I have a Jenn-Air JMC7000ADW Microwave / Oven in wall combo that is 9 years old. My microwave stopped working last night. The oven still works. Do you think this is easily fixed? Thanks,

    My Jenn Air JMC7000 Microwave is completely dead, its 8 years old, we had this same problem occur a couple of years ago. We called the service guy and he indicated there was a "reset button" that he pushed and made it work again. He told us it was under the microwave - we can't seem to find it - is there a reset button?

    It just went dead...and has not come back on. No lights, nothing on the control pad. I heard it cost $189 to replace the control pad. Is there a reset button. Our unit is in the wall with an oven below it. Thanks for the advice.

    While cleaning the oven I started the jmc7000 and it went dead. Is there a reset button? If so where is it located?

    My microwave went dead on Nov 23rd. The control panel is still it, the clock and timer still work, the light comes on, but when you hit the start button nothing happens. The timer starts counting down the time, but the microwave never turns on. Any advice on what is wrong with it would be much appreciated.

    My JennAir quit working on Nov 23rd. The control panel still works. The time is displayed and you can select a cook time but the microwave never comes on when you hit the start button. The timer begins counting down the time and the light comes on, but nothing happens. Any advice would be much appreciated. Thanks

    I had the same problem around the same time. This happened once before 2 years back when I called the service technician who replace just the fuse and it worked. So this time I tried opening and replacing the fuse in the fuse holder. When I plug back I saw sparks on the plug. No life on the microwave. I tried replacing the fuse with a new one and tried. Same story. I guess there is some other issue. Now I may have to call the service person. Any other way to diagnose the problem with sparks (I guess fuse blowing out.)?

    Our unit is also part of a double convection oven/microwave and is no more than 5-6 years old.  The microwave simply stopped working yesterday.  The pair still looks brand new!

  • spuddin Sep 15, 2008

    I have the same problem.  7-8 year old unit.  Put something in to cook, walked out of the room, when I came back microwave had no lights, no power.  Flipped all circuit breakers, but microwave doesn't come back on.  Is this something that is easy to fix or should I just get a whole new microwave?  Oven unit still works.

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.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya:

    In my 25+ years of experience I don't seem to remember any reset buttons on micorwaves.

    I've occasionally seen them on other devices, but to me the presence of a reset button is a sign of a poor design - as if they expect it to lock up the controls! *grin*

    One good way to do a reset is the hard reset, which you do by unplugging the oven, waiting several seconds or a few minutees, then plugging it back in and trying it again.

    Maybe BigLib got an unscrupulous servicer who wanted to make a fast buck with a hard reset...

    If this reset doesn't fix it, please go back and carefully review my previous reply.

    Happy to help.



.. there is a circuit breaker under the micowave, on top of the oven, on the right hand side. remove the plastic faering (4 small screws, two on each side) and look in with a flashlight. sometimes you can simple click it "like a switch" and that fixes the dead microwave ....

.... other times it is a good deal more serious

How can i disassemble a jmc7000adw

Although most open via a screw at the top or left side of the control panel.
Some require the cabinet / casing to be removed. If there is no visible screws at the top or sides of the control panel. Then the casing will need to be removed.

JennAir JMC7000ADW Microwave Oven Not Heating Well

Assuming the turntable is working and the power at the outlet is correct (110 to 125VAC) then you almost certainly have a failing magnetron.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first: (continuity can be good even though it is bad!)

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also 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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

JMC7000ADW Blows circuit breaker

I've had this problem twice with our microwave. The hint to where the problem lies is that the breaker blows when you open the door at times. Inside the microwave are three microswitches; primary and secondary interlock micro switches and an Interlock Monitor switch. The switches are supposed to shut down the microwave if it is running and the door is opened. But, I've found the upper primary switch can stick internal at times and when the door is opened the stuck switch will, because of the way it is wired as a safety switch, cause either the fuse or possibly the main circuit breaker for the oven to pop. The reason the stuck switch blows the breaker or fuse is when the door is opened the interlock switch will cause the neutral wire from the AC power to be applied to the Upper Primary Interlock switch which normally should be open when the door is opened, but if the switch is intermittent or the contacts weld themselves shut the neutral line is connected direct to the "hot" side of the power line through the fuse and thermostat. The first time my microwave failed the switch had melted the contacts together inside the switch and the second time the switch became intermittent and would blow the breaker to the over ever so often. I suspected the switch the second time this happened and utilizing an ohm meter I checked the switch several times by opening and closing the door and once in a while it would remain closed instead of opening when the door was opened. Of course while trouble shooting the power cord to the microwave must be disconnected and use all safety precautions when working around the high voltage areas inside the microwave. I wrote Jenn-Air about the bad switch and the way it is wired into the circuit, but never received any acknowledgement. I suspect these microswitches are under rated for the amount of current that passes through the switch, thus they overheat and eventually arc the contacts together. I hope this helps explain the intermittent problem and could explain many of the intermittent blown fuse problems I see in these internet help sessions

Microwave turntable won't turn

You will have to take it out and then take off the outer cover to expose the drive system for the turntable unless the items turns with the turntable removed. If it does then (and if it is belt driven) the belt may be worn and slipping. Anyway you look at it the cover has to come off to see what is happening.
