Glen,
Check and make sure both breakers are set and locked in place, and you have 220 / 240 VAC to the unit. especially if both the microwave and oven are "dead" or not working.

If the problem is isolated to the microwave, it could be the inline fuse or a thermal limit switch. located behind the M/W control panel. You'll need to remove the top air grille, remove the screw attaching the control panel to the frame and lower it. You can then access the inline fuse and magnetron thermal fuse, make sure you turn the power off to the oven, and don't touch the capacitor, until you discharge the voltage build up.


Thanks and Good Luck,
