There have been cases where the stove has been washed in the bathtub under the shower. But there are technological holes in this appliance for steam exhaust, a fan, etc. д. A lot of water got inside, many parts burned out. If water gets down, it can burn out the motor that turns the plate. If it gets in from above, it can get into the control board. The front panel is often washed with water, too. And it does not matter if it is a button or a sensor. Water gets inside, contact wires get destroyed and then the oven doesn’t respond to buttons. If these are not popular brands, there are often no spare parts. Such an oven will have to be scrapped. But even if it’s a popular brand, parts are often discontinued, and you can no longer find the original parts for them on sale.

Do not clean the oven with aggressive grease removers. Another very common breakdown is the destruction of the mica plate that protects the generator. It cannot be cleaned with aggressive grease removers. Nothing will happen to the chamber, but the mica plate will split and fall apart. Meanwhile, it is quite easy to repair, if you do not start the situation.

What you shouldn’t do to your microwave at all?

It’s already clear how a microwave works, but for many people it’s still not clear why you can’t heat anything containing metal in it:

  • Ironware;
  • cups and plates with a golden pattern;
  • cutlery;
  • canned foods;
  • foil-wrapped snacks, etc. д.

The fact is that the waves that the magnetron creates, when they hit metal in an enclosed space, contribute to the formation of electrical energy. As a result, sparks and electric arcs appear in the chamber of the microwave, and this can provoke a fire of the device.
