Question about GE Spacemaker JVM1640SJ Microwave Oven

Cutting off and on

Hi...this microwave has been a lot of problem. So far 2 new magnetrons. Now it starts to heat, runs about 30 seconds and stops. Everything is off, the light, the fan. Nothing works. We unplug it and it will start again..same problem.Stops dead. Also the turntable will not turn. When we push the turntable button..it says "turntable will not work when probe is inserted". We have NEVER used the probe. Cannot even find it.
Could it be the fuse??? LAst house call..magnetron covered under warranty but labor was $150.
HELP

Sadly, we hear of this over and over.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit.

If a technician just replaces the magnetron and not the kit, the problem can recur.

It can also happen again if the technician used an old style defective magnetron from his stock that he thought was good to use!

GE Customer Service is here. I'd contact them, and I'd check to see if the servicer saw the bulletin and if he used a NEW style replacement magnetron!

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

My microwave stopped working one day. A few times before it completely stopped working, the magnetron would pulse and then shut off. Now the only time it does that is when nothing is in the microwave. If...


If this is an older oven, or an oven that has heated a lot of popcorn, or other low water content foods, then you might be looking at a magnetron that has become intermittent. The symptoms you describe, however, do not match the symptoms you usually see with this type of failure.

Based on your description of the problem, I'd investigate the possibility of an intermittent power relay. The contacts on these eventually burn and sometimes don't make a good connection. After the contacts first close, there're is an initial surge of current that might make the relay functional for a second or two, and then the damaged contacts no longer make contact.

The thermal fuse may be defective, monitors temperature of the magnetron, or the internal fan may not be operating properly, it is possible the magnetron may have a shorted winding.

I have a GE Spacemaker and it is about 9 yrs. old. Sometines it heats; other times it doesn't. I change settings and sometimes that works. Is this something that can be repaired or is this a sign I need...


When the microwave is not heating, that means the magnetron is not working. This is what provides the heat to the microwave. I do believe the magnetron has a 10 year warranty.

If you wish to replace it, here is how:

  1. Unplug Microwave at least few hours before
  2. Remove Microwave from above oven range by somebody holding Microwave from ground unscrew the screws from cabinet
  3. Remove top cover of Microwave
  4. Make sure to keep screws correctly in a place you remember what goes where
  5. Make sure capacitor is discharged, GE manual inside Microwave says capacitor will discharge within 30 seconds once it is off. As a precaution check the voltage in capacitor to make sure there is no electricity
  6. Remove other panels around magnetron part
  7. You need to remove lot of connecting wires, should be careful to note down what goes where
  8. If possible take digital photos to refer back when you put everything back together
  9. You may need to remove transformer to easily remove and replace Magnetron. If you can't remove Magnetron easily then remove bottom panel of the Microwave and remove transformer
  10. Now it should be easy to remove magnetron
  11. Replace new magnetron and screw it. We had to put one outside part from old magnetron to new one because new one was missing that. Check to make sure both old and new one are exactly the same
  12. Make sure put all wires properly back
  13. Now put transformer back and screw it
  14. Put capacitor panel in place and screw it
  15. This might be a good time to test the Microwave to make sure it works fine now
  16. Now cover the top panels and start to screw everything
  17. Once everything assembled put the Microwave back above range put screws from top

H98 error message. Micowave not heating, stops after 37 seconds


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Microwave does not heat.


HI, this is an inverter board issue. the magnetron would not shut down the unit. if the magnetron was the issue, it would continue to run but, it would not heat.

replace the inverter asap.

Sounds like the Magnetron may have collapsed. Probably not worth repairing. Check for burnt/browned components on circuit board/s. Burnt wires, insect or ant damage or soiling. Magnetron is the large-ish square metal object with lots of heat-sink fins on it. Check for discolouration. If nothing obvious, it's probably stuffed, If something is obvious, it's still stuffed, but it may be repairable.:::Spiceweasel.au
