Question about GE Spacemaker JVM1640SJ Microwave Oven
F3 on a GE / Hotpoint
microwave means you have a shorted membrane keypad.
If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.
So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.
If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.
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.
If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.
But please note that for some GE models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.
In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.
Either way, we can let you know what your options and costs would be and send you other helpful info.
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.
Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
