Question about GE Spacemaker JVM1640SJ Microwave Oven
Just moved into a house with a GE spacemaker and the buttons are nearly unresponsive. Pressing "time cook" doesn't do anything. The only buttons that work and only occasionally are the express 1 minute, 5 minute buttons. The only way they will sometimes work is periodically unplugging the microwave and resetting it. Please help
> model JVM1640WJ03
The keypad is part number WB27X10721 MEMBRANE KEY PANEL available for $37.09 here (it's $61.50 from GE!).
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.
First of all, you should check the end of the keypad strip for rough white, gray, or green deposits that can sometime interfere with conductivity.
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.
Then disconnect the strip as shown in the photo below and use a soft pencil eraser to gently clean both sides of the end, then reinsert it and try it again.
If that doesn't fix it, and you don't notice any rough white, gray, or green deposits on the circuit board (moisture or mineral deposits) or grease, then your keypad is bad.
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.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
If you would like to have us do this repair for you, we do that for $39.95 plus part costs.
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.
