Possible Causes
Failed convection fan motor, Faulty convection selector switch (if equipped), Bad fan relay on control board, Broken fan blade
How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before accessing the fan.
- Step 1 – Confirm mode: Ensure you have selected a convection mode per the user manual. Some modes do not use the fan.
- Step 2 – Listen for fan: In a convection mode, you should hear the fan. If not, remove the interior fan cover and check if the blade is obstructed or loose.
- Step 3 – Test motor: With power OFF, access the rear of the oven and test the convection motor for continuity. Replace if open or seized.
- Step 4 – Control and switches: If the motor is good, check any convection selector switch or the control board’s fan relay. Replace the faulty component.
Tip: After repair, test with a convection bake cycle and verify even browning across multiple racks.
