With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

The diode is a fairly cheap fix, and the mag will cost more and is more complicated to replace.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)

http://www.gallawa.com/microtech/mag_test.html (continuity can be good even though it is bad!)

There should also 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 usually find helpful exploded view diagrams and order parts by entering your full model number here.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it needs a new magnetron, you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

If you want to contact GE about having an authorized servicer look at it, or have them send you a magnetron, GE Customer Service is here.

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

SOURCE: Problem with the GE Spacemaker (JVM1640SJ)

The magnetron is more than likely the problem, "heats food" cheaper in the long run to replace the microwave oven.

My GE Profile Jvm1870sk03 microwave built oven does not work. There is power, the clock, timer works. If I press the button to heat the clock shows it's going on but there is no heating process go


Most likely door switches. Companies these days use switches with small 3/16 terminals and they tend to get hot and make the switch go bad. When I replace them I put in a 20 amp rated switch with 1/4 inch terminals, and a short section of better wire to the switch. If you make better connections it stops the wires from getting hot and the switch will last a long time.

You should first be sure your filters are clean and that your ductwork is clear.

See this link for a bulletin that may address your problem.

Otherwise, see this link in case you have a sticky door switch or relay.

Problem with the GE Spacemaker (JVM1640SJ) Microwave Oven GE Spacemaker XL1800 won't heat food anymore....It worked this morning, now won't heat. What should I do?


GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.

Doesn't heat up food


Hi


Thanks for using FixYa. Microwave not heating properly is caused by a power relay going bad, cold solder joint on the board and/or magnetron (this is only if it makes a loud hum/buzz sound). Also the door hooks and the door-release button should be checked. Please do rate the solution if the issue is resolved or post a comment for further assistance.



Thanks

the magnetron needs replacement my friend, although you can still heat up food but eventually it will soon fail.
