Microwaves are a common kitchen appliance in households, and it's inevitable that they may encounter some issues during use. Instead of calling a repairman every time, you can handle some simple problems yourself, saving both time and money. This article will discuss common microwave malfunctions and repair methods, offering assistance to those without experience in home appliance repairs and inspiration to those who are veterans in the field.

1. The turntable does not move after being powered on.

This situation is typically due to a turntable motor failure. Most microwave ovens follow a similar procedure: simply remove the turntable, brackets, and other removable parts inside the microwave, then flip the microwave over so the bottom is facing up. At this point, unscrew the bottom screws of the cover at the turntable motor location, lift off the cover, and you'll see the motor, making it easy to either repair or replace.

2. The appliance fails to heat food upon being plugged in.

If the power plug is not the issue, inspect if the microwave door is properly closed, check if the timer switch is displaying correctly. For smart microwaves, operate as per instructions and verify if the settings are accurate. Also, ensure proper operation. Then, handle the fault accordingly.

The unit can be heated normally, but it cannot be stopped once the timer reaches the set time.

In this case, it indicates that there's a short circuit within the microwave's internal circuitry. You will need to isolate the short circuit and then replace it with a fuse of the same type and specification.

The indicator light is not illuminated, but all other functions are operating normally.

This situation is likely a faulty bulb, which can be resolved by replacing it with a bulb of the same specification.

5. During operation, a sudden freeze occurred.

This could be due to a faulty fuse or a damaged high-voltage protection device. If fuses or other high-voltage protection devices are frequently failing, it's time to inspect the door interlock switch, magnetron, high-voltage diodes, high-voltage transformer, and whether they have been burned out.
