HJA3200 Unusal fault?

[RocketMan]

I’ve worked on the above appliance:

Reported fault: The oven light goes out, trips part of the CU which cuts the lights basically but the oven remains on! I’ve checked the bulb and the holder, new bulb, still the same. Tried using the oven without the bulb, still the same.

Insulation is ok when cold. I can only presume it’s an element that faults when it gets warm but why does in not trip the oven only part of the CU?

Anyone got any thoughts?

I am assuming what you are saying is the oven trips the wrong rcd

got to be something in common. have you looked at the cu for loose terminals?

Yes, basically it trips the wrong RCD. I’ll check the CU for loose terminals as suggested. Thanks

I don’ t think its your responsibility to look into the consumer unit issue.
(Unless of course your a qualified electrician.)

The cooker is quite often not wired into the RCD side of things so that is why it still runs even though the RCD for the lights has tripped.
There may have always been a bit of dodgy wiring going on in there but has never revealed itself.
I would change the element & see if that sorts the problem but still advise the customer to get the consumer unit checked out…

Check selector switch for arcing melting. Ive had one this week.

I had exactly the same fault, turned out the neutral for the cooker circuit was wired into the wrong neutral block in the cFranz

Thanks to all, Everything seems fine. Switch looks fine.The bottom element looks deformed but that’s not unusual. No insulation problems. I’m going to change the base element.

Franz. I’m going to get the cooker fault isolated then probably get a sparky to check the CU…thanks for you tip.
