I highly suggest you look over on google for a Ytube post under metacafe.com for microwave repair, , a professional repair man will take you through the paces of diagnosing a microwave safely, seeing is believing. I suspect your problem is with one of the several microswitches that are usually easy to access and don't require touching anything dangerous, and can cost only a few dollars to replace. This site can link you to parts houses that have model specific parts, the only downside is that they don't have schematics, those appear to be locked up by people who sell service manuals that carry the schematics, so you really need to do as much of your own research as possible. There are other links to sites that carry a troubleshooting list. They state "switches are 75% of the all the problems" people have. Here is a good one: http://www.repairfaq.org/sam/micfaq.htm#micintrlk

I sincerely hope this helps you help yourself, good luck !

Something in the door is causing microwave to shutoff. Sensor is on, but then shuts down unless,also you hold a certain pushing in the button.


Adjust the latch switch assembly to make sure that the door hooks engage with the switches. Loosen the 2 phillip screws holding the assembly and slide back and forth to adt. Retighten when the door hooks are making solid contact with the switches.
