Microwave does not heat, but it works. What to do?

Microwave does not heat ... There is light, the plate turns, the fan hums, but food or water does not heat up. When such a simple, but not very cheap and necessary thing, like a microwave oven, is easier to repair than throw out, all the skills of household appliance repair are put into practice. All that is necessary for a positive result is an elementary knowledge of the basic arrangement of electrical engineering, electronics and, at the very least, the skills of searching for information on the Internet.

More often than not, the topic of repairing microwave ovens does not attract much interest from many owners. Like, there are no spare parts for sale, workshops "break" the prices for restoration and so on. In fact, the work of the microwave oven can be restored, and it will last for a long time, besides, the imported parts are successfully replaced. Cheap and angry.

So, let's begin. The most "sick" question: "The microwave works, but does not heat. What to do?". Everyone knows that in order to understand the problem, first of all you need to disassemble the broken equipment. And, if there are no visible defects, check all the contacts. We disconnect the stove, remove the lid (no difficulties should arise). Next, you will have to do the following: unfasten all the terminals, process the contacts with small nazhdachkoy and assemble in reverse order. Particular attention should be given to power contacts in a transparent braid. Check for signs of burns.

Checked - collected, but the microwave does not heat? It is necessary to measure the voltage in the network. It is worth to clarify that most microwave ovens with a voltage of even 205 V will not heat anything. Check the sockets and extension cords. Everything okay? Then we take it apart again. We need to measure the voltage at the input of the mains transformer. We connect the tester, turn on the microwave oven and start the operating mode, that is, microwave heating. Now the options, why the microwave does not heat, is less.

There is another simple version of the malfunction, in which case the microwave works, but does not heat. This is a fuse. They are usually in the microwave system two, and the output of any of them out of order leads to its inoperability. The solution is trivial. We take the sample (different fuses can be used on different models) and buy the same in the nearest radio store. The cost is about 30 rubles. But many still prefer the installation of "bugs". Be careful. We in no case recommend you such a "replacement".

First, such "refinement" of the design is unsafe. Fire danger is extremely high, and you risk losing not only a microwave, but also a large part of the property. Secondly, even if you picked up the wire of the corresponding section, which more or less meets the safety requirements, is it really 30 rubles - so high price for a new fuse? Buy, set and be absolutely calm. The only issue remains the cause of the failure of this part. And even if you figured out why the microwave does not heat - this is not a fact of troubleshooting. It is possible that the fuse has become, as they say, a symptom. It is not difficult to verify this. If everything works fine, but after a day or two again the microwave does not heat, you'll have to go to the service center or to the store for a new "heater".

In addition to non-essential reasons, of course, it may be that the microwave does not heat because of wear or poor-quality components. If you are confronted with a second reason, and the microwave oven is bought recently, bring it back to the store. Remember that you can "open" the equipment only after the expiration of the warranty period. Otherwise, the warranty is void.

Do not forget that bold experiments can be risky. If you do not feel confident in your knowledge and abilities, leave microwave repairs to professionals.
