cut power off and placed sturdy table same height as bottom of oven in front of oven. removed trim screws. pulled oven out onto table. removed top cover and panel on left side . tested transformer to be sure it was bad. then replaced transforner

This was more difficult than anticipated - probably because I'd never done it before. Once I got the door off (I didn't have the proper pins and used nails but didn't realize they had to be headless) I found all the screws, which were relatively easy to take out. I was surprised that the thermal door glass was obscured by two other panes of glass. It took more disassembly than anticipated and a few false starts when reassembling, but all in all it got done. I was happy that a job that would have cost probably $300 or more ended up getting done for $40 plus my labor - which isn't worth much these days. I'd certaily do it again.

Ordered a new one, put it in place in less than one minute.

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

Removed and replaced boiler element

Part arrived in timely manner and placed it in microwave oven.

Set the new one inside the microwave

Read all the way through this once before doing it. It really helps in keeping pieces and parts separated. First I had to take off the oven door. Please do this as it will make your life so much easier! The owners instructions does a lousy job explaining how to do this. You need to insert a small Allen wrench into the holes behind the door hinge pin. Just stick them in there and leave them. If you don't have Allen wrenches you can use small nails or the like, but you have to put something into the holes. Close the door slowly, yes it will feel like you are going to break the hinges or the wrenches. When you get the door almost completely closed you should wiggle the door a bit by the handle and pull up. The door will come off. Once you get the door off you can get to work. Leave these wrenches in the hinge holes. You will need a flat surface big enough to lay the door down to work on it. Lay it down with the handle towards the surface and the broken glass facing you. Remove the 4 screws on the broken glass side, the 2 screws holding the brackets on the bottom and the 2 screws on the top of the door. You will need to wiggle the inside cover off because there are 2 little clips at the top you need to get it off of the outer glass door. You should have 2 separate pieces, the outer glass of the door and the inner tempered glass and sheet metal portion of the door. Set the outer glass door aside, somewhere safe, as you really don't want to have to reorder that part too! From there you can lay the door down with the broken inner door glass towards the work surface. Remove the screws and good pieces of glass and lay them down in the order you take them out. This helps putting them back together later. Keep the pieces together in sets so you know which set goes to each section. There should be 3 pieces of glass total in the assembly. You remove the screws and the 2 good pieces of glass. The inside door glass is accessible under a large piece of sheet metal held in place by little flanges cut into it. You can remove this sheet metal panel piece by wiggling it out away from under the hinges and away from the hinge end. There is a piece of insulation under there as well. Make sure you reseat it correctly when you put it all back together. If you don't it will stick out, and make things hard to line up. Pull the broken glass out, Put the new glass in and replace the sheet metal panel. At this point I would suggest putting the four screws you took out at the very beginning from the inside of the door back in. They keep the 2 hinge assemblies in place and they will be harder to line up if you don't. You need to work from the bottom side up but it's pretty easy to get the 4 screws back in. Don't be afraid to wiggle the pieces around so you can line up the holes. They need to line up so that the hinges line up back to the oven. Reverse how you took the other glass pieces out and put the door back together. Put the front glass piece back on and secure it in place with the bottom door brackets and screws and the top 2 screws. Lift the door unit back up by the handle and place it in the slots for the hinges exactly the way you removed it. You will feel it sort of catch when you pull the door open slowly. Remove the Allen wrenches and you are done.

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

Followed a video. Followed instructions

Cut the power. Undid the screws to the element. Popped off the old element replaced with new,put screws back in turned power back on and Shazam it was up and going

Remove rear panel - remove sensor from inside - unplug from rear - reverse to install - did not fix problem

Removed old racks, installed new racks. Recycled old racks.

Verify power is off to the oven, turned main power supply off for the oven at the breaker panel, located the securing screws for the defective element, used a Phillips screw driver to remove the screws, pulled the element slightly out unit wires are exposed, verify 0 volts at the element wiring terminals, used pliers to remove the wires to complete the uninstalling process, reinstall the element in the reverse order, restored power at the breaker panel

It was a matter of swapping out the old door with new door. In all, it was a snap . Around 10 screws to take it apart and a few brackets to hold it all together.
