Cooker tripping fuse box when NOT in use

Jonesbo

So our power went out sometime between 12am and 5am when nothing was being used.

The fuse that's causing the trip is labelled 'cooker', and everything apart from the cooker is now back on, but flipping that switch knocks everything out.

Cooker itself is a baumatic range with gas hob, and from what I can see is wiŕed into the wall with a switch above the cooker with orange light.

Is this likely to be anything simple before I get an electrician in?

Thanks!

Please dont take this the wrong way, and I dont want to appear patronising but... if you have to ask what can cause the a switch to flip in the consumer unit then please don't fiddle with the electrics yourself.

Just to clarify though is it a fuse (in which case it is a fuse box) or is it a MCB (ie a switch - in which case its a CU).

Don't worry no intention of going anywhere near the electrics myself, just trying to work out the best course of action.

As for your question, it's an RCD box, and the MCB(?) switch labelled 'cooker' trips the main switch when flipped to on. So it's currently off and everything else is working. Thanks

Did something boil over last night? If water got in the cooker's electrics, that will make the trip blow.

Try leaving it to dry out for a day or two then turn the circuit back on.

To add to that, I've just realised there's actually two switches one either side of the cooker. I haven't tried to isolate them yet but will do now.

Hob hasn't been used since Sunday, oven itself was last used yesterday afternoon just to heat something up, so no water has been near the cooker for a fair amount of time before it triggered the RCD box.

If the 'cooker' switch is connected to both the hob and the oven, could well be a faulty part in the latter?
Had the same issue and it turned out the motor for the oven cooling fan (not the main one inside,. but the one that cools the outside of the cavity) had burned out and caused a short to ground (hence the trip).
Fairly simple to isolate and replace, but was more a case of trial and error unplugging different bits till is didn't trip any more.

Well I've just isolated it down a bit further: one switch by the oven controls the extractor hood and this works fine, so it's just the single switch to the oven/hob that's causing the trip.

So could anyone have a guess whether I need an electrician or an oven-repair here??

You need a white goods engineer. My guess is that you may have an earth leakage on the oven that is causing the RCD to trip out. Which is exactly what it's supposed to do.
