Oven fan (cooling or convection) is very noisy, rattling, or grinding during operation.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing internal fans. Blades can be sharp.
Step-by-step checks:
- Identify which fan: Determine if the noise comes from the rear convection fan (inside cavity) or the top/rear cooling fan.
- Access fan: Remove the interior rear panel for the convection fan or the top/rear cover for the cooling fan.
- Inspect blades: Remove any debris and ensure blades are not bent. Tighten the fan mounting nut or screws.
- Spin test: Spin the fan by hand. Roughness, wobble, or grinding indicates worn bearings.
When to replace parts: Replace the convection fan motor or cooling fan motor if bearings are noisy or seized. Replace damaged fan blades if separate from the motor.
