Possible Causes
Stuck fan relay on control board, Shorted fan thermostat (if used), Software glitch in control
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing internal components.
- Power reset: Turn off the breaker for 5 minutes, then restore power. If the fan stops and behaves normally afterward, it may have been a control glitch.
- Check fan thermostat: Some models use a cooling fan thermostat. Test it for proper open/closed operation at room temperature. Replace if stuck closed.
- Control board: If the fan runs continuously regardless of temperature and thermostat status, the fan relay on the electronic oven control board may be welded closed. Replace the board.
