Possible Causes
High residual cavity temperature, Faulty temperature sensor near electronics, Stuck fan relay, Poor ventilation around oven
How to Fix / Troubleshooting
Safety first: This is usually a safety feature, but if the fan never stops, disconnect power before internal checks.
Checks:
- Ensure that ventilation openings are not blocked and that the oven has adequate clearance in the cabinet.
- After long or high-temperature cooking, allow extra time; some models run the fan until electronics cool sufficiently.
- If the fan runs indefinitely, test the relevant temperature sensor and replace if it reads incorrectly.
- If the sensor is good, the fan relay on the control board may be stuck and the board should be replaced.
