Question about Jenn-Air JMC7000 Microwave Oven

Removing a built in Jenn-Air Microwave from it cabinet...

Just bought a house and the built in Jenn-Air Microwave, oven combo unit is on the fritz. I *think* the JMC7000 diode is bad. I want to test it, but removing the microwave from the housing seems challenging.

After taking on the bezel face plate the surrounds the microwave, there appears to be a bunch of brackets that keep the unit inplace. There is no easy access to an screws or anything.

Any ideas? Any links to oven/microwave install instructions, so I can reverse the process?

    Thanks for the reply.

    The symptoms are a loud noise with about half heating capacity. From an earlier poster it has been suggested that this is a diode problem (likely) or could be the magnetron. [Personally, I'm not a fan of Jenn-Air and would buy a replacement - but finding an exact size has proved challenging].

    It is heartening to read that I can access some parts from the front. I'll poke around and look for the screws you are talking about. I'll cross check with a parts diagram that you linked to.

    Since I can't get the unit unplugged, I'll have to switch off a breaker. Discharging the cap shouldn't be a big problem if I get a screw-driver to it.

First of all, what are the symptoms? Please reply back and I'll be happy to share my thoughts.

Many parts can be accessed without removing the oven from the wall by just removing the control panel.

You need to be sure the cord is unplugged, then you remove the vent grille that runs across the top.

Then you'll see a screw holding the control panel in place. Once that screw is out, you can lift out and out carefully to separate the control panel form the chassis.

If you pull any wires off the control panel, mark and/or photograph them first to be sure you get them ALL back in the right place.

There may also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Need to replace JMC7000 Microwave


Yours will likely have a bad high voltage diode, transformer or magnetron, all of which are covered under the extended parts warranty for five years from the date of purchase!

All you have to pay is labor, unless it's less than the two-year full warranty, then there's no charge.

That's a really great warranty!

It's on the back page of the owner's manual.

If you opt for replacement, Jenn-Air Customer Care can tell you which model would be a "drop-in" replacement.

Capacitor and diode


Unless you know they\'re bad, I would test them first depending on the symptoms, since they may not be the culprit(s).

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.

How do I fix a Jenn-Air JMC7000 that does not heat up items?


The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

No power on Jenn-Air JMC 7000 ADB Microwave


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.
