Short of buying the service manual, you can find helpful exploded view diagrams by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Replacing the magnetron will require the removal of a lot of screws. Keep track of where they all go.

We have critical safety information at our site, and our link is at our listing here on FixYa.

My GE model JVM1631WB002 is giving off a burning smell. What can I do?


A burning smell is usually a sign of a bad magnetron tube, the microwave source. As they age they take more power, and this causes excess heating that can cause the smell. Eventually the tube burns out and you get no heating. If you've been noticing longer than normal cooking times, it's due to the weak tube.

You can replace a magnetron, but it's a costly part (around $100-$125) and the repair should be done by a professional because of safety concerns. (Several websites describe how to replace a magnetron if you'd like to try it yourself, but you need to be very careful. MICROWAVES USE HAZARDOUS VOLTAGES WHICH CAN KILL YOU.) Between the part and labor costs, when the magnetron goes bad it's often more economical to spend a little more and replace the oven.

There are some other parts that can get hot and sometimes smell, but the magnetron is most common. If you want to keep the oven, I'd suggest letting a professional check it over and give you an estimated for the repair. Then you can decide what you want to do.

Won't heat any foods.


you have a problem with your magnetron tube, and when the magnetron tube goes bad, the diode almost always goes out with it. you should be able to order a replacement tube from your manufacturers website, if you cant let me know and ill try to help you more.

here are the steps to replace the magnetron tube, if you want to do it yourself that is. if you have a professional do it, it can be pretty costly.
  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

Evry thing works except the food is not heated. It makes the noise, timer counts down..


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 of the blower housing, or magnetron tube assembly)))

Microwave does not heat


Sounds like the magnetron has failed. This is the component that produces the microwave that heats the food. The cost of the magnetron is about 95% of the cost of a microwave . Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing. There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

GE JVM1650 Microwave Suddenly Stops


Tami,
It isn't really difficult to replace... It's the 4000 Volts that go to it and the stored energy (voltage) in the high voltage capacitor that concerns me as far as telling you that it is a do it yourself repair. Also, and this a huge concern, is that after the magnetron tube is replaced, the microwave should be leak checked. A microwave leak detector that is certified is around $400. Now that I said that, I have rarely ever had one that leaked, but it is the law and that's the main reason that it needs to be done. I highly recommend calling GE Factory Service 1-800-432-2737 (1-800-GE Cares) to install the magnetron tube.
