The microwave does not warm the causes. The microwave does not heat the food - a list of possible causes. Firms and quality: the microwave works, but does not heat

Microwave ovens are an integral part of any kitchen. The ability to quickly heat up or even prepare a dish is simply necessary with the present frantic pace of life. But, like any household appliance, a microwave can fail. And the symptom of one of the most frequent breakdowns in the appliance is the continued rotation of the dish, with inactive heating elements. Simply put, it still works, but does not warm it. What to do in this situation?

In The Truth About Cancer: A Global Quest, you'll find the most powerful ways to prevent, cure, heal, and beat the disease. For several days, he developed very debilitating symptoms when using his phone, computer, and all types of electromagnetic devices in his home and workplace. When his doctors and the medical community made a complete gap, Lloyd decided to find his own solutions. Lloyd has now made his life mission to raise awareness of the dangers of electromagnetic fields and to share the wonderful discoveries he made in his quest to restore his health.

Problem description and possible causes

This problem is common, and there may be several reasons for it. The fact is that the rotation of the pallet with the product, light and other signs of work are independent of the "insides" of the microwave oven. It turns out that some of the equipment may fail, but the furnace will function correctly. Here are the main causes of these symptoms:

McGee explained that my observations were “correct, not no”; The bottom line is that heat is heat, and regardless of whether it is produced by a gas flame or an electromagnetic wave, it behaves the same. However, my nuclear food could really cool faster for three reasons.

In the case of something like frozen pizza, the culprit is the container. A metal baking tray or pizza pan heated in the oven will absorb heat from the oven and become much hotter than the pizza sitting on it, helping to cook the pizza in the oven and keep it warm when it is sitting on the microwave in containers we use They are not directly heated by microwaves. Microwaves heat food, which, in turn, heats the container in which it sits, but never makes it hotter than the food itself. pizza leaves the microwave, it does not use the same heat source as in the oven.

blown fuse - if the fuse is blown, then it needs to be replaced. Usually there are several of them in a microwave oven, but one blown fuse is enough to cause malfunctioning of the oven. Fortunately, they are cheap. But do not approach the replacement of the fuse after a sleeve. They protect your kitchen from fire in case of power surges;
if you hear extraneous noise when the microwave oven is in operation, resembling crackles, then most likely it is a matter of the condenser. You can check it with a simple ohmmeter, before this, of course, you must turn off the device from the network and get rid of the voltage;
a magnetron is a more costly breakdown for you. The main symptom will be increased hum when trying to work the stove;
diode failure - they are easier to replace than to check, so it’s better to think of them last.

By itself, this failure is very unpleasant. After all, the microwave oven stops working as it should, but only creates an appearance. In addition, if the case was in the closure, the situation can only worsen with further attempts to use.

To avoid this, transfer the food from the microwave directly to the heated surface. For thick foods, such as, say, the remaining chilli or a portable platform for Thais, the problem here is uneven heating. Microwaves heat food unevenly in part due to different amounts of energy in different parts of the device. This often leaves the center of the food cold, while the edges are hot. Therefore, as soon as my microwave food remained sitting for a few minutes, the heat from the edges will be migrated to warm up the center, for the overall temperature of the cooler.

If the food is heated too slowly or it does not heat up at all - this is a sure sign of the furnace breaking.

In addition to these reasons, there are a number of things that should be checked before repair:

problems with the mains voltage - in case your network produces less than the standard voltage, there will be problems with heating the food. The smallest changes may entail unpleasant consequences in the operation of the microwave;
the power grid is overloaded - when a large number of devices are operating from one network, the voltage may not be enough for everything. As a result, your food will also not be warmed up normally, although the microwave oven will work;
problems with door latches - if the microwave door does not close the door tightly, then the food will not be heated effectively. This problem is easy to detect - it is enough to check if the door shifts during operation when exposed to it;
choosing the wrong oven mode - accidental switching of the microwave oven to low-power modes can cause confusion during further attempts to heat the food. Just check the settings that are used when warming up.

If you are sure that the failure is still present, it is worthwhile to proceed with its detection and repair.

Avoid this problem by stirring your food halfway through the heating process, or if it is something unruffled, move it to another part of the microwave through cooking. Advertising - Continue reading below. When it comes to coffee and other liquids, it is enough to circulate the liquid so that uneven heating does not occur. Even if it is heated to the same temperature as a full cup, a semi-prepared cup will always cool faster due to a proportionally larger surface area through which heat can flow.

Microwave Detection

Find out what of the reasons listed is not so difficult. Just follow these steps for detailed verification:

Repair actions

The microwave oven allows not so much action in the self-repair. Do not proceed to repair if you are not confident in yourself, and check every detail for the presence of a charge before touching it with your hands. This is especially true of the capacitor and the magnetron - they will need to be de-energized. Even if you probably determined the cause of the breakdown, in almost any case, you can only replace the broken part and nothing more:

This applies to any small piece of food: smaller pieces due to their higher surface area to volume ratio. There’s nothing to do about it, besides, drink your coffee faster and cut yourself more cake next time. Troubleshooting a microwave oven that lights up but does not work includes troubleshooting some of the most common technical issues. By eliminating problems at home, you save time and money by installing the device yourself.

Unofficial visits by technicians are often expensive, especially if the problem is simple enough so that it can be fixed at home. The most common problems that cause these symptoms are easily fixed without special tools or experience.

As you can see, the repair of parts itself is practically not performed independently. Personally, you can either identify the broken object and replace it, or immediately call the wizard. Of course, the master will tell you exactly what has broken and will perform a replacement if necessary. Do not attempt to repair the magnetron and other parts yourself. It is almost impossible and can only aggravate the breakdown.

Inspect your microwave for problems. Re-enter your cooking instructions, taking care to cancel any delays, enter the weight for the food if necessary, and click the “Start” button when you are ready to start. Skipping any of these steps may prevent the furnace from starting. Always ensure that the door is completely closed if the oven does not start.

Child lock does not allow children to play with the oven, changing settings and independently launching the device. The furnace works normally, lights up and responds to the input, without starting. Hold the button with the lock icon for a few seconds to turn off the child lock.

The easiest way to check performance after replacing parts is to simply try reheating food.

Features of repairing specific models

The reasons for this breakdown are almost always the same, regardless of the microwave oven model. But, nevertheless, some minor differences in their repair are still available:

Checking the operation of capacitors on the electromagnetic lamp

Some ovens do not start if the clock is not set. The installation could be erased if the power was interrupted by the device. Follow the instructions in the instruction manual to set the time and re-enter the cooking instructions.

Some microwaves have a demo mode that shows the functions of the device in the cabin, without activating the magnetron, the part of the oven that generates heat. The controls light up and the oven takes in the input, but the timer often runs at double speed. Turn off the microwave, wait at least a minute and reconnect the power to cancel the demonstration mode. You may have to hold several buttons when the power returns again to completely cancel the demo mode - check your manual.

Do not allow breakdowns microwave

in no case do not heat the food in a metal dish or in containers painted with metal paint. Gold plated or silver blotches can also be dangerous. Such paint will immediately spark, and may catch fire;
do not turn on the microwave without the presence of inside objects for heating. This is detrimental to the device itself;
use a protective cover to avoid rapid contamination of the microwave. Especially if you warm food, which has a tendency to "explode" when warming up (raw eggs, etc.). Such a cover increases the life of the microwave;
do not heat food in tightly closed containers. Hot steam must be able to get out of the tank;
it is worth once a few years to give the oven to the diagnosis of the master. This is especially true of cheap models, as they often fail;
be careful with mechanical parts. If you actively slam the door too hard or do not press the button fully when you open it, you risk breaking the latches.

There is an easy way to check the oven door. Try inserting a sheet of paper through the closed door. If it works out - repair is required.
It is necessary to clarify a certain misconception that arises in relation to microwave food. The only real danger is the use of containers or those that do not have a label that reads "microwave safe". Plastic products are known to tend to melt when heated excessively. This, in turn, detects harmful chemicals that cause danger to human health and further pollute the environment. As research shows, this is the most susceptible threat from the use of microwaves.

Sometimes, it happens that when you put food to heat up, you can find that the oven has stopped heating. Everything works, turns and glows, but the food remains cold. In order not to carry it in for repair, you can try to fix the problem yourself.

Does not warm the microwave: reasons

The main reasons for the breakdown of the microwave oven are hidden in its incorrect operation.

Why the microwave does not heat

Thus, the secret lies in understanding how and what to use when working with a microwave oven. Another myth regarding heating food in a microwave is that all existing food is lost when it is heated in a microwave. The World Health Organization assumes that food in a microwave oven has the same meaning as before it is heated. They also state that no microwave energy remains in food when the microwave is turned off.

Why not warm

This ignores another misconception that food heated in a microwave becomes “radioactive." A banalor-based nutritionist, Dr. Anju Food, a nutritionist, says: The myth that heating food in a microwave is dangerous has not yet been proven. For short heating times, the microwave oven is not dangerous if ceramic and proper containers and heating are used.

Most often, problems with a microwave begin after:

There is a metal object in the cooking chamber;
Warming up food in a dish not intended for this;
Worked an empty oven.

If there is a metal product in the cooking chamber, the microwave immediately starts to sparkle and does not heat the food. Breakage may occur if you use inappropriate for this dish. If the dishes are closed, then when it reaches a certain temperature, it explodes, and the food immediately scatters around the chamber, completely clogging up parts of the oven.

It is very important that certain safety standards are respected in order to ensure optimum use of the microwave oven and to get the most out of it. This will help to think rationally and to confront the existing ones. Microwave ovens are designed in such a way that the waves flow only when the oven is turned on. Thus, it does not create any danger for the environment where it is located. It is extremely important to keep the furnace running, and it must be maintained in proper condition. Only with poor maintenance and excessive damage does the microwave oven pose serious threats.

If an empty microwave is turned on, it sparkles, the magnetron breaks down and the oven no longer heats.

Cheap microwaves can break down simply due to wear. To determine why the microwave broke down, you need to know how it works. The microwaves produce a magnetron, which is connected to the camera and the waveguide. In some individual models, the waveguide is covered with mica, and in others with a plastic cover.

Overheating is the main reason why accidents occur in the kitchen. Therefore, it is important to maintain the stove regularly to prevent leakage. due to leakage can be dangerous. Avoid standing in front of the oven door when heating or cooking. If the necessary precautions are strictly followed, the use of a microwave should not be taken as a threat.

The opinions expressed in this article are the personal opinions of the author. All information is provided on an “as is” basis. America's most convenient device - microwave ovens seem to be an absolute necessity in today's fast-paced world. They are currently present in at least 90% of homes in America because of their ability to cook and reheat food or drinks simple and fast way. Most people have no problem using this kitchen appliance and often find that they are a reasonable alternative to conventional ovens for reheating or cooking.

Nutrition magnetron helps to ensure:

Transformer;
Diode;
Capacitor.

The supply circuit often has a fuse that protects the transformer from overvoltage. A fan is used to cool the magnetron. So that the microwave oven could not function with a door that was not very tightly closed, special interlocking microswitches were installed. That is why until the buttons are pressed and the doors are not closed, power is not supplied. One of the reasons that the microwave does not turn on - sticking or breaking these small parts.

How the use of microwaves negatively affects your health.

However, you may think twice before using your microwave, as there are actually many microwave hazards that you probably don't know about. In short, microwaves are kitchen appliances that are used to prepare or heat food by radiating microwaves. Microwaves are a form of electromagnetic radiation and are located on the low energy end of the energy spectrum, and secondly, by radio waves. Waves are generated by something called a magnetron - something is found in every microwave oven.

There may be more serious reasons for the fact that the furnace has lost its efficiency. This may be due to a faulty fuse, problems with the magnetron, capacitor or mica plate. Ways to fix the damage largely depend on why the failure occurred.

The microwave oven has simply become an indispensable attribute in the kitchen, as it is difficult for many to do without this assistant, who will help to cook and warm up their favorite dish. Microwave breakdown causes a lot of trouble, therefore, it is important to know for what reasons a malfunction may occur in order to perform an independent repair.

Microwaves produced in a microwave oven cause dialect heating - they bounce inside the oven and are absorbed by what is placed in the oven. Check out the research that links microwaves to cancer, diabetes, and nutritional deficiencies.

Determination and Troubleshooting

In order for something to be heated in a microwave, water must be inside the substance. If there is no water, heating will not occur, and it will remain cool. The reason for this is that the water molecules inside the food vibrate at an incredible speed, creating the molecular friction that is responsible for heating the food. The structure of water molecules is broken and energetically deformed. This is very different from any other cooking method, since other methods, such as convection ovens, heat the food by transferring heat convectively from the outside to the inside.

If the oven has stopped heating properly, then the reasons for this may be hiding in:

Insufficient voltage in the network;
A miniature breaker broke;
A high voltage fuse broke;
The transformer does not energize.

In addition, there may be many other reasons why the furnace stops working normally. Initially, you need to call a multimer to determine the voltage level in the network. Then you need to unplug the device from the network and check the miniature switch for operation. The test is carried out using an ohmmeter. If the scale designation is greater than 0, then the part is working normally, if it is 0, then it must be replaced.

If the problem was not detected, then a fuse check is required. For this you need to determine the resistance of the tester. In case of a failure of the condenser, then when the microwave is working, it is very noisy. Important! If there is not enough knowledge and skills to repair microwaves at home, you should take the device to a service center.

Repair microwave ovens with their own hands at home

To be able to independently repair the microwave, you definitely need to know why it broke. Instructions for use of the device will help to repair the stove, as it describes the microwave device in detail. Disassemble the device to start with the top cover. Before this, it is necessary to completely disconnect the furnace from the power supply network and only then proceed to troubleshoot the problem.

After removing the top cover, access to the transformer with two fuses opens, one of which is located on the part itself and belongs to low-melting, while the other is mounted on the furnace body itself and is made of ceramic. In addition, a duplicator unit and a diode are located nearby.

Important! Do not immediately touch the capacitor after removing the top cover, as it holds the voltage for a long time, which can lead to an electric shock. Quite often breakdowns occur in the area of the mica plate.

All pollution begins to burn with time, which leads to the fact that the microwave:

Bad twists;
Humming;
Crackling;
It shoots.

It is quite simple to repair such a breakdown yourself; you just need to purchase a mica plate and cut out a product of the required size from it. If during heating a non-characteristic crackling and sparks appear, then it is necessary to replace the mica plate, which can be damaged by heated oil or any other fat.

Why the microwave does not heat

If the microwave started to warm up the products weakly, then it is necessary to determine the existence of a problem in time and to carry out repairs.

If the oven does not start, the main reasons for the breakdown may be that:

There was a break in the door latch;
Microswitch failed;
Mains fuse blown;
The mica plate burned out.

If the microwave oven smokes, this may indicate that the power transformer has broken. If the touch panel is lit, but the food does not heat up at all, the reason for this may be that a high-voltage diode, magnetron, or capacitor has broken. When the plate stops rotating, the cause of this may be a faulty drive motor.

From a strong voltage surge, the microwave shuts off completely and stops working. In this case, be sure to contact the service center for repairs, since the failure can be very serious and you will not be able to handle it yourself.

Firms and quality: the microwave works, but does not heat

Microwave ovens are produced by many companies.

Among which you need to highlight such as:

Samsung;
Panasonic;
Rainford;
Rolsen;
Scarlet;
Sharpe;

The Samsung M1712NR, Sharp R2371K, Daewoo and many others are considered to be quite popular. After studying the instructions of these types of microwaves, you can determine the presence of a problem, as well as timely repair work. If the furnace began to work poorly, then before starting the repair, you need to perform a comprehensive diagnosis. In this case, according to the instructions you need to completely disassemble the device to inspect every detail.

Broken fuses can be visually identified as they turn black and swell. Even if there is no visible damage, then you need to additionally check the resistance, using a special tester for this.

If the microwave does not break down very much, then it is quite possible to repair it yourself. When the problem is caused by the functioning of the power supply network, it is worthwhile to install an uninterrupted power supply, which will enable the device to always receive the required voltage. In addition, it is advisable to disconnect from the outlet to which the oven is connected all other household appliances, in order to avoid network overload. Incomplete closing of the door is easily eliminated by repairing the latches or replacing them completely.

If the microwave oven starts for a long time or writes an error code on the display, you should take it for repair, as it is often possible to determine the presence of a fault only with the help of special devices.

Do I need a repair: why does not heat the microwave

Often it may be that when you turn on the microwave starts to spark, buzz, immediately turns off. In addition, it happens that the pan rotates, but the smoke went off, the sensor does not shine, and the oven itself cracks, this can be a sign of a very serious breakdown and in this case, often, the microwave requires writing off. It is also necessary to write off the device if the oven exploded, as it is impossible to repair it in this case.

Among the possible causes of failure can be identified such as:

Insufficient mains voltage;
The Start button does not work;
Condenser breakdown;
Doubler does not work;
The body broke down.

Often it is enough just to close the door tightly. The fault can be determined if the device is in standby mode or the timer flashes, but the oven does not work. In this case, it takes only a few seconds to fix the problem.

Microwave faults and solutions

If an error occurs with a microwave oven, it is imperative that all the details be tested beforehand, so it is called by special testers. In some cases, it happens that simply does not go charge to the device. In addition, a transformer often burns out; there may be disturbances inside the furnace, since no discharge is transmitted from the magnetron to the furnace body.

Be sure to repair the microwave, in case it:

Spark;
Turned off;
It stinks.

It is quite possible to carry out repairs on our own, the most important thing is to seek help in a timely manner. If a particular part burns, it is imperative that you first discharge the microwave oven and only after that do the required work.

Do it yourself microwave repair (video)

If problems started with the microwave, it turns on, but it does not heat the products, then you should immediately start repairing, so as not to cause even more damage. What to do with a multimeter and what are the next steps, we have disassembled.
