Question about fuse tripping

[CookerHood1]

When I turn my cooker hood on, the fuse trips on our circuit board cutting power to electrical sockets and lights.
Presumably the way to sort out the problem is to get a repair person to look at cooker hood and not to call an electrian to check the electrics?

Any advice would be greatly appreciated!

A repair person will look at the hood, tell you it is an electrical problem and then either fix it or tell you to get a new one, or might advise you to call an electrician if it is a serious problem in the fuse box or something. A repair person should be competent to deal with the cooker hood and wiring it into the electrical system.

An electrician would not necessarily know what is wrong with the cooker hood.

I suppose you could phone a repair person and an electrician and see what they say.

I'd call an electrician.

I'd call an electrician to get him to look at the wiring for the hood. Yes you are right that it's tej hood that is likely to be the problem.

Thanks all for your advice.

I know that the general wiring to the rest of the house is ok. It has recently been checked extensively by an electrician as we had a problem of one of the main fuses on the fuse box tripping intermittently.

When the electricians came out about the intermittently tripping fuse, they turned off all electrical appliances to test our electrics and found no dodgy wiring problems.

They concluded that the tripping was due to a faulty outdoor socket and replaced it. This appeared to stop the intermittent tripping on our circuit board.

However, I now realise that when we turned all the appliances back on, the cooker hood was left off as we rarely use it. When I tried to turn the cooker hood on last night, it kept tripping the electrics. I now have come to the conclusion that the intermittent problem with the fuse tripping we had before was down to the cooker hood all along!

It could be if the power the hood has is too much for the fuse, causing it to trip.
Or the power from the hood going through the wire is too much for the circuits.

I'm no expert - just a theory (based on fuses tripping in our old house).

Possibly, although the cooker hood has not caused any problems previously and had been there 12 years.

Hard to know, but we called an electrician when our cooker kept tripping our trip switch. Turned out something hadn't been installed correctly in trip switch box when house was rewired about six years before. He sorted and haven't had a problem in the following four years.

Just reading others replies, which reminds me in our last house we had works done and electrician picked up we had a massive spur off the main electrical circuit, which meant if a lot of things were in use on it, it wouldn't cope. The spur was added onto circuit system from DD's bedroom into a new extension and then out to shed, so if there's been lots of electrical work in past that could be an issue if you've got too many things in use in one go.

It is difficult to know for certain because it is rare for only one appliance to be wired into a particular circuit on a breaker. For example it could be the cumulative load/leakage current on that circuit that causes it to trip when extra appliances are switched in rather than a fault with the switched in appliance itself. In other words, wot she said ^

Still I would recommend getting in an expert to look at it as soon as possible and would not use the switched in appliance until you have had it checked over, as it is the most likely thing to be at fault.

Assuming it's a modern circuit breaker, they are very sensitive but they are also there for a reason. The fact that they are tripping means they are doing their job so you're unlikely to set the house on fire. However, electricity needs to be treated with respect so I wouldn't just ignore it.
First thing I would do is try and verify if it is solely the hood at fault and not a combination of factors. So turn of everything else on that circuit and see if turning on the hood still causes the breaker to trip. Then, turn off all the individual components of the hood (usually lights and fan) and see if you can isolate the cause down to the hood itself, the lights or the fan. e.g. turn on hood with lights and fan off. If that doesn't cause a trip, turn on the lights. If that doesn't trip, turn on the fan. Rinse and repeat as necessary.
If you're really, really lucky it might just be that the bulbs you have fitted are the wrong specification and can be replaced. Otherwise, it will probably work out cheaper just to buy a new hood. You could get an electrician in to look at it but that will probably cost you as much as a new hood which may well end up being their recommendation anyway.

Thanks everyone for taking the time to post.
I have decided to call out an appliance repair person, who hopefully should resolve the issue. Thanks @WalkingThroughTreacle for your post on how to narrow down the fault with the cooker hood. I intend to follow your advice and will report back.
