Ge spacemaker microwave won't heat... - GE Spacemaker JVM1640SJ Microwave Oven

SOURCE: GE SpaceMaker Microwave suddenly stops while heating

I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!

check conrol circuit, and magnetron, and highvoltage section,

SOURCE: Removal of GE Spacemaker Microwave oven

1. Unplug the microwave. The plug is probably in a receptacle that is in the cabinet above the microwave, or in the wall above the shelf that is above the microwave.

2. Remove the two (or three) screws that go straight down through the bottom of the cabinet, or the shelf, into the top of the microwave. Have help in holding the microwave when you do this, as the front of the microwave will be able to fall down when the screws are removed.

3. Allow the front of the microwave to rotate down a little, then lift the back of the unit up about 1/2" to 1". At this point, the microwave will be disconnected from the mounting plate on the wall, so you can move it forward and carry it away.

Mmmm it's so easy,
First disconect the power, take the cover off, moslitly there would be 5 screws and two tab's on the top.
inside on the right hand side the magnetron it's a sylver box measuring about 4 in x 4 in x 5 in. It will have a plasic cover moslitly that would have to be remove first then on the magnetron there is 4 crews and one connector.
It should fall downard after.
If you have a power supply after the secondary , that may also be your problem.

You may have a failure of the H.V. rectifier. I would recommend that a trained technician replace this part due to the high voltage potential.
