Question about GE Spacemaker JVM1640SJ Microwave Oven
The microwave just started doing this yesterday. the problem starts after about a minute and a half. smells like there is a small electrical short, or like we had put something metal inside and it was causing an arc. the unit is a GE Spacemaker JVM1640WJ01. is this something that i can fix, or should the unit be replaced?
The magnetron inside the microwave is starting to short out to ground. This happens after use there are small minute cracks on the body of the magnetron and those small cracks are big enough for 15,000 volts and up to 30,000 volts to leak through and arc to ground. It is not a small short but a big one. Replace the magnetron before it burns holes inside your microwave. Replacing the magnetron if you can find it locally or through the internet is pretty straightforward. Unplug the microwave and take the cover off about 6 screws. On the same side as the control panel and right behind it you will find the microwave on top. It is held in place with only three to four big screws. It will have about 4 wires with terminals on them that plug into a couple of places one being the large capacitor that stores all the voltage and discharges it through the magnetron. Take the terminals off and I always recommend with some needle nose pliers with insulated handles. There is nothing to unsolder and to solder. Its like replacing the battery in your car or the electronic module. Take care and good luck.

If it blows the fuse as soon as you hit the START button, it's almost certainly a shorted high-voltage capacitor.
If it blows a few seconds after you hit the START button, it's probably the high-voltage transformer. You'll possibly also smell a faint electrical burning smell from the rear vent after you shut if off.
Microwave can be very dangerous so it is best to have it looked by a professional
Would appreciate a solved rating for expert advise.
