How to Fix / Troubleshooting

Safety first: Turn off power at the breaker and allow the oven to cool.

Identify noise source: Note whether the noise occurs during convection bake (convection fan) or during cool-down (cooling fan).
Inspect convection fan: Remove the rear interior cover and check for loose screws, bent blades, or debris. Tighten screws and remove any foreign objects.
Inspect cooling fan: From the rear, check the cooling fan for wobble or contact with shrouds. Adjust or tighten as needed.
Replace noisy motor: If the fan still rattles or grinds after cleaning and tightening, replace the affected fan motor assembly.

Note: Ignoring fan noise can lead to complete motor failure and overheating.

Oven makes a loud rattling or grinding noise when the fan is running.
