• ** 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.

Operation is intermittent; sometimes works normally. Other times, e.g., when trying to boil a cup of water, the sound will tell that it is on but then goes silent and no hot water in cup.

Is the magnetron (not available is AppliancePartsPros response), door latch, other the likely cause for intermittent operation of this 17 year old machine?

So you're saying you can hear the mag tube humm when it's working normally and when it's not you don't hear the humm. That's a common problem with all microwaves but can be caused by just about anything. It's usually caused when power is lost to the high voltage transformer. That can be a door switch or a control board relay. Intermittent problems are the hardest to diagnose because you usually need to catch it in the act. Next time it doesn't work see if the transformer is getting 120 VAC.
