What is actually happening
A hood where the light works but the fan does not has power, so the fault is in the fan side — the switch, the capacitor or the motor. A hood where neither works has lost its supply, and on many kitchens that is a spur or isolator switch above the units rather than the hood itself.
The usual causes
- A failed fan motor or a seized bearing, often from years of grease
- A failed motor capacitor, where the motor hums but will not start
- A failed push-button or slider switch
- A tripped isolator or spur switch feeding the hood
- Grease-clogged filters overloading the motor
What you can safely check yourself
Work through these in order. Anything past this point — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the appliance plugged in.
- Check whether the light still works — that tells you at once whether the hood has power
- Look for an isolator or spur switch above or beside the units
- Take the metal filters out and degrease them; badly clogged filters can stall a tired motor
Still not working?

Common questions
Why is my cooker hood not working?
The cooker hood fan does not run when you press the button, though the light may still work. A hood where the light works but the fan does not has power, so the fault is in the fan side — the switch, the capacitor or the motor. A hood where neither works has lost its supply, and on many kitchens that is a spur or isolator switch above the units rather than the hood itself.
Can I fix a cooker hood not working myself?
Check whether the light still works — that tells you at once whether the hood has power. Look for an isolator or spur switch above or beside the units. Take the metal filters out and degrease them; badly clogged filters can stall a tired motor. Beyond those checks this one normally needs an engineer.
