Question about GE JES1142SJ Microwave Oven

Microwave won't heat, and turntable doesn't turn

I have a GE microwave oven that won't heat, turntable doesn't turn, but the display works and timer counts down. Makes a little click sound when you push start.

    Model # of micro is GE JES1142SJ. After researching I found it could be lower door switch, faulty relay, or triac. Sounds like it's time to get a new one.

All the parts you mention are very inexpensive, but yours does not have a triac.

It could be the cook relay, but it's more likely to be a switch.

Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you have a broken mount, it's usually more economical and safer to just add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

There may also be a "mini-manual" hidden inside the unit behind the control panel or elsewhere, which is very helpful when troubleshooting & testing.

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.

If you only need a switch, you can order a universal type here for $5 postpaid.

No heating, turntable does not turn, but clock & lights work.


Check to make sure the plastic on the shelve holders or tuntable guide did not wear and expose metal. If these holders or brackets are wore and exposed metal it shorted out your micro wave. They need to be replaced and a fuse needs to be replaced inside the control panel,

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
