    Good afternoon,

    Does anyone have a wiring diagram for the above oven that they could forward?

    I replaced the main pcb/module about three weeks ago, as it had blown near a relay.

    However, the elements tested as fine, and I too a gamble on replacing the above module, hoping that it was purely a board failure.

    All was well until yesterday, when the customer reported that it was tripping again.

    So, clearly there is an underlying fault and I would be grateful if I could have a look at the wiring diagram prior to re-visiting tomorrow.


    Kind regards,

    jonty

    When u say blown I assume you mean a track has blown. I would say it’s unlikely to be a board failure if this is the case.
    Did the old board have the same fault?

    If it is a track did you buzz through the wire that the track feeds ?

    If you have not check the lamp holders

    Have no access to circuits for these sorry

    Good afternoon Dave,

    Grill element found to have been the cause of board damage; thankfully it hasn’t do so again.


    Best wishes,

    jon
