That’s an odd one for sure? RCD, earth bonding type problem maybe? 😕

Means you’re gonna need to get your Loop Tester out on this one, or megger everything in there at least?

YEah it is wierd don’t know what could cause it to do this apart from the switch itself.

Dansta had a same fault with an Electrolux oven.
Turned out to be circotherm element 😀

I can’t rememebr exactly which model but i have had problems with the switch selector on these ovens ‘sparking’ when switched on or off. It may be worth checking the selctor switch for any signs of scorching or burning…especially on the underneath.
i think the spark/contact break is enough to upset a sensitive 30Ma RCD
