Question about GE JVM1440 Microwave Oven
I have a GE Spacemaker XL1400 (purchased on 1998). It runs but does not heat. The last work run was on Sunday (12/21) after I made some popcorn. I have not heard any abnormal nosie, and the table seems to turn normally. Should I have it fixed, or it is time to get a new one? Thanks.
Thank you for a well-detailed request.
With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.
The diode is a fairly cheap fix, and the mag will cost more.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
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.
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.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted, it's probably okay)
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
