How to Fix / Troubleshooting
Safety: Turn off power and allow the oven to cool before servicing the fan.
- Listen for fan: When the oven is turned on, you should hear the cooling fan run. If silent, suspect the fan or power to it.
- Access fan: Remove the rear panel or top cover to reach the cooling fan assembly.
- Inspect blades: Check for insulation, wiring, or debris blocking the fan. Clear obstructions.
