SOURCE: Microwave oven was very hot and shut down with blank display.

For future reference, I always recommend that you turn on the microwave's hood vent exhaust fan whenever you're cooking on the stovetop or oven.

Depending on the brand and model, there will be either a thermal cutout or thermostat on or near the magnetron. There is also one on top of the oven chassis ceiling, but under the outer cover.

Either device may have opened.

In many brands there is 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.

Accessing some components (especially the oven cavity thermostat / thermal cutout) 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.

Hello, welcome to FixYa.

I understand you have a Jenn Air over the range (OTR) microwave, correct ? I can tell you on most microwaves with these symptoms you're dealing with a bad control or a faulty secondary switch, (if you check your diagram you should see three or more door switches...typically 3).

Before going too far though, if you could double check the model number and confirm it is indeed JennAir, I'd be better equipped and most certainly able to help without generalizing...the info above appears to be only partial.

Also anything further you can add will help in a speedy solution. Can you elaborate on what you've done to "check the lock" ? Does the unit make any sound when the start is pressed ? A click ? Or do the digits in the display just count down without any other function...other than what you stated regarding the interior light ?

I can guide you on accessing these switches, controls etc. or changing them, but I'll need to clarify the model as I mentioned before going forward.

I will watch for your post and I'll continue to help in any manner I can. Good luck

Regards,

Macmarkus :)
