Question about GE Spacemaker JVM1640SJ Microwave Oven
If you can program the time but it
will not start cooking when you press the "Start" pad, you probably
have a bad door switch or door switch mount.
If the oven has no display and will not respond, it is "dead" ands it may have a blown fuse or a blown magnetron thermal cutout (TCO) or thermostat or a blown oven cavity TCO or thermostat.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
Accessing some components (especially an oven cavity TCO / thermostat) for testing and possible replacement will require you to remove the oven from the wall.
If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
You can download GE owner's manuals and installation instructions here.
