Possible Causes
Failed hood/exhaust fan motor, blocked vent duct, defective fan speed control on main control, loose fan wiring
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before working on the exhaust fan system.
- Check vent filters: Remove and clean the grease filters. Replace charcoal filters if they are saturated (recirculating installations).
- Inspect exterior vent: Make sure the wall or roof vent hood is not blocked by debris, nests, or paint.
- Test hood fan: With power restored, try each hood fan speed. If the fan does not run or hums loudly, the hood fan motor may be failing.
- Access fan motor: Remove the upper cabinet mounting screws and lower the unit slightly if needed to access the hood fan motor. Check wiring connections.
- Replace fan motor: If the motor is seized or open, replace it with the correct KitchenAid hood fan motor assembly.
