    Got a short to earth but for the life in me can not find.. Suspected power module as it does have a link to earth.. changed it but still have same fault? Can not find a fault with a component ie elements/fans/ntc/light etc. There are two boards on this oven 00651994 (changed) and 00656659 control module.
    There is also a switch for the door but it is insulated and I am picking up 002mg ohm to earth via meggar
    Anyone had the same thing I would appreciate help before I dive in further 🙁

    well I would
    disconnect and isolate all elements then try again and see if it trips

    check lampholder as they have an earth connection

    the last problem earth I had was a fan motor

    also one of the problems with electronic board is they have suppression capacitors that are not rated for 500v

    its unlikely to be the boards
