I have a Jenn Air Wall Oven/Microwave (jmw3430ws02). The touch screen went out recently. The light inside the microwave comes on when the door is opened, but the light inside the oven does not.

So it's dead? (No display, no inside lights, no beeps?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

    No power in the microwave. It is as if you unplugged it. Is there an internal fuse in the unit? There is power to the unit. The unit shows nothing on the panel and when you open the door, no light comes...

    If you look at the back of the oven there are usually small fuses or breakers back there. Check to see if that is the issue. Also if you haven't already make sure the wall outlet is functional.

    Jenn-air microwave JMC 7000 ADB has no power

    I have a different Jenn-Air built in microwave & oven combination but I'm sure my solution will work for you as well.

    My microwave was plugged into an outlet located on the top of the oven. This outlet has a "circuit breaker" that tripped while we were using the self cleaning feature on the oven. You just need to reset the breaker button right next to the wall oven outlet. Why it tripped is a mystery since the microwave was not in use at the time. Bad design.

    Of course, getting to the reset button is your only challenge. You need to pull the microwave and oven out of the wall/cabinetry in order to get to it. The unit is heavy so you will need help. Or, call a certified repairman and they should be able to do this for you in 30 minutes or less so the service call should not run you more than @$85 if it is no longer under warranty.

    I would also suggest you contact Jenn-Air to complain about this issue and seek reimbursement from them if necessary.
