Possible Causes
Failed main relay on control board, Burned relay contacts, Open wiring to fan/light/turntable, Shorted load causing relay failure
How to Fix / Troubleshooting
Safety: Unplug the microwave before any disassembly.
User-level checks:
- Confirm symptoms: If none of the internal components (light, fan, turntable) operate when starting a cycle, the main relay or power distribution is suspect.
Technician-level checks:
- Inspect the main control board for burned or cracked relay solder joints.
- Test continuity from the relay output to the loads (fan, light, turntable motor).
- Check each load (fan motor, light socket, turntable motor) for shorts that may have damaged the relay.
- Replace the main control board if the relay is defective or the PCB is damaged.
