Replacing a bathroom fan motor is a lot easier than replacing the whole unit. Since some bath fans are mounted from the attic, removing the whole unit can be cumbersome and difficult. Either way, it is much easier to simply replace the motor itself since 95% of the time, the bath fan motor is why the fan will quit working.
Hints That Your Bath Fan Motor Has Gone Bad
- You hear a squealing sound when the unit is running
- The breaker for the fan trips when only the fan is running on said circuit breaker
- The GFCI, which should be present and connected to your bath fan, shuts off when the fan motor is running
