hi guys this one has an earth fault , feckd if i can find it thoughthe earth and neutral are bridged out , i just cant find where , ive checked the main switch , i can see all the pcb@s are clean ,what i do see is a lot of carbon on the relay contacts any ideas thanks
i would start by disconnecting all the elements and the lampholder and see what happens from there
after that its a question of disconnect and see if it goes.
also if the oven is on a switch and cant be disconnected make sure the neutral is switched because neutral and earth are joined at the substation so will read as an earth fault when there is nothing wrong
