Question about GE JE1860 Microwave Oven
How can i open the back door & check what is going on
You cannot operate a microwave with door open because the radiation from magnetron is very dangerous for your health.
Regarding general microwave troubleshooting , see my solution below:
Test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Usually this is a problem with the door switches or a broken door switch mount.
Sometimes after a part replacement one will find a couple of wires have been reversed.
There should be a mini-manual with wiring diagram inside the oven behind the control panel.
If those are all correct, you may have a problem with the control panel, which we repair nationwide for $39.95.
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
