GE Microwave won't heat

GE Microwave over the oven won’t heat. What is the problem and is it worth the fix or should I just buy a new one. This is an over the oven spacesaver.:mad:

Everything appears to work, display and interior light. When I do try to cook something though the microwave gives off a burning smell, food remains cold. Thanks for the information.

[COLOR=#333333]There all kinds of possibilities, I’ll just list a few.[/COLOR]

[COLOR=#333333]Burnt wire connection[/COLOR]

[COLOR=#333333]Bad high voltage components, such[/COLOR]
[COLOR=#333333]as high voltage capacitor or diode.[/COLOR]
[COLOR=#333333]Any of which could be brought on [/COLOR]
[COLOR=#333333]by a bad magnetron.[/COLOR]

[COLOR=#333333]A bad winding in the transformer.[/COLOR]

[COLOR=#333333]These are just a few possibilities. [/COLOR]
[COLOR=#333333]Some troubleshooting needs to be done [/COLOR]
[COLOR=#333333]in order to isolate exactly what’s at the root [/COLOR]
[COLOR=#333333]of the problem and determine how severe it is. [/COLOR]

De ja vu. This seems to be a recurring problem. My GE microwave is over 5 years old. Possibly one or more components have a short life span. It seems to be working properly, except that it obviously doesn’t heat (a severe drawback). Since there are no odors or other indicators, is there one or more parts that are likely to be the problem? (coil, or transformer?)

For some reason, the magnetrons GE uses don’t last.
Most likely that is your problem. But a proper diagnosis to eliminate any other possible causes is in order.

I have the same model and the same problem but with a somewhat louder humm than normal. I replaced the magnatrom with no results, no heating.
Can you advise further?

[COLOR=#333333]Chances are you didnt need the mag.[/COLOR]
[COLOR=#333333]You need to check the various components [/COLOR]
[COLOR=#333333]such as HV diode and capacitor before purchasing [/COLOR]
[COLOR=#333333]any other parts. One of them may be shorted.[/COLOR]

Thanks Glen–I have further INFO: Touch pad, turntable, fan, lights, all work but it will not heat. It loads up as if it were heating with a somewhat louder humming noise. I have replaced the Magnatron but with no results.(waveguide shows some discoloration from heat). With door closed i have 2 door switches with continuity and 1 without. All heat sensors appear to be working. I checked for continuity of the HV capasitor (two treminals)and got nothing. and on the HV Diode(does not appear to have been hot, nor blowing fuses) and got a reading of 16.6 BOTH ways. Can you suggest a cure? THANKS

Whats the make and model of your meter, and what
type of batteries does it take?

Sounds like the type of microwave that I have. Sounds like the problems I’m having too. No heat, loud buzzing, everything else normal. Any insight as to where I should look for the model number on this thing? I’ve been all over it, and under panels with no luck. They’re usually quite easy to find. Hope it’s not on a data plate that may have come loose and subsequently lost. Thanks…

Seems I have the same microwave. Over the range spacemaker XL 1800.

Everything seems to work fine. Just will NOT heat. I used it last night and have seen no symptoms of problems. It just quit heating.

I had the humming noise too and GE replace something last year.

It cost $80 to have GE come out and look. I just called. Plus parts and labor.

How much could it wind up costing???

model # could be JVM1870SK03

mine is from nov 06

If anyone wants to sell off the turntable plate from one of these non workig microwaves I’ll take it. I will probably wind up getting my no heater fixed, but I broke the plate. What a day…

spacesaver 1800XL

This website wants $50.00 for one!!!

This is the same exact thing that is happening with my spacemaker. It’s over 5 years old. Light works, turntable turns, digital clock works, except it won’t heat. It doesn’t sound like it used to, there is an extra humming sound, but I do remember the night before I was popping popcorn and it sounded like the microwave popped, like when you put something metallic in it. Next morning it wasn’t working anymore. All I want to know is whether I should call me someone to fix it or get a new one? Can someone tell me what it cost them to fix, I won’t be doing this myself I have to call someone in to do this.

I have a good capacitor (940nF). Good transformer primary voltage. Bad diode (~16 Ohms either direction) - just ordered from your site.. Should I replace the diode first and test, or just go ahead and replace the magnatron as well?? Is there a way to test the magnatron independently (without specialized equipment)? I don’t want to short another $35 diode to test.. Thanks in advance!
