Tip & How-To about Microwave Ovens
Your unit is dead, mains are good, tried power plug in other receptacles, still no power. You more than likely have a bad fuse inside the unit.
Unplug the unit. Remove the cover. Generally this requires removing all the screws on the back perimeter and lifting the cover up or perhaps sliding it off the front. Sometimes the cover will stick due to old grease, etc.
Somewhere in the area of where the power cord comes in, or near the transformer there should be a small fuse in a holder. It is not a glass fuse and should be replaced with the same kind which is a ceramic, and the same value which is in amps. This is important for future protection.
You can get the fuse at http://www.mcmelectronics.com/ or http://www.repairclinic.com . Get a box of five for future problems. If this was the only problem your microwave should work.
If the new fuse blows you could have a shorted power transformer, bad high voltage diode, or a bad magnatron in that order. There could also be a short in the board with the display but that would be unusual.
