    got to be a main power board fault.
    not looked at these boards so don’t know what type of power supply they use but it may be fixable

    Not a fault associated with the magnetic door switch then?

    If the magnetic door sensor switches on and off randomly it would give the symptoms you describe. Often the cure is not replacing the sensor but that the door hinge bearings wear and the door drops by as little as 1mm. So you might want to check the nylon bearings for wear.
