    Hi guys,

    The 10amp fuse on “f2” (special fuse) terminal on the small mains pcb keeps blowing.

    Any ideas please??

    I carried out insulation tests on whole appliance, the fan element, the grill, the magnetron… it has a main pcb which holds the diodes and transformer/heat sink.


    Sorry!! the enr is H5972NOGB/01

    Replace the fuse, if it blows when you shut the door its the door switch. If it blows once the m/w has started its probably the capacitor and the zener diode which bridges the two terminals. could be the diode that goes from the cap down to earth. Easy enough to check

    This model was fairly good so smart money on the cap and diodes..
