GE microwave JVM1851WD001, buzzes if you open the door, buzzes if you push any buttons but will not start. The light is on if you open the door and the digital clock is working.

You might have a bad door switch, open thermal protector, or the latch mechanism is not activating the switches properly.

Check the circuit board.

Could be the magnetron or the transformer. No it is not worth repai

That's a defective electrolytic capacitor on the control circuit board.

The fan could have an obstuction. I have heard of tech sheets getting into the fan and causing a vibration and vibrating sound.

My microwave was totally dead. Things I discovered: 1) There is an easily replacable fuse accessed by taking off the top front vent cover (two screws on top, gently massage off) and then the inside plastic grill. UNPLUG before doing this! 2) Pop off two wires on either end of fuse holder for safety. Then pop out fuse and replace. For more extensive help, there is an evelope with a wiring diagram inside the case on the inside wall! Very helpful when diagnosing the surface lamp problem (I forgot to plug the ballast back in when I closed up the bottom).

The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.

This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.

If the top is open, the upper door switch should be open and the high voltage section should not be energized. That's the way it's *supposed* to work. But that buzzing is worrysome! Does the turntable turn during this condition? Does the inside light come on? How about the fan? If not, then I would doubt that it's cooking. If so, some models will do this. It's not uncommon to notice that the fan and light will try to come on for a split second when you shut the door. This would not indicate a problem. It has to do with the timing of the door switches and a replay on the board. If it's still under full warranty, it wouldn't hurt to call a GE-authorized servicer.
