Question about Whirlpool MH3185XP Microwave Oven
In these models, there are several fuses and two or three thermal cutouts / thermostats which need to be checked.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden 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 you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your full model number from the label on your oven).
Accessing some components for testing and possible replacement will require you to remove the oven from the wall.
If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
You can download owner's manuals and installation instructions for several brands (including Amana, Frigidaire, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
