How to Fix / Troubleshooting
Safety first: Unplug the microwave and allow it to cool.
Vent and fan checks:
- Ensure external vents are not blocked.
- Remove the outer cover (with power disconnected) and locate the internal cooling fan.
- Inspect for debris or insulation obstructing the fan blades.
- Spin the fan by hand; it should move freely without grinding.
- Check the wiring connector to the fan motor for a secure fit.
Repair: If the fan is seized, noisy, or not receiving power when the unit runs (requires live testing by a qualified person), replace the fan motor. Reassemble all covers securely before use.
