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.

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.

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.

Well, the instructions on the computer site were very easy to understand, however, the difficulty lay in the fact that we were 2 78 yr old people and getting to the inside the oven, lifting up the element so that we could see where it should be connected and get it connected was a task. We had to get down on our knees and then get back up. That was a chore within itself. But, the instructions were easy and clear.
Bottom line if us old people can do it, anyone can.

unscrew cover
remove old bulb
screw in new bulb
replace cover

I was able to remove the old element and planned it with what little time off that I could. This would have been maybe 20-30 minute repair at the most. HOWEVER! I was extremely irritated screws were not included? When I called to ask if they were missing they said they didn’t come with the element. Cost me a very annoying trip to the hardware store. Not sure if I missed it on the site that they don’t provide screws - would have been nice to know that before I started. Still scratching my head as to why screws wouldn’t be included? My old ones were as beat up as the element I replaced. I was so irritated I was looking for a spot to leave feedback. Product is fine. Shipping was fine. Sending these products out as they do? Zero stars on that.

Just put it in

Fool proof.

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

I put the tray in the microwave???? Pretty easy.

I turn off the power in the breaker box and then unscrew the part and replace it with the new one

removed perimeter screws from the bottom side and the lower cover is hinged at the wall side. Motor is visible and easily removed with two screws. Take of the old one, install the new one, and reverse the procedure to put the bottom cover back in place. Will nee helper to hold one side of the bottom until couple of screws can be put in on the other side.

Small, older female with limited hand strength here. Turned off the power to the stove. Removed the baking element from the oven wall with a screwdriver, snapped out the old one and snapped in the new one. 5 min tops. The broiler was a bit more labor intensive as the rusted and/or stripped screws did not want to come out. Used some liquid wrench, gripping grit, and a power drill to remove, but once the screws were out, it was another easy snap off/snap back in process. Had some screws on hand to replace the stripped ones. Broiled a steak that night with the new red hot broiler. So happy. This repair just saved me approximately $1800 to replace a 28 yr old drop-range. Very happy with this purchase.

Very easy. Take the two top screws out and the two bottom holders off. The bottom holders hold the glass up in place. Grab the handle and pull glass out. To install put handles screws back on the glass and slide in place. Once in place install the bottom holders pieces back on. *** I would buy screws because after years of use the head rust out and sometimes they are hard to get off... all in all very easy to install
