How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the fan.
- Identify fan type: Determine if the noise is from the convection fan (inside oven) or cooling fan (behind control panel).
- Convection fan: Remove the oven racks and rear interior panel to access the convection fan. Check for loose screws, bent blades, or debris. Tighten the fan nut and straighten or replace the blade if damaged.
- Cooling fan: Remove the rear panel and inspect the cooling fan near the control area. Clear any obstructions and check that the fan spins freely. Replace the fan motor if noisy or stiff.
- Test operation: Restore power and test. Persistent noise after cleaning usually indicates the motor should be replaced.
