Checklist to help discover the problem and solution to help get a exhaust fan working again.
- Circuit Breaker
- Make sure it is not tripped off. If so reset the circuit breaker.
- The Switch
- Is the fan switch working, does voltage go in and back out of the switch, if not the switch needs to be replaced.
- Exhaust Fan
- Does the fan motor spin freely. Due to the air passageway the fan motor assembly can get very dirty and require cleaning.
- Lubricating the Exhaust Fan Motor
- A few drops of light machine oil at each end of the motor shaft may be helpful as well.
