Hi all just wondering if anyone has come across a hotpoint double oven mod no Dh53b with the grill not working traced the fault back to the simmer stat energy regulator changed this part and after 20 mins it trips the electric checked grill element after it tripped and it was to earth so changed the grill element still the same trips the electic and 20 mins but the fan runs constantly so went back today with a base element and a cut in and cut out put the base element on and then I had a dead short traced it to the cut in now I have no light on the grill and ideas?
