The dial on our GE JVM1790WK01 microwave turns freely but does nothing. I checked the knob for damage, none found and the shaft turns freely with a slight bump as it goes around, but does nothing.


turntable problem? it's probably the motor itself. it's easily removed under the bottom panel. you'll need the pricey ge orig. part; as they use a odd 21volt motor. good luck.

I have a GE microwave model JVM1851SH06 that is completly dead. I replaced the Fuse and power came back, but 30 sec in it was dead again. What should do next.


You need to first verify that your outlet is correct at 105 to 125 volts AC.

If so, then you may have a failing high voltage transformer (rare) or possibly a failing magnetron, etc.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/cap_test.html

http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)

Ge advantium 120 microwave oven completely dead


You have a bad cavity switch. I would guess it is the one behind the vent cover, toward the left side of unit. You would need to remove unit from wall. Remove outer housing to expose cavity switch. You can see it from vent cover, I would test all cavity switches before removing from wall. You should have a diagram of unit folded up behind vent cover towards right side of unit. This tells all workings of unit. Will also tell where all cavity switches are.

Ge jvm1650 microwave oven totally inoperative.


There will be a fuse, a cavity TCO (thermal cutout/thermostat) and a magnetron TCO.

These are the parts to check.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You can find helpful exploded view diagrams and order parts by entering your full model number here. (Don't forget the suffix).

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
