Possible Causes
Stuck cooling fan thermostat, Shorted triac or relay on control board, Miswired fan circuit after repair
How to Fix / Troubleshooting
Safety first: Disconnect mains power before accessing the top or rear panels.
Step-by-step checks:
- 1. Allow full cool-down: Ensure the oven is completely cold; some models keep the fan running until a thermostat cools.
- 2. Locate cooling thermostat: Find the thermostat controlling the tangential fan. Test for continuity at room temperature; it should be open on many designs.
- 3. Replace thermostat if stuck: If it remains closed when cold, replace the cooling fan thermostat.
- 4. Control board check: If the thermostat is OK, the fan relay or triac on the main control board may be shorted and require board replacement.
