Possible Causes

How to Fix / Troubleshooting

Safety: Disconnect mains power before inspection.

Steps:

Observe whether the tangential cooling fan runs continuously even when the oven is cold, or fails to run when hot.
Access the fan and check for free rotation and correct wiring.
If the fan is very noisy or hot to touch, the motor may be failing and should be replaced.
If the fan itself is fine, the main control board relay controlling the fan may be stuck or not energizing correctly, requiring board repair or replacement.
