Why Does My Exhaust Fan Not Work?
A non-working exhaust fan can lead to moisture buildup, mold growth, and poor air quality. Most issues are electrical, but some are mechanical.
Important Safety Warning
Working in ceiling spaces involves electrical hazards and fall risks. If you're not confident, call an electrician.
Common Signs & Symptoms
- Fan doesn't turn on when switch is pressed
- Fan runs but very slowly or weakly
- Loud grinding or rattling noise
- Fan runs continuously and won't turn off
Potential Causes
Why is this happening? Here are the most common reasons we see in WA homes:
- Blown fuse or tripped circuit breaker
- Faulty switch or timer
- Motor burnout from dust buildup
- Loose wiring connections
Troubleshooting Steps (DIY Safe)
- 1Check if the circuit breaker has tripped and reset it.
- 2Test the switch - if other lights on the same switch work, the fan may be faulty.
- 3Clean the fan grille - dust buildup can cause overheating.
- 4If the fan is old (10+ years), it may need replacement.
DIY vs Professional
In Western Australia, it is illegal to perform your own electrical work. While you can change a lightbulb or reset a switch, anything involving wiring or removing fittings must be done by a licensed electrician.
