Possible Causes
Stuck fan relay on control board, Shorted temperature sensor reading high, Faulty fan thermostat (if separate), Wiring short in fan circuit
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before servicing.
- Allow full cool-down: Ensure the oven has been off for several hours. Some models keep the fan running until the cavity is cool.
- Test sensor: Check the oven temperature sensor resistance at room temperature. If it reads as if the oven is hot (low resistance), replace it.
- Inspect fan thermostat: If your RCA model uses a separate fan thermostat, test it for proper open/closed operation at room temperature.
- Control board relay: If sensors and thermostats are good, the fan relay on the electronic oven control board may be stuck closed and the board will need replacement.
