I have a black & silver model West Bend Microwave oven that started messing up yesterday. After the time runs out, and door is opened the circle tray in the bottom on the inside continues to still run constantly and does not stop spinning like its supposed to. Any suggestions??

SOURCE: microwave runs constantly

If it's less than a year old, it's under warranty and you should call the nearest Sears store for free repairs. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. 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 full model number here: http://www3.sears.com (the 3 is correct)

I suggest you check and/or replace the door interlock switches.
Hopr this helps.

SOURCE: troubleshooting- microwave turntable and fan run constantly when door closed, door switches test good, timer can be set and oven runs otherwise; need amana microwave ACM1580AS wiring diagram

I'd look for a defective relay or shorted triac on the control panel circuit board. Either could cause this problem.
