Hey,
My mother has a oven with a grill that she has never used in the 4 years she has owned the oven (Oven been working perfectly for past 4 yrs). A week ago she wanted to use the grill which resulted in the ground floor of the house filling with BBQ smelling smoke (Burning fat on the grill I assumed) followed by the RCD tripping so she gave up on the grill. Few days later she wanted to use the normal fan assisted oven part of it which went fine for a few minutes before tripping the RCD again. Someone came out to look at the oven and she told me the person used some "prongs" on it which I assumed to be a multimeter and could not find anything wrong with it but suggested she try the pyrolytic cleaning function on the oven as she had never gave it a proper clean with it. On the pyrolytic cleaning function is ran for about 2 mins before tripping the RCD again. On a second attempt it successfuly ran the 1 and a half hour pyrolytic cleaning cycle.
However, yesterday she attempted to cook something in the oven but as soon as she turned the oven on (i.e turned it to the fan assisted oven setting - not even adjusting the temp. of oven) - she said she saw a blue flash inside the oven and it tripped the 32A (230V) circuit breaker for the sockets and I told her to unplug it and not to use it until it can be checked out again as electrical arcing can hardly be good now, can it?
I'm not an electrician so I've assumed the following:
The MK 5932s is a 32amp 230v circuit breaker (Which has only tripped the once - with the blue flash)
The MK 5780 is a RCD (Rated for 80A with a 30mA sensitivity)
While concerned, I was not too worried about the RCD tripping as I know ovens leak quite a bit but I'm quite concerned about the circuit breaker tripping.
Is the oven safe to use and why did the person who came out to check it last time not find any fault with it?
Thanks
