Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave and allow it to cool before inspection.
Steps to check convection fan:
- 1. Confirm mode: Use a convection-only or preheat mode and listen for the fan. If silent, the fan is not running.
- 2. Inspect interior vents: Look at the rear convection outlet inside the cavity for obstructions or foreign objects.
- 3. Avoid blocking airflow: Do not place large dishes directly against the rear wall during convection cooking.
Repair: If the fan never runs in convection modes, the convection fan motor or its control circuit must be tested and replaced by a technician.
