Cooker hood not turning on: what our engineers find

Cooker Hoods

These figures come from NAC's own repair records: 58 cooker hood jobs our engineers attended for this fault in the last 12 months. Here is what they found, what fixed it and what it typically cost.

When a cooker hood will not turn on at all, with no lights and no fan, engineers sometimes find a simple cause outside the hood itself. A blown fuse in the plug is one, and it often seems to happen when a bulb blows or while a bulb is being changed. Another is that the hood has simply been switched off at its wall switch, which can be tucked away inside a nearby cupboard and knocked off by accident when things are put back. It is worth looking for that switch before booking a visit.

Now and then the fault lies inside the hood. Engineers sometimes find the main control board has failed, and when it goes it can take the touch controls or buttons with it. Occasionally the board shows signs of having burnt, and in that case the hood should be left unplugged and not used until it has been repaired.

An engineer will usually start with safety tests and then trace where the power stops, from the supply through to the controls. A fuse or a switched off supply can be put right there and then. A failed board or control panel often has to be ordered and fitted at a second visit.

No single cause has enough confirmed repairs behind it yet to show for this fault.

About the price. £98 to £110 is the typical total paid by customers, including parts and VAT: the middle half of what customers paid on 34 of these repairs. Repairs paid for by manufacturers and insurers aren't counted, because that work is charged at contract rates. It's a guide, not a quote. Your engineer confirms a fixed price before any work starts.

Before you check anything yourself

  • Switch the cooker hood off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
  • If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.

A confirmed repair is a job we repaired where 60 days then passed with no engineer called back to it. Faults and causes are classified by an AI model reading our engineers' job notes, with personal details removed first, and checked against a hand-labelled sample of NAC jobs.
