I have an old Britannia range cooker (model SI-106T-slx-s, art PD1006MP, serial 05380492) with a burnt main selector switch. When I turn on the main oven the RCD trips. The small oven works ok apart from the light inside the oven which blows when replaced. Since the burning has occurred on position 1, the light only setting, I have disconnected the connections (3 blue wires) to terminal 1 and the switch no longer trips the RCD but nor does it turn on the oven. At the back of the cooker, the insulation is burnt around the light fitting to the small oven. Can you help please? Do I need a new main oven selector switch and should I disconnect and isolate any more of the wiring circuit? I have continuity tested the elements and they all seem fine. Also the lighters on the gas hob aren’t working but I don’t know if this is a part of the main problem. I can’t upload the photos as they are too big.
if the switch is burn it will have to be replaced
but
tripping is an earth fault so it could be lots of things
the burning round the lamp is not burning it will be fat deposits coming out of the oven as fibreglass cant burnyour tripping could well be the element

Thank you for that. Is there any significance/clue in the fact that it was terminal 1? I need to know where to begin looking for a leak to earth.
Thank you.
I re-established the power input to the oven selector switch and tried switching the oven on one setting at a time. All of the elements heated up when required by the selector switch. All of the warning lights came on as they should and so did the oven interior lamp. None of the settings tripped the RCD until the oven had heated up to the temperature setting on the dial. Could this still be caused by an element even though they all work? The thermostat tests ok. i.e. continuous until it clicks then open circuit.
