fuse blows after closing door
GE PVM9005SJ3SS fuse blows after plugging in. So, I left the door open before replacing the fuse, and then plug in and then would turn on asking to set clock, and the fuse blow after closing the door.
I checked the three door switches with a multimeter while on and off the latch board and they appear ok. I've inspected the latch board and it appears ok.
I've also multimeter checked the transformer, capacitor, capacitor diode and magnetron and all appear ok. I've also disconnected one of transformer terminal and getting the same result so I'm thinking this is not caused by the HV circuit.
Appreciate your help on my 4-year old microwave.
