• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

Microwave functions okay, but fan turns on when door is opened without selecting any microwave functions. Turntable does not rotate when door is opened, but fan turns on. Magnetron was replaced two months ago and all was working fine up till now. Please advise.

It sounds like it could be a door switch issue. Try checking the door switches for continuity with your meter. Check the switches by opening and closing the door and not by pushing the button on the switch.
