How to Fix / Troubleshooting
Safety: Disconnect power and allow the oven to cool.
Steps:
- Access the cooling fan assembly (typically above the oven cavity behind the control panel or top cover).
- Inspect the fan blades and housing for grease buildup or obstructions.
- Check wiring connectors for heat damage or looseness.
- Test the fan motor for continuity; an open motor indicates failure.
Corrective actions:
- Clean any heavy dust or grease from the cooling fan and surrounding vents.
- Replace the cooling fan motor if it is seized, noisy, or electrically open.
- If the motor is good but never receives power when the oven is hot, the control board may be defective and should be replaced.
