Loud buzzing noise and no heat.
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.

Broken Inner Glass on Oven Door by a Grandmother Who Should Know Better!
After reading all the other entries, I decided that I could do this! My first hurdle was getting the oven door off the hinges. Mine were not like any of the others described. My son-in-law looked at them and couldn't figure them out. So, I found the original installation instructions and, lo and behold, they said to flip the lever (one finger operation) in each of the rectangular holes holding the door onto the oven and then lift up until the door comes off. I did it, and it did! Boy, is it heavy! From there I just followed everyone else's instruction about undoing the screws, washing the glass panels, lining up the screw holes to get it back together, etc. One thing that took me longer was that the steel panel needs to go back the way it came out, not flipped! When I washed the glass panel it held, I put it down wrong and then "installed" it backwards. Luckily, I have a double oven and looked at the other one to see what was holding up the re-assembly! I'm glad that one of the others mentioned that the glass on the "bottom", the one that broke, isn't held in my screws or steel plates -- nothing, so I wasn't surprised when I got to it and it was "floating" on the insulation. My white insulation was like a fine fiberglass and was easy to stuff back in around the rim of the new glass. Took me a little over one hour. So, no more wet rags on hot glass (you'd think after living 72 years that I would remember this!) The glass fit perfectly and my husband would have been proud of me -- that I tackled a job that he usually handled, and that I saved over $200 for a couple of hours of labor and travel time.
Removed the door from the oven. Undid all the parts above the inner glass door. Installed the inner glass and reassembled the door. Reinstalled oven door.
Originally ordered just the spring assuming that might be it and it was the cheapest way. However after getting in I found that the latch assembly had a broken 'tit' that is intended to hold the metal latch in place as it moves. Attempted to glue w/ epoxy but as i expected there was too much pressure to hold it in place. So....ordered the assembly.
TURN OFF BREAKER.....
1) Remove the two side rails by removing screw on the inside bottom of rails. 2) It helps to remove the door to get it out of your way but not required. To do this open door fully and insert two nails or similar into holes on each hinge. Close the door until the hinge contact nails. Lift the door up and out. 3) remove the top control panel by removing screw on either side (outside of oven)and screws on the underside of panel behind upper door. 4) It help to completely remove the panel to have more room to work but not required. If you do it is a good idea to photo the cable locations so it is easy to recall where they go. For the most part they only fit one location but always a good idea. 5) remove the latch by removing all spade connectors and two screws in front. 6) place new latch and reassemble.
With just the removal of a few screws I was able to replace the glass with the side benefit of cleaning the outter glass that had gotten dirty over the years with use. This is a simple project that all can complete.
I was trying to remove the oven door so I could clean the glass. Spills had run down between the layers of glass.
This oven probably was manufactured in the '60s when the house was built. The door doesn't just pull off like the newer models. These pins fit into small holes on the oven hinges. I inserted the pins and lifted the door to a 45 degree angle, before pulling the door completely off. Now that turned out to be the easy part. I then proceeded to completely dismantle the door. It actually has 4 glass layers which had to be cleaned individually. The hardest part of all was actually remembering how to put it back together again. I put the door back on just as I had removed it, then took out the pins, and I was finally done! This was not an easy project, BUT the results look great.
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.
1. Disconnect AC power 2. Remove back with several sheet metal screws. 3. Remove wires from Limit Thermostat. 4. Check Limit Thermostat continuity -- if open then Limit Thermostat is faulty. 5. Remove Limit Thermostat with two screws. 6. Install new thermostat
Since there is multiple glass panels with several brackets, screws and insulation within the oven door I strongly suggest to take photos at each step using your smart phone. Do not attempt to remove all the components at once. Bracket positions, screw locations and glass orientation is necessary. This is the best advice I have to make this a quick and very easy job.
