Tip & How-To about Computers & Internet
Your unit is dead, mains are good, tried power plug in other receptacles, still no power. You 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. Sometimes they 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 (ceramic) and value. This is important for future protection. You can get the fuse at www.mcmelectronics.com . Get a box of five for future problems. If this was the only problem your microwave should work. If it blows the new fuse 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.
