Exhaust Fan Will not turn on
-
- Check if fan is getting power – turn off power first, then inspect wiring connections.
- Remove cover and check if fan blades spin freely. Look for obstructions like dirt or insect nests.
- Clean fan blades, motor housing, and vents with small brush or vacuum to remove dust buildup.
- Test capacitors and motors for signs of failure like humming. Replace defective part.
- Check ducting for leaks, gaps, or clogs. Repair and realign as needed to optimize airflow.
- Remove fan motor and lubricate shaft bearings if noisy. Use electrical contact cleaner on switch terminals.
- Make sure ducting is vented to exterior. Recirculation kits can allow moisture buildup.
- Replace cracked or damaged fan housing. Unstable housing can misalign moving parts.
- Install new mounting hardware matched to fan weight if current hardware is insufficient.
- Call an electrician if issue persists after cleaning and component replacement. May require new wiring.
