It's probably an issue with the bottom door switch, or its mount. It's a pretty easy DIY fix. Feel free to e-mail me via my site, and include your full model number (or even better, a picture of the model tag) and include your detailed symptoms to let me know what's happening or not happening, and when it happens. - Ed Miller http://www.microwavecontrol.com

Did you check the turn table on off switch on the main control board......Or the board could be the problem.
