I could have been more specific with a model number, but if this general answer doesn't do the trick, feel free to contact me with your full model and specific symptoms here.

It's usually a bad door switch or door switch mount. My helpful text file on door switches is here.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If it's one of those overdesigned Whirlpools, it can be one of many components. See the example photo at the bottom of this reply.
