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.
