Possible Causes
Stuck cooling fan relay, Faulty temperature sensor near control panel, Control board logic error, Shorted fan wiring causing constant power
How to Fix / Troubleshooting
Safety first: Disconnect mains power before accessing the control board or fan wiring.
Steps to check:
- Allow full cool-down: Some OBH Nordica ovens are designed to run the cooling fan until the cavity and control area are cool. Verify that the fan eventually stops after 30–60 minutes.
- Inspect fan wiring: Ensure the cooling fan is only connected through the control board and not directly to mains due to a wiring fault.
- Control board relay: Inspect the cooling fan relay on the main PCB for welded contacts. If stuck closed, replace the control board.
- Check temperature sensor (if equipped): Some models use a sensor near the control panel to decide when to stop the fan. Test and replace if faulty.
- Test: After repairs, run the oven and confirm that the fan stops within a reasonable time after shutdown.
