Need xl-1800 manual - GE Spacemaker JVM1640SJ Microwave Oven

probably fryed the magnetron, with something like foil or metallic, try unplugging it for 12 hours maybe it will reset if not throw it out

I'm betting your base model number is JVM1860, JVM1861, JVM1870, JVM1871, JVM3660, or JVM3670.
That's the automatic louver you're having trouble with. There are micro switches in the louver assembly which tell the controller when the louver is open or closed.
If one of those switches or the louver motor fails, the louver will not work correctly.
Did your cooktop lights recently fail?
Sometimes the surge from them shorting will cause damage to the circuit board, which can be repaired.
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.
There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

check fuse inside unit microwave has a fuse around 15 to 25 amps get at local hard ware store u should discharge capacitor before installing fuse not nessary in microwave

Hello ,

My husdand broke our plate. Did you find one yet at a resonable price? If so email me at [email protected] and let me know how much you paid for it.If not you can call GE at 1-866-540-2797 and they will transfer you to the parts department and then you can order a new one. I just called ther but the parts department was closed. So call there M-F 8am-9pm.Good luck!

I had the same problem. You need to replace the turntable motor. I used a local appliance repair shop and they charged $45 for the motor plus $65 labor(a house call). I just checked with searspartsdirect.com and they have the motor(part # WB26X10038) for $22.27. Oh well, at least it works.

if there is no plate to unscrew in front of the bulb , then the only way it can be changed is to open the microwave
WARNING: HIGH VOLTAGE CAPACITOR INSIDE WILL STILL BE HOLDING HIGH VOLTAGE
if you are not familiar with this then don't attempt the repair!
then you will need a technician
