First, it may be that the circuit pressure is too high, resulting in poor contact or uneven heating. If this is the case, just adjust the voltmeter or avoid the peak power consumption.

Second, the battery may be low. If this is the case, just replace the new battery or charge it.

The third reason is that the heating pipe is aging or damaged due to too long use time. If so, you can directly find maintenance personnel to replace the aging heating pipe or repair the damaged heating pipe.

Reason 4: If the display is normal after startup, but there is no microwave output, check whether the secondary coil of the high voltage transformer is open. If it is an open circuit, directly replace the high voltage transformer to eliminate the fault.

Reason 5: The high-voltage safety tube of microwave oven is broken. If this is the case, it can be replaced.

There are many reasons why microwave ovens are not hot. We must find out the problem. Only the right medicine can cure the disease. Otherwise, everything we do is useless. Bian Xiao reminded everyone to check the microwave oven after using it for a period of time. Don't wait until the microwave oven doesn't work properly to remember to repair and check it.
