Possible Causes
Shorted cooling fan triac on control board, Stuck fan relay contacts, Shorted wiring causing constant fan supply, Control board logic fault
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the control board.
- 1. Confirm behaviour: Restore power and observe if the fan starts immediately without any cooking function selected. Turn power off again.
- 2. Inspect control board: Remove the control panel or top cover to access the main board. Identify the cooling fan relay or triac. Look for signs of overheating or cracking.
- 3. Wiring check: Ensure the cooling fan is not accidentally wired directly to mains due to a previous repair. Correct any miswiring.
- 4. Replace control board: If the relay or triac is welded closed or the board is damaged, replace the main control board. Component-level repair is not typically supported.
Running the cooling fan continuously is not dangerous but indicates a control fault that should be corrected to avoid further board damage.
