How to fix a dead microwave.

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.

My jmc7000 jenn-air blew a circuit breaker. No power to the unit. There is power to the recepticle. I'm wondering if it blew a circuit breaker, does that mean the problem is most likely a big problem and I maybe better off replacing the unit, or is that not necessarily a big deal just because it blew a breaker. Any idea if I should replace or repair? The unit is 10 years old. Thanks


Yau say a few conflicting things. First you wonder if it blew a breaker, and then say you have power to the receptacle. If you have poer to your receptacle your breaker if not tripped. There are NO breakers Inside of the Microwave. Only 1 time fuses. So, if your init is dead it has probably blown a fuse inside of the unit. If that is the case. Probably shorted HIgh volt capacitor would be my first guess. If it is jsut dead. it can be other things than just a blown fuse. bad thermal protectors, bad low voltage transformer on main circuit board. Burnt wires. Anything that will cause it to lose power inside the unit. From bad parts to bad connections.

No lights - no power - DEAD! Worked fine an hour earlier now ... nothing. Check fuse in mains box - all OK - tried it plugged into another outlet... nothing.
