How to Fix / Troubleshooting
Safety first: Unplug the microwave. Internal components can be dangerous; avoid the high-voltage section.
- Check vents: Ensure the front, side, and top vents are not blocked by cabinets, foil, or debris. Clear any obstructions.
- Listen for fan: When the unit previously ran, you should have heard a fan. If the fan has been noisy or not running, suspect the cooling fan motor.
- Access fan: Remove the outer cabinet. Locate the cavity cooling fan motor (usually near the top rear). Spin the fan blade by hand; it should move freely.
- Inspect wiring: Check the fan motor wiring harness and connector for loose or burnt terminals.
- Replace fan motor: If the fan is seized or open-circuit (if you can test with a meter), replace the cooling fan motor assembly.
- Control board: If the fan motor is good but never receives power, the main control board may have a failed fan relay and need replacement.
