Open Question

Dead GE Spacemaker XL microwave oven, model JVM1331

Was just starting to heat something when oven made a hummimg noise & went dead. Checked breaker & power at outlet which is good. Opened unit & found a blown 20A fuse. Replaced fuse & restored power to oven. Lights & fan work. Tried heating something in oven & the same humming sound occurred and fuse blew again. A diagnostic sheet found within oven says to check varistor, but I don't know what it looks like! Also, what are magn TCO & oven cutout? They're next on the troubleshooting flow chart.
TIA!

SOURCE: Ge Spacemaker microwave jvm240 wv Micro hood combo.

sounds to me like the magnatron has shorted out. i don't know of a way to test them unless you have some high dollar equipment. a continuity test prob wont tell you anything. what reading did you get on the cap when you tested it?

It could be a flame sensor, which is a thermal switch located inside the cabinet on top of the cavity (there may be two of them). One power lead should go to the fuse, the other would go to the flame sensor. Remove the flame sensor and check for continuity. If it shows open (infinite resistance), put it in the coldest part of your freezer for a few minutes, then retest. If it now reads continuity (zero resistance), replace it, put the appliance back together, and see if it works.

My microwave went dead while heating up something what could it be


It probably blew the main fuse. Since it blew when it was running, it might indicate that the fuse holder isn't holding the fuse tightly enough; causing it to heat and internally melt.

You also could have some sort of failure, or failing component, in the high voltage circuit.

GE spacemaker XL microwave oven blowing fuse


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the house fuse or breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

Here's a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.

My GE spacemaker microwave won't heat and makes an unusual sound


I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.

Microwave oven does not heat anything. Clock, turntable, lights work. I turned the turntable off while the oven was cooking--heard a noise, now it doesn't heat anything.
