Component families associated with this symptom
These are component types commonly connected with this malfunction. They are not model-specific part-number recommendations.
Magnetron
The magnetron generates microwave energy for heating food.
High-voltage diode
The diode is part of the high-voltage circuit supplying the magnetron.
High-voltage capacitor
The capacitor is part of the microwave high-voltage power circuit.
Door switch / interlock switch
Microwaves use multiple safety switches to enable the high-voltage system.
High-voltage transformer / inverter
Transformer or inverter models require a working high-voltage supply.
Thermal fuse / thermoprotector
Thermal protection devices can interrupt the heating circuit.
