Why has my range hood fan stopped?
A hood fan that has gone silent is usually the motor, the speed control or the switch. Grease is the common thread: it works into the motor bearings over years and eventually stops them.
Likely causes
- Fan motor seized, usually grease-related
- Speed control switch failed
- Capacitor failed on larger motors
- Control board fault on touch-controlled hoods
- Wiring connection corroded in a humid kitchen
What we do
We test the switch and capacitor before condemning a motor, because both are far cheaper and fail more often. If it is the motor, we quote the part before removing anything — hood motors vary enormously in price between models.
What affects the cost
Switches and capacitors are inexpensive. Motors range widely, and on premium built-in hoods the motor is a significant part.
