• ** 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.

Unit has blown two thermal fuses in two months. Otherwise runs okay. Exhaust fan not running either time, Magnatron cooling fan running properly. Both times blew approx. 2-4 minutes into cooking cycle and range below unit was cooking other food. Unit over temp thermostat has tuned exhaust fan on automatically before but not in either instance of fuse blowing. Magnatron is obviously getting to hot, but what to check or do now?

Is this microwave under a year old?

If its getting to hot usually the bad part is the MAG.

Look at end of the antenna on the mag tube and see if it is burned or pitted. Here's the part you need:
WB27X11079 Magnetron Asm
