Doesn't heat up and turn table stop working - LG Over-the-Range Microwave

The table motor belt may have detached which stops table from rotating and the magnetron control shuts off the heating if table does not move. Need model number etc for the microwave. It is not recommended to open the units unless you are qualified technician or understand the operation of the microwave oven. The voltages and waves can harm human body.

It is one of two things, a defective door switch, "most likely" or the keypad control board is faulty.

It is good that the microwave does not work all together. It might be an interlock button or even a relay connection burn on the main mother circuit board.

Need a qualified technician. The service manual will be like $20-50.

Check the three microswitches in the latch assembly.

the turn table stopped and the unit stopped heating.What should I do?

The problem is the magnetron. This is the part of the microwave that heats the food. partselect,com likely has your part with a diagram and great prices.

Check the door safety interlock micro switches for fault or damage.
