Dead extractor hood, how to check for power?

Paulboy · 29 Aug 2015

We have a fairly new extractor hood which has just died, before I get someone out as it's under warranty I need to check there is power getting to the hood. The connection is behind the chimnry hood which would be a real pain in the arse to try and remove as it's very tight.

I doubt the issue is the connection behind , it's a big connector block (not the normal white ones) and this goes into fused switch, which I have checked and fuse is not the issue.

So how would I check that there is a supply reaching the pcn? Most things I have read about multi meters seem to indicate the power is switched off and used to test circuits etc, but I want to test the supply is not the issue....?

Any help appreciated

Take the filters out. You can normally get to the terminals then.
What have you got to measure with?

Frank, I was just going to pick up a multi meter up from b n q or should I use some thing else?

I assume a multi meter would be the right thing to use ?

Yes a multimeter will do the job

The usual problem with extractor hoods is that one of the light bulbs dies and this often blows the fuse in the feed to the hood.
Usually there will be an FCU that controls the feed to the hood, if you know where that is, check the fuse - there should be one and it should be accessible.

Thanks, fcu checked fuse is fine, they are led lights not halogens

Ahh well, worth a try, back to plan A.
Get multimeter and check for voltage at terminals..

Better plan...don't mess with the hood as it is under warranty from the installer. Check you have power at the spur and check it has an output..you already said the fuse is good...if there is electricity going to the hood then the fault lays within..call the installer/supplier...if you start messing with items under warranty you may be negating said warranty.
