Possible Causes
Failed convection fan motor, Seized fan due to grease buildup, Broken fan wiring, Faulty relay on control board
How to Fix / Troubleshooting
Safety first: Disconnect power. Ensure the oven is cool before working inside.
Steps:
- Check fan rotation: Remove the fan cover inside the oven (rear panel) and try to spin the fan blade by hand. It should rotate freely. Clean any heavy grease or debris.
- Access motor: Remove the rear panel of the range to access the convection fan motor. Inspect wiring and connectors.
- Test motor: With a multimeter, check motor winding resistance. If open or shorted, replace the motor.
- Control relay: If the motor tests good but does not receive power when fan mode is selected, the control board relay may be faulty and the board should be replaced.
Warning: Do not run the oven with the fan obstructed; this can overheat the cavity and damage components.
