Diagnosis: Why a Microwave Stops Heating

When a microwave stops heating, the problem may come from several possible issues:

• Faulty magnetron – the part that generates heat fails.

• Burned high-voltage diode – prevents proper energy flow.

• Defective capacitor – interrupts the high-voltage circuit.

• Door switch failure – microwave thinks the door isn’t closed.

• Control board malfunction – electronic commands don’t reach the heating system.

After replacing the ditail and testing the system, the microwave started heating food normally again.

Signs Your Microwave Needs Repair

• Runs but does not heat food.

• Sparks or burning smell when operating.

• Light and turntable work, but food stays cold.

• Loud buzzing sound while running.
