Tracing an electrical wire feeding an extractor hob

[dominoman]

Yesterday our whirlpool 769gy electric extractor hood stopped working.

It is fitted inside the chimney breast so I removed the screws and took it out to see if there is a fuse. However when i tested the electric cable coming in to the hob there is no current or voltage at all.

I can't think what could cause it. It works one minute and then not the next.

I've checked the obvious places like the switchboard but everything there is ok. Nothing else stopped working.

Any ideas what it could be?

How can I trace the cable? Everything is covered and I can't even see where the cable goes to.

IF it has been fitted properly, somewhere there will be a fused connection unit (FCU) with a switch.

That may be in an adjacent cupboard, or alongside one of teh wall sockets.

It is very common for the lamp in the extractor hood to fail and to blow the fuse in the FCU.
I've also had a call out to someone who had leant their breadboard on the switch. Easiest £50 i have ever earned..

I would assume you don't expect any repeat busness from that customer then.

Why? A call out is a callout, and £50 is not unreasonable.

Yip, call out is a callout i would agree .

Kind regards,

I suggest using a basic metal detector, like those pipe/cable detectors and seeing if you can find out where the cable runs in the wall using the detector and trace it that way.

It all depends on the situation. The day, the time, whether any further business could be forthcoming, etcetera.

Unfortunately I haven't found anything in the house that has been done properly so far. It is just a series of DIY jobs, mostly done pretty poorly.

As the cable is dropping down in the chimney cavity and there is definitely no entry point in the kitchen I guess it must be entering in the bathroom upstairs (tiled and no access anymore) or in the roof.

In the roof there are lots of cables but I have no idea where any of them lead...

Where would you even start looking?

Sorry not much help. Sounds like youve tried the obvious things.
I'd get an old crusty experienced electrician to look at it. Someone who has seen it all before……...

He does. It was his Mum.
