DIY Microwave Repair

Let's consider the structure of a microwave oven (Fig. 1). (1-electronic control module. 2-microswitches. 3-magnetron. 4-thermal relay. 5-high-voltage transformer. 6-fuse. 7-fan. 8-line filter. 9-storage capacitor. 10-high-voltage diode).

The mechanism of heating (cooking) food in a microwave oven occurs due to the electromagnetic excitation of water molecules contained in the food.

Electromagnetic waves penetrate to great depths and are absorbed by water molecules.

The process of their excitation occurs. The vibrations of water molecules increase. The molecules collide with each other, which leads to an increase in temperature (heating).

What do you need to know to repair a microwave oven yourself ?

The main thing is how a microwave oven is constructed, how a microwave oven works.

Do-it-yourself microwave repair. The majority of belgium telegram data microwaves (almost all), regardless of brand and model, have the same operating principle, therefore, the device and functional units are similar and even interchangeable.

DIY Microwave Repair
1. Electronic control module:

Electromechanical control units are basically mechanics. We turn the timer handle, the contacts close, the engine turns on.

The engine rotates the timer backwards, and the contacts open, we hear a "bell", and the timer stops. The power consists of switching the magnetron on and off.

Therefore, the power regulator sets the on/off periods of the magnetron.

Almost all models of microwave ovens of the latest modifications are equipped with an electronic control module.

The main functions of electronic modules are:
1. Set the heating power.

2. Set the warm-up time.

3. Turn on the grill (in ovens with a grill).

4. Turn on the microwave.

5. Turn on microwaves + grill (in ovens with grill).

6. Clock.

Six basic functions (sub-functions or expansion functions are not so important because they do not have a significant impact on the operation of the microwave oven).

The microwave oven functions are set using the keyboard (Fig. 1.12). I would like to draw attention to the function "1. Set the heating power."
