It is a very good chance the magnetron has gone out especially if it is making a low pitched hum. There could be a door switch problem but more than likely it is the magnetron.

SOURCE: GE Spacemaker Microwave JVM165OWB005--No more heat!

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

SOURCE: ge microwave won't heat everything else works fine

Hello t_sumner4756,
Everything else can work perfectly fine but if it doesn't generate microwaves to heat your food than it is not working ( you knew that anyway).. Unfortunately, and in most cases when you microwave stops working in that manner..the components at fault are either the Magnetron, Filament PS or a High Voltage Capacitor..What that means is that you are probably better off just replacing the entire appliance rather than attempting to repair it. If it is a year old or less, bring it back to where you purchased it and have them replace it.. I am sure that is not what you wanted to hear but when the cost to repair exceeds the cost to replace... it just isn't worth repairing.. Plus.. there is an element of danger associated with these kinds of repairs...
Regards,
Rick

SOURCE: Everything works except heat

Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron

this is something you should probably call a repair technician for, due to the danger of the componentry.

Usually in ther case of this problem, even a technician will advise you to replace the unit, in the minds of cost effectiveness and safety...

SOURCE: GE spacemaker microwave does not heat food; fine otherwise.

Most likely the hi volt energy components. Usually the hi volt diode or hi volt capacitor. There is hi energy stores here so be careful or do not attempt it. A person skilled in electronics, tv repair, or microwaves can handle it . It is usually worth repairing. The other parts that could be the problem are the magnatron or the hi volt transformer; if so, you might think twice before repair (the price will be higher).Goodluck, Macgivor

GE microwave model JVM1750DM does everything except heat food. Worked this morning fine.


Chances are the magnetron has failed, "heats food" the other possibility is the high voltage capacitor and diode. Repairs will approach the cost of a new microwave oven.

It's a bad magnetron.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

Burning smell and won't heat.


If it buzzes real loud it's probably the high volyage diode. However some times if it smells it's the transformer. Usually the diode is a cheap fix ~$10.00 but this model the diode is $50. It's number 50 on the link below. Let me know how it works out or you need anything else.
