Question about GE Spacemaker JVM1640SJ Microwave Oven
In most cases, this is a bad door switch, but it may possibly be a worn out Start pad on your keypad.
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.
I would suggest you or a friend use this to check the door switches and mounts.
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.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
If you only need a switch, you can order a universal type here for $5 postpaid.
If it's not the switches & mounts, check all the keypad pads and see if any others are not working.
You may have a failed keypad.
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.
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 model number) for more information & help.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
