Question about GE JVM1860 Microwave Oven

1 Answer

Buzzing sound when the vent fan is turned on. Sound is high pitched, and I can't tell if it's coming from the top or bottom. Any suggestions?

    Looking at the assembly drawing, there is a fan (item 53) and a blower (item 59). When does one run versus the other? Right now, the noise does not occur when the unit is turned on and heating food, but the noise does occur when the vent fan button is pushed. Next I'll need advice on how to get access to the noisy part to either inspect/lubricate and/or replace it.

I don't know if this applies in your case but I have had fans with metal blades that would resonate with a high pitched ringing sound. It may also be that a blade is slightly contacting a metalic mesh filter cartridge.

Sounds like a problem in the high voltage side. Need to check the diode and if good the voltage at the magnetron. Should be 3.5 volts across mag and 4500 dc volts at mag. If you do not have a meter to check replace both mag and diode aprox $150.00 from GE. Pat

The high pitch sound to me may be coming from the speaker on the main circuit board. Try to unplug for a few minutes, reset clock time and then try again. If same issue, may need new PC board. When you say Microwave continues to run are you meaning the Turntable is turning and the fan running?? Or is it just timing down. Almost never does it actually keep heating. On GE units I mostly find bad door switches will cause a back feed and make the tray turn and the cooling fan for the mag to run. To see if that is the problem You have to look at the door switches behind the front panel on the left side and see if any of them have any browned connections on the terminals where they push ontl the back of the switch. That will cause the fan and turntable toi run, but wouldnt cause a high pitch squeal. These companies use switches wtih small 3/16 terminals that dont give a good enough grab on the switch, they get loose and hot and make the switch go bad. I replace that switch with a switch with 1/4 inch terminals and runa short section of Hi temp wite to it and it wont go bad again. Just cheaply made!! Also I guess the squeal could come from the turntable motor area. So By fixing the switch problem it could fix your squeal. With nothing else running you may be able to hear motor and coupling noise you couldnt hear before.

Works - but the sound has changed


Possibly, the "fault" was the buzzing in the first place! Buzzing is usually a cabinet vibration caused by magnetic fields from the "gubbins". If the buzzing should occur again, try pushing/ pulling/ poking the cabinet while the oven is running, you may find a position that causes the buzz to stop.
Another possibility is you previously had something else placed in close proximity to the oven.
If a rattling cabinet is the problem, either try to reposition something, or just ignore it!

Buzzing noise, wont work???


The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.

Constant Humm / Buzz but Works OK


I was going to suggest the low voltage transformer, but when you said it sounded like it was coming from the left side, that seemed odd. I have a stock transformer here I keep for test that is loud, but it works. Odd, eh?

High pitched hum/buzz


By high-pitched, you mean it is not that same frequency as when it's cooking? Is the tone near or the same as the beep you hear when you press a key? Please post a little more information so we can help better.
