Question about GE JE1640WA/GA Microwave Oven

Oven runs but does not heat

The unit is approx 7 years old. The other day it stopped heating. It runs but does not make the same 'pitch' when turned on. It also makes a smell like electronic burning. Time for a new unit?

Re: Oven runs but does not heat

This is going to be either the high-voltage transformer, the magnetron, or the high-voltage diode. Magnetrons are the mosty common failure in these, and there is a campaign underway to replace "underperforming" magnetrons. To see if yours is one of these, visit:

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old

If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

Oven stopped heating; everything else seems to be working. i dont notice difference in sound when turned on model JVM1642BB 003 man date july 2000

The symptom that you have described sounds like the magnatron has failed, the microwave oven looks to be approx. over 9 years old, at that age and with a failed magnatron it is not cost effective to replace the part, it would be best to replace the microwave oven at this point. Good luck!

GE JVM1440WH01 Will not heat, everything else works. This unit is 6 years old and just stopped heating. The carosel turns, fans work, the timer counts down and lights come on when you start cooking or open...

It could be a number of things, Burnt connections between the magnetron, Capacitor, Diode and transformer, Heater connections loose or burnt, Transformer, Capacitor Diode or Magnetron US. You need to strip it and find out if you are getting about 2000volts to the Mag, Are you getting approx 5volts across the heater terminals?? NOTE that the 2000 Volts can remain in the cap indefinitely and the voltage is LETHAL. IT WILL KILL YOU if you don`t take precautions. Ian

My spacemaker GE 1440 do not heat it 2 years old

Hi tony,

The units magnetron(the device that generates the micro waves) is failed or failing, this can be DIY depending on how mechanically inclined you are.

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it:

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
