The microwave is the upper unit of combination microwave & conventional oven. Disconnect power to the unit. Slide unit out of built-in cabinet to expose the top shield of the microwave. Remove 5 screws holding top cover in place. Remove cover, which exposes the belt reel and drive motor. Install the new belt by threading it on the dr ... Read more ive motor pulley, then walk the new belt on the stirrer pulley. Replace the top cover and reinstall the 5 screws. Reinstall the combination unit in the wall cabinet. Reconnect electrical power. Task Complete. The belt just seem to die of old age about every seven year. Without the wave disperser operating, the microwave oven does not give even heating.

Just pulled the old support out with pliers and installed the new one which snaps in. Not sure why the support melted as it has been the same one twice now. Keep extra support clips on hand, but no need as Parts Select had the new ones here next day.

We have a Jenn-Air microwave and oven combination that is installed as a "stack" in a cabinet. The light bulb had burned out, and I read some of the posts on the partselect.com site about how others performed this replacement; ours was a bit different.
To replace the microwave light bulb, we had to remove the entire microwave and ... Read more oven stack from the cabinet. There were four anchor screws on the sides (two on each side) of the microwave that were driven in perpendicular to the face of the microwave. There were four more screws that were on the sides of the oven that could be accessed once the oven door was open.
With those anchor screws removed, we had to carefully pull the entire microwave / oven stack from the cabinet to reach the top cover of the microwave. We used an old wooden crate to hold the front of the oven and left the back of the oven resting in the cabinet enclosure. This gave enough room to access the screws on the top cover of the microwave, without having to lift the entire stack down to the floor.
At this point, I could unplug the microwave power cord, which was plugged in to a socket built into the top of the conventional oven part of the stack.
The top cover of the microwave was attached with regular Phillips head screws, so those were easy to remove. Several other instructions indicated I would need a torx or star drive screwdriver, but I did not.
Once the screws were removed from the top cover of the microwave, the cover can slide rearward to be removed. However, there are two metal strips that run vertically along the sides of the microwave and at the top of the microwave, these bends over at a right angle over the top of the microwave. The top cover has tabs that sticks up vertically from the cover, so that the bent strips prevents the cover tabs from passing as the cover is slid backwards. The vertical strips have several screws connecting it to the body of the microwave. On one of the vertical strips, I removed the two of these screws closest to the top of the microwave. Then, I gently pushed a wood chisel, because of the bevel angle, between the vertical metal strip and the microwave body. This moved the bent-over portion of the vertical strip far enough away from the microwave that the tab on the top cover cleared the strip, and I could then remove the top cover.
With the top cover removed, I could see the old light bulb. It is attached with a push-in electrical connection that was easily pulled off. One Phillips head screwdriver held the old bulb in place towards the rear of the microwave. Towards the front of the microwave, a small plastic post holds the front of the bulb. I removed the screw and pulled out the old bulb.
The new bulb fits easily into the same plastic post and screw connection. However, the new bulbs connector prongs are bent at a 90 degree angle to the original bulb. Instead of sticking straight out from the microwave, which was how the old bulb was configured, the new bulb prongs pointed to the right side of the microwave (as viewed from the front). Fortunately, the wiring harness in the microwave that connects to the light bulb had a zip tie that was loose enough to get enough slack for the push-in connector to reach the new bulb's prongs.
After the bulb was in, I reversed the steps described above, making sure to leave the chisel in place until the top cover had been secured back in place. Once the chisel was removed from the vertical metal strip, the bent portion again would prevent easy removal of the top cover. I made sure to plug the microwave power cord back into the outlet on the conventional oven, then we slid the entire unit back into the cabinet enclosure, and I put the anchor screws back to hold the stack into the cabinet.
Three of us worked on this - mostly to help pull the stack out of the cabinet and to help steady it while the front was resting on the wood crate. This is not a single-person job. It was not terribly difficult, but the number of steps is very tedious. I found a helpful YouTube video "How to uninstall/install a Jenn-Air JMC8127DD/JMC8130DD Microwave Oven" posted by Ali The Handy Man. Being able to see that the microwave and oven stack was connected by a "bridge" (as Ali calls it) was a major help in tackling this.
After this, we suspect that Jenn-Air must have not wanted any repairs to their appliances. As I said above, this repair to replace a light bulb seemed unnecessarily tedious.

remove outer cover of microwave, (special recessed star bit required) change bulb, unplug and remove 1 phillips screw.

I didn't. Don't know how to get to light bulb to change it for this specific model

removed seven screws to take door apart and replace button. Glad that you still had the part for a 25-year-old unit.

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.

Before ordering any parts I remembered seeing a fan above the nylon roof of the microwave. I had seen a belt that drove it on a prior repair 3 years ago.

I then removed 1 screw holding the electrical panel so I could tilt it open. Since power was still plugged in I didn't put my hand in. I used a flashlight and the broken bel ... Read more t.

I could also see the moter that turned the belt and tested it by starting and stopping the microwave and could see the motor pulley spin when it slowed to a stop. I then closed the control panel and screwed it in place.

That confirmed I proceded to go to the internet with the model # for the rane/microwave and looked for parts.

I had an easy job looking the part and saw that the fan as I had called it was named Stirrer because it kept stirring the microwaves over the food.

Overall I looked at 2 venders and chose Part Select because they showed the same catalog page and part numbers, and they had a better price.

I had my part/ belt in 4 working days and installed the new belt in about 15 minutes. This time unplugging the range so there was no power to be concerned with. It was a matter of picking out the old belt and putting the new belt on the motor then walking the belt over the large pulley at the Stirrer since the belt will stretch a bit.

Buttoned it up and later tested with popcorn and it left only a small amount of old maids.

Thanks, Walt

There were two hard parts for me to work through.

The first was breaking off the two screws that need a special head screwdriver to remove. None of my special special head screwdrivers worked (I have a few), so I used a hammer to force them off.

The second hardest part for me was finding the correct replacement bulb ... Read more on-line. My Amana Microwave is a combo Microwave/Convection type, and it's a strange little bulb - almost tube like.

Once I did find the right bulb on this PartSelect.com website it was a breeze. The part was delivered in just a couple of days (even during this Covid-19 pandemic). Once I had the replacement bulb in hand it barely took 5 minutes to install.

Thanks PartSelect!!

Read more bottom right back in conrol unit space. Now pull out microwave from frame about 6-8 inches. This provides access to pulleys on the motor and wave disperser. Put on belt. Reverse the above procedure to finalize the repair. This is the 3rd time I have had to replace this belt. They last about 6-7 years. Without the wave disperser , the microwave does not provide even heat.

Required that i remove the built in frame and mounting. Required tamper proof socket to remove housing. I removed the old bulb and simply replaced and reverse installed the cabinet.

Just pushed in a new clip which was very easy.
Excellent service. Only took 3 days from Calf.
