Microwave Not Heating? Do This Before You Call a Technician

When a microwave turns the turntable but does not actually heat your food, the fault is usually internal rather than something you fixed with a simple reset — but a few quick checks are worth doing first.

Check the door latch. Most microwaves will not run the magnetron if the door sensor thinks the door is not fully closed.

Listen for the hum. If you hear the fan and turntable but no low hum, the magnetron or high-voltage diode has likely failed.

Avoid opening it up yourself. Microwaves store high-voltage charge even when unplugged, which is why microwave repair should always be left to a trained technician.

Findafix microwave technicians in Nairobi diagnose and repair heating faults, door issues, and control panel problems for Samsung, LG, Bosch, and Ramtons microwaves.
