Possible Causes
High residual heat from long or high-temp cooking, Stuck cooling thermostat, Faulty control logic keeping fan on, Poor ventilation around oven
How to Fix / Troubleshooting
Safety: The fan is low risk, but disconnect power if it runs continuously for many hours.
- Allow cooling: After self-clean or high-temperature use, it is normal for the fan to run until the oven cools.
- Ventilation: Ensure cabinet cutouts and vents meet Etna installation requirements to allow proper cooling.
- Thermostat test: If the fan never stops, test the cooling thermostat for stuck-closed contacts and replace if necessary.
- Control board: If the thermostat is good, the control board may be keeping the fan relay energized and may need replacement.
