SOURCE: Where is the fuse?

It won't be the fuse. If the fuse were out, it would be completely dead.

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

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

SOURCE: everything works except the cooking part/no heating/turntable not turning, help!

PRELIMINARY REPLY

This is just a preliminary reply. We will need more information to help you.

So you're saying you can set the cooking time but when you press Start it won't start?

If this is the case, you probably have a bad door swithc or door switch mount.

Please reply back with more detail so we can help you.

SOURCE: Everything works...Except for actually heating the food

It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.

SOURCE: My Frigidaire over the stove microwave not heating food

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.

SOURCE: Microwave just stopped cooking!

The simplies is the fuse, which is located inside the unit, you need a screwdriver to open it

SOURCE: frigidaire microwave stopped heating

The problem of not heating is most likely the door interlock switch. The 'primary' one goes bad the most often. On some microwaves all the interlock switches are in a cluster and must be replaced together and on other microwaves the switches are individual micro switches.

Microwave stopped heating up the food. Everything works except for the heating mechanism.


Check the door safety interlock switches. Remove the cover to find these small micro switches on the side away from the hinges.

Everything appears to work fine but it is not heating anymore.


If the microwave oven appears to be working but it is not heating the food, it is very possible that the magnetron, or its power supply has failed.

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

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

MICROWAVE NOT HEATING


I have the same problem. Everything seems to work except it doesn't heat up food.
I remember last time when it was working. I pressed the start botton before I closed the door. So it didn't start automatically, and I pushed start and it worked(it still heat up the food), but it doesn't work now. Help Please!!!
I have a Whirlpool Gold GH5184XPQ.

Thanks in advance

Microwave not heating up


that has happened to me twice, the only thing that you can try is to change the setting to make sure that its not on DEFROST setting, and if this is fine, they I recommend U to get a new Microwave. :)
