Make sure to have your model number correct. First tray I purchased I didn't use the model number and just picked what I thought would work (KitchenAid), but didn't. Second attempt I put in the model number and received the correct one. Take out of the box and into the oven, that easy.

1. Removed cabinet screws (10-15?). 2. Removed cabinet. 3. Removed top interlock switch which actually was not defective. The press clip connection appeared as if it had been arcing for quite some time and the corrosion created resistance sufficient to prevent the current from getting through the switch. 4. Replaced switch anyway but broke plastic retaining clip despite every effort not to do so. Reset broken clip with super glue. 5. Reassembled cabinet and appliance is in good working condition.

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 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.

Initially we started looking to buy a replacement microwave to replace our 13+ year old built-in microwave. It was a real pain finding a replacement to fit the exact dimensions. So I thought I'd try to find an old KitchenAid microwave. However, I was pleasantly surprised when this site came up on my search. Their website allows me to input the problems and then it showed two possible parts that needed to be replaced. I emailed tech support and asked them which part I needed. They responded very quickly and said I needed to replace the magnetron. I watched a couple YouTube videos and then pulled my microwave apart. It was incredibly easy to pull the outer cover off. The magnetron had 5 screws that needed to be removed and one electrical plug. Took me maybe 10 min to complete the entire repair. It was one of the easiest repairs I've done and so thankful for this site They saved me a ton of money from not buying a new microwave and we now have our microwave working again. In hindsight, I wouldn't hesitate. I'd order the Part now and get it fixed.

Opened Box and Replaced Part......No Problem!

The power on the microwave went completely out when I went to use it, but there was no power failure for the house or neighborhood. We removed the microwave from above the oven. Took out the screws on the sides and back of the microwave and slid the top back. The line fuse was located on top unobstructed, NOT behind the button panel like some microwave models. As the appliance is over 20 years old the line fuse was quite old. It was really hard to pry it out of its holder and actually broke. I used a vacuum to suck up the dust and glass and it was easier to get out the ends once the middle broke. Popped the new line fuse in, slid the top back on, put in the screws and put the microwave back in its compartment above the stove. Good as new!! We were about to spend money on a new microwave, but thankfully I came across this site. So happy I did!!

This repair was really easy. The part that took the most time was taking it down from it's compartment above the oven and putting it back up there once repaired.

1. Order correct light bulb for unit and have it with you before removing old lightbulb.
My Microwave is built into cabinet.
2. Disconnect power (Either turn breaker off or unplug unit from wall)
3. Remove face cover on cabinet. (4 Phillips head screws)
I was able to reach in the opening in the cabinet and unplug from the wall.
4. Remove Phillip head screws holding microwave in cabinet.
5. Remove microwave from cabinet.
6. Remove Phillip head screws and torx screws holding outside cover on the back of unit and the side (1 on right side) and then remove cover.
Light bulb is on the top front right side.
7. Remove 1 philip head screw holding light bulb and unplug quick connector wires.
8. Plug quick connector into new light bulb same way it came out and place new light bulb in place and put the 1 philips head screw holding it back in place.
9. Put cover back on and all the screws. Temporary plug the unit in to test light bulb works before securing it back into cabinet.
10. Reverse order 5,4,Plug unit in wall before putting the face back on.
Done.

ordered a new tray

Pulled unit out, pried the bottom plate off the unit. Mine was not screwed in, but designed to be pried off, and then replaced. That was a surprise, but not very difficult. Unscrewed the motor, unplugged the electric connection, replaced it with new part . Replaced the bottom plate and tested the machine.

Took microwave out of builtin cabinet with 4 screws.
Put microwave on center island and removed cover.
Tested interlock switch with volt meter and it appeared ok so I put my kit back in box and sent back.
Took out magnetron unit and replace with new part.
Put cover back on and test.
All is working and installed back in cabinet. Two weeks later all still working great.

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 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!!

Unplug microwave! It's NOT necessary to remove microwave from above stove. Removed two Philips head screws on top front of unit to remove front grille. Removed one screw to remove control panel, letting it hang down. Found inline fuse in cabinet where line cord wires come in. Pulled out blown fuse with thumb and forefinger. Snapped in new fuse, replaced control panel and grille with the three screws. Plugged in the microwave. -Worked great! Good opportunity while grille was off to clean it and replace the charcoal filter inside the cabinet.

Did an online search for repairs and found PartSelect. Simple to order the part and had it installed myself less than a week later. Thank you!!
