The microwave oven has long been included and firmly established in the list of traditionally used household appliances. Fast food preparation devices raise the level of comfort, save time. But microwave ovens, despite their high degree of technology, are not insured against breakdowns. Therefore, such moments when the microwave oven does not work: does not heat, does not turn on, is not controlled, etc. - these are frequent breakdowns that should be considered. Moreover, many of the breakdowns of microwave ovens are quite accessible to repair with your own hands.

Microwave ovens: malfunctions
Before considering the malfunctions of household appliances of this type, it would be correct (even if superficially) to touch upon the principle of operation of the device.

Heating of products inside the microwave oven is carried mexico telegram data out by electromagnetic radiation. Moreover, only substances that structurally contain moisture are heated.

The inner contents are the electrical components of the microwave. These parts generate the microwave radiation needed to heat the food.
A standard household microwave oven operates at a frequency of 2450 MHz (microwave range).

High-frequency radiation inside the working chamber of the device is created by a magnetron, one of the main components of the electrical circuit.

To generate microwaves, a magnetron requires high voltage – several thousand volts. This voltage is obtained by other components of the circuit:

high voltage transformer;
powerful rectifier diode;
high voltage capacitor;
control and switching circuits.
Microwave oven not working: how to fix
Any of the above points (or several at once) can cause the microwave oven to not work.

Structural diagram: 1 - microwaves; 2 - waveguide; 3 - magnetron cooling fan; 4 - magnetron emitter; 5 - magnetron; 6 - capacitor; 7 - high-voltage diode; 8 - high-voltage transformer
However, in addition to the electronics specified in the list, the microwave diagram contains a number of other components (electrical, mechanical). Some of them are available for repair or replacement with your own hands. Let's see: which, where, when and how.
