GE Sensor Microwave JES1855 died

You probably just have a bad humidity sensor (aka gas sensor).Also be sure the internal cooling fan is running. That's critical.
We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.
To access and replace the sensor, you may need 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 find handy exploded views and order parts by model number here.
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.

HELLO.

This is the solution to reset your microwave.

1 Pressing the clock button will display the time. You can also use this to know what time it is while cooking.

1. Set the clock by pressing the "Clock" button.

2. Turning the dial on the GE sensor microwave oven will display the hour of the day. Once you have found the correct hour, press the dial in.

3. Again, turn the dial to set the minutes of the day. When this is completed, you will need to press the dial in again on the GE sensor microwave oven.

4. When the time and minutes are set, turn the dial again for a.m. or p.m. Then you will need to press the dial in to save the settings.

5. Press the "Start" button to allow the clock to begin on the GE sensor microwave oven.

Thanks.

check magnetron related circuit and replace magneron, check condencer, diode and etc.,

It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.

There shoudl be a "mini-manual" (tech sheet) inside the oven. The most common reasons for this are the magnetron thermal cutout and the fuse. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383
