The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

For crazy it may sound humidity could be affecting your unit. Its known the way microwaves work is exciting the water molecules, this creates vapor that will condense in cooler surfaces...well if that happens to be the electronic controls boards or other sensitive components your unit may react doing unexpected things. If it is an space saver oven on top of a range getting all the vapors from whatever is boiling, that adds to it. Also check your unit is connected to a verified grounded outlet. This is critical for the operation and for the longevity of your appliance.

GE JVM130K004 space saver microwave not working

The magnetron is overheating, and the magnetron thermostat is tripping, interrupting power until it cools back down.

This is to protect the magnetron from being destroyed from overheating.

It may be that the internal cooling is not occurring or the magnetron is failing. Cooling can be compromised by:

- failed or failing internal cooling fan
- blocked air inlet or filter
- outer cover not installed correctly

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.


our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find links to helpful exploded view diagrams and part ordering help here.

I'd recommend that your bookmark this link to your favorites.

Ge Microwave space saver over range working but

It is a good possibility that the stirrer has failed. In the top of cabinet is a round cover,there is a small round plug in the edge of it,pry plug out and put it in safe place,rotate the cover < twist locks > gently let it down and stirrer will be either setting on cover or still attached. If you notice any damage< it is a round aluminum disc that is flat > then you need a new one. If you don't see any damage put it back in < put in hole and turn until you feel it line up with shaft and push into place,< gently >.Make note of position and put cover back on < stirrer does not lock on shaft so you have to hold it up until you get cover under it in most cases. Run a short cycle and remove cover to see if it turned at all. If not the motor is bad < turns stirrer during operation>. This is the first time that question has been asked of me and it is the only thing that I can think of if it heats glass and not food.

Code on the space between oven and microwave

It's normally about 30", but that info will be in either the installation manual or the owner's manual, depending on the brand you choose.

You mention SpaceSaver, that's GE.

You can download GE owner's manuals and installation instructions here.

Not heating properly

I have a GE over the range space saver microwave that was only 18 mos. old when it stopped heating. GE replaced the magnetron for us at no charge but since we did not have a service contract - they charged us $200 to install it. It only cost $375 new installed. Your choice.
