Microwave not heating

My GE model JEB31BF001 microwave acts normally in every way except it is not heating. I checked the main 15A fuse,and both door interlock switches with no problems found there. The HV diode is showing an open circuit. Would this keep my microwave from heating? Thanks for any help given, Craig

If the microwave operates normally, but does not heath at all, then it can be the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, your model number did not return any result, contact the seller here to purchase parts. (here in UK).

Troubleshooting Ge Microwave that is acting bizarrely


Sounds like the main control board, but further testing should be done to rule out other possible causes. One thing I would do is to check to make sure it is plugged into a grounded outlet that is actually grounded. Bizarre behavior can be caused on some ovens because of a lack of a ground connection.

GE Spacemaker 1400 acts like everything works but does not heat.


Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck

GE profile spacemaker model JVM166OCB007 not heating anything.


Does it make any extra sounds that it didn't use to? This would indicate something shorted in the high voltage doubleing section. If not, probably a bad magnetron or door switch.

Everything works except heat


Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron

Everything works except it doesn't heat anything


no, just 1 main fuse for everything. there are temp safety devices though, and door closed safety switches. Most likely failure though is the magnatron.

GE JVM1190 microwave oven light comes on, but no the FAN or "microwaves"


If it were just just not cooking, I would suspect the magentron. But since the fan is also not working, I think you have a bad door switch. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, as well as other specific troubleshooting information and help. In my professional opinion, no one should work on a microwave unless they are fully informed and aware of the deadly hazards and necessary precautions. You can find safety and disassembly text files (as well as a text file which helps in diagnosing and repairing door switch problems) at http://www.microwavedisplay.com You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383
