Cooker Hood Motor Capacitor
A capacitor is one of the most common causes of a cooker hood fan failing to start or running sluggishly. If your hood powers on but the fan doesn't spin, or spins slowly at all speeds, a failed capacitor is the most likely culprit before replacing the full motor.
Please note: the capacitor image shown may differ from the one supplied, but the replacement will have the same function and will be suited to the motor unit.
What a Capacitor Does
The capacitor stores electrical energy and releases it to help the motor start and maintain operation when your cooker hood is switched on. AC fan motors used in cooker hoods rely on a capacitor to initiate the spinning action — without it, the motor cannot start or runs intermittently.
Is a Faulty Capacitor the Problem?
Common signs of capacitor failure: the fan won't start when the hood is switched on; the motor hums but the fan doesn't spin; the fan runs slowly at all speed settings; the hood worked intermittently and then stopped entirely. If the hood controls and lighting still function but there is no fan movement, replacing the capacitor is the recommended first step before replacing the full motor unit.
