What to do if the microwave oven doesn't heat up 1-2

Reason 1: Low voltage

When the voltage is lower than 187V, it will cause the microwave oven doesn't heat up, because the microwave oven must be higher than 187V to work properly.

Solution: Avoid peak electricity consumption when using the microwave oven, or replace the voltmeter.

Reason 2: Insufficient Battery Capacity

The microwave oven's battery capacity is insufficient, which makes the microwave oven does not heat up.

Solution: Charge the battery, or replace it with a new one.

Microwave oven does not heat up how to 3-4

Reason 3: high voltage transformer damage

Microwave oven turned on the light is on but the carousel did not move, can not be heated up, most likely the high voltage transformer is bad.

Solution: replace the high-voltage transformer

Reason 4: high-voltage diode damage

The microwave oven is turned on, the light is on, the carousel is also moving, but it is unable to heat up, most likely the high-voltage diode is bad. You can see whether the high-voltage diode is normal, if the result of the measurement is infinity, it means that the high-voltage diode is bad.

Solution: replace the high-voltage diode

Microwave oven does not heat up how to 5-6

Reason 5: the second door interlock switch is damaged

Due to the operation of frequent, poor contact, electrocution destruction caused by the 220-volt operating voltage can not work properly, which leads to the door interlock damage.

Solution: first check whether the fuse is blown, if not blown, and then see whether the monitoring switch is normal, if the monitoring switch is normal, it means that the interlock switch is bad, replace the new door interlock switch can be.

Reason 6: damage to the magnetron

Microwave oven lights on but does not heat, it is likely to be caused by the aging of the magnetron filament broken.

Solution: test the filament winding, normal is 0 ohms, if not, it means that the magnetron is bad, need to replace the new magnetron.

If the microwave oven does not heat up, you may want to troubleshoot from the above 6 aspects and take corresponding measures to solve the problem.
