Electric Oven/Grill Tripping Main Circuit Braker

[KJR]

Looking for some advice. My parents have just bought/moved into a retirement flat with an electric oven/grill which, when you turn the temperature dial, trips the main circuit breaker/RCD and not the cooker circuit breaker/rcd.

The flat is about 10 years old and we assume the oven/grill, AEG/Electrolux, was new when the flat was built but does not appear to have ever been used as it is spotless. The previous owner died so we cannot confirm this.

There is power to the oven/grill as you can set the digital clock and can select either the grill or oven function and the internal light and fan come on. Touch the temperature control and the main rcd trips.

My parents had a domestic appliance engineer out today and he claims that, as the oven/grill does not appear to have been used, then moisture has got into the elements and this is causing the trip.

Any thought or advice appreciated.

That sounds odd. Normally theres at least two elements only one of which is likely to be at fault (if not something else). Did he insulation test the oven/components?

hairyben,

it does sound a bit odd as there are two separate elements. The "electrician" did nothing other than turn the temp dial and it tripped.

Royce44,

my father and I managed to replace the oven element at their old house so we will have a go at disconnecting the elements in this one and see if it still trips.

Did an internet search and, as my father has a multi meter, will try a continuity test on the elements.

Thanks for the advice.
