It's usually a bad door switch or a broken door switch mount. Once in a while it's due to a board problem. 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

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Good Morning,
Unplug the oven and wait 3 minutes then plugit back in and check to see that it operates normally. Do not run the oven empty - place a cup of water in it. Let me know if this helps and thank you for using FixYa!

Test the high voltage capacitor,the rectifier diode.or the magnetron.
If it additionally does not spin and no light, then check also the door switch.
The diode and capacitors can br tested. The capacitor must be alloweddischarge before testing, or you risk to get electrocuted, even ifpower is off. Capacitors can get discharged by shorting their twocontacts.
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.
