Question about Microwave Ovens

1 Answer

Microwave will not heat

Light go on. Turn-table goes around fine. Everything seems to work. Sound might be slightly louder, but not sure. Only by a little bit if any louder.
Model JVM1642WB002, GE Space Saver. Let me know if this sound like an easy fix with buying some parts. Don't want to spend a lot of time trouble shooting. Manufactured in 1999

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

The diode is a fairly cheap fix, and the mag will cost more.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

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

Noise while not running


don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

GE Spacemaker XL1800 does not heat. All other functions appear to be working normally, the light comes on and the turntable functions. When turned on, it makes a humming noise slightly louder than normal,...


Possible bad heating element, You should remove the cover of the unit and look at the heating element with the power off. Until you get your problem resolved I would recommend not to even turn it on due to the fact that you are unsure what is going on and you smelt some burnt smell. Just for safety until you fine the problem

Everything works but no heating?


With inside light and turntable on, louder sound, and no heat, this is usually a shorted high voltage rectifier diode or a bad magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

GE JVM1440BD Won't Heat


If it making a louder than normal humming or grunting sound when operating, than it's a sure bet it's the MAG.
