Oven combo, oven works but the micro has no power

The fix for my problem was to remove the oven/microwave combo unit, and press the reset button on the back of the microwave. Oh yeah, and to write a $75 check for a 10 minute service call.

You want to try the fix for yourself? You have to remove all of the face screws holding the unit in place. There are 4 on the microwave front and 6 in the oven, 3 down each side, inside the lip where the door is. You must remove the door to get to the bottom ones. You don't have to remove the screws holding the plastic insert in place between the micro & oven, but you might want to remove the metal lip on the bottom of the oven to help prevent scratches to the cabinet. After that's done, get a helper and pull the unit most of the way out, then rotate a little to the left. That will expose the reset button on the back, right side of the microwave.

We (it will take two of you unless you are Godzilla AND you can tie the oven door shut) were able to slide the whole unit out just enouth to be able to tip it forward just enough to reach the cord from the microware and the switch next to the outlet on the top of the oven. In our case there are extra 110v outlets in the cabinet cavity so we plugged the microwave into on of the new 110v outlets and hope to not have this problem again. My thanks to all who contribute here because without your insight I would have called the repair man and spent $$$ I don't have. Thank you.

Whatever

MINE DID THE SAME THING I JUST GOT DONE PULLING IT OUT AND RESETTING IT WORKS FOR NOW. WHAT A **** POOR DESIGN, THINK I WILL SEND A E MAIL TO JENNAIR AND TELL THEM HOW MUCH OF A JOKE I THINK THERE PRODUCT IS. Hell i paid 59.00 for a microwave that lasted 17 years.NOT HAPPY, thanks to all

When you have the unit out of the wall to reset the breaker, take the microwave power cord and slightly bend the flat prongs out so that it makes better contact in the outlet. That should solve the problem once and for all. Mine started tripping the breaker and got so bad that it would not operate for more than a minute at a time.

We finally got this fixed (been more than 6 weeks and the problem has not surfaced). the fix was replacing the power supply plug. it was not a snug fit with the female in the back of the oven. alternate fix could have been plugging the power supply directly into a wall socket.

Confirming what Jimk12345 and whirlpoolbad have posted. On the microwave / oven combo, there is a circuit breaker on top of the oven in the back next to a 110v outlet that the microwave plugs into. Our tripped during oven cleaning when the microwave was used to heat a dish. The only way to access the reset (other than going through the wall) is to slide the oven and microwave out far enough that you can reach in behind the microwave and reset the 20 amp breaker. Of course onle do this after everything has cooled down!
Not sure what idiot designed this, but it certainly was NOT an engineer.

Just confirming what JimK12345 experienced is exactly what fixed my problem. Why Jenn-Air/Whirlpool will not acknowledge this design flaw nor disclose this simple solution is beyond me.
I would suggest you contact Jenn-Air to complain about this issue and seek reimbursement from them if necessary.

My solution is similar to JimK12345 but my problem was described as an "on/off" switch on top of the lower oven below the microwave. My first check was for $118.00. It went to the repair service guy covered by the warranty (the unit had only been in for 5 months). Repair guy determined that the problem was electrical as everything checked out okay and advised me to call an electrician. As electrical problems are not covered by the warranty, I had to write the guy a $118.00 check for his time. (The warranty repair guy is not authorized by by Maytag/JennAir/Whirlpool to unscrew the unit, remove the door and look behind the stove).

I then called the contractor who installed the unit during our recent remodel. ( I called repair guy first because, after all, the unit was under warranty. I knew the electricity was fine because the oven was working, so common sense told me it must be a problem with the microwave). It turns out there is a switch on the top of the lower oven below the microwave that, for some reason, must allow a person to turn the microwave portion off, leaving only the lower oven operational. This switch had gone from "on" to "off" - evidentally as a result of vibration during the cleaning process when the microwave was started. I wrote another check for $100.00 to the guy who installed the oven. $218.00 later - and 10 days later - I was back in business. I called the repair guy to let him know what the problem had been, and he didn't know why the switch was there - but said the impractical engineering on the JennAir caused some strange problems at times...

It's important to know that, if this is your problem you will be paying two repair people if you are under warranty. I am curious to know if this was the solution for many of you with this problem. Hope it helps.
