Re: Loud pop, bright flash, tripped circuit, dead ovens

Afternoon kwatt,
I’ve not had the power on while I’ve been round the back.
It’s been off on the wall unless I’ve been infront of the cooker, with the top correctly in place only with the various elements isolated at the back, and taped so the metal spade connectors coudln’t touch anything while they weren’t in their female connector on the elements. I know you only get once chance with electrics, so I’ve not been gambling in any way while the power has been on, but have been trying to replicate the problem, which I now can’t, though the bottom over remains dead in all respects (light, fan, heat.) In the mean time between getting it properly sorted, I have some spare loft roll that I’ll insulate the back with so we can use the top oven without losing all the heat out the back.
Thanks for the concern and for the help. Nathan.

A bit more investigation and re-checking resistances.

Cable to the cooker is 6mm2 and is about 15m from the consumer unit.
I re-checked the resistance of the elements on an easier to read scale:
Grill 1: 30ohm
Grill 2: 120ohm
Top oven: 50ohm
Bottom oven: 25ohm

I’ve since removed all the connectors for the elements and taped them up with insulating tape to see where a fault might be by isolating one element at a time.
The bottom oven, whether it’s on its own or not, will not work: no light, no fan, no heat.
The top oven (not fan assissted) works fine on it’s own.
The grill elements both work fine.
The hobs all work fine.

When connecting the grill and top oven together now (they share a blue wire) I get no problem where as before there was the bright flash/pop and the circuit tripped. But I still can’t use the top oven because in my ferreting around at the back in order to check the top oven element I had to remove part of the insulation material which just disintegrated between my fingers. Can you suggest where I can buy this stuff afresh as my internet searches have turned up nothing.

Looking for a local repair shop now to see if they have ideas and possibly a call-out service to try and get this sorted if I can’t do it myself. I’ll be properly annoyed if I can’t get to the bottom of it though. But there is a lot of wiring going on round the back and under the cook top. I wish electrolux did a wiring diagram. If I can fix motorbike electrics I don’t see why I shouldn’t be able to fathom this and get the appropriate parts ordered. Chalk and cheese?
