Cooker Extractor issue

[jay888]

Hi,
My cooker extractor stopped working along time ago (completely dead, no lights etc).
Excuse the stupid question, but how do I determine if it is the mains supply or the extractor that is faulty?
Thanks in advance.

do you have a mulitmeter and know how to use it ?

 

[jay888]

I can borrow one, I've not used before.

Can you see where the extractor cable connects to the mains supply ,either by a plug and socket ,or a connection unit maybe ?

It's switched off in the photo by the looks of it on the grid switch or is that deliberate?

Hi, thanks for your reply. There's one black wire from the unit that dissappears in the direction of the mains socket. I've just found a plug above left of the fan too. Pics attached.
Thanks.

Hi, yes it's deliberate, but you're right to point it out

Try plugging another item into the socket ,lamp ,hairdryer to prove the socket is ok. If socket is ok ,change the fuse in the extractors plug. If it still doesn't work ,and doesn't blow the plugs fuse ,then there is an issue within the extractor unit.
Your pics seems to have a black wire at one side ,but a grey one in the plug . Is that so ,or just a misleading picture ?

Thanks Terry,
The black wire seems to goes from the motor to small black box.
The grey wire goes from the plug to this unit above the extractor controls.

Obviously the grey wire is supply into the extractor unit ,and the black an lnternal wire to the motor.
First thing to do is as I posted earlier.

All fixed, embarrassingly because of one 3a fuse!

Fuse blows for a reason ,if you haven't found out what caused it to blow ,it may well blow again.

Fuse blows for a reason ,if you haven't found out what caused it to blow ,it may well blow again.

Or it could equally well just be old age, or undersized.

In my experience, 99% of kitchen extractor faults is that one of the lamps has blown, which takes out the 3amp fuse.

So no mystery. Put in new fuse, change the faulty lamp.

Next patient, please.....
