I found that what was keeping the old temp sensor electrical connection attached to the stove-side connection was a little tab. It wasn't obvious that that was the thing that was keeping the connection secure but there weren't any other alternatives. So pushing the tab up with the metal probe (just a narrow rigid metal wire) allowed me to pull the connection apart.

All this takes place way at the back of the oven so its difficult to fiddle with a screwdriver and the retaining screws at arms length. Putting a bit of scotch tape around the screw to keep it attached to the screwdriver kept it from falling off. My hand was a bit shaky extended like that so that was the way to go.

Bottom line, if your oven won't reach or hold the temp you dial in on the control panel it's the temperature sensor. Now if I set it for 300 deg. that's what I get.

XLarge pizza tray in a 450 degree oven - slam the door & CRACK. Replacement glass arrived on Saturday - VERY FAST DELIVERY. Placed 2 allen wrenches in both hinges - open the door half way & lift up. Place the door on a towel. Removed 6 screws, lift & seperated the inner oven covering, removed the broken glass & cleaned inside & replaced with new glass. More time was spent cleaning & coming up with a tool to fit into the hinge

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

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.

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

I bought an old house where this Double Wall oven was not working. I looked at the suppressor and one of the Red diodes was burnt. So, I removed it, took a picture of it and send it to the sales rep. She located the part exact part and sent it within 3 days. Then I installed it and the oven worked beautifully. My Appliance repair man gave me an estimate of $760.00 and I was able to repair within 30 minutes and $60.00 part. Really happy, Thank you .

I followed the instructions per a YouTube video. My older model was slightly different in parts used in the video, but the general idea was the same. Very happy with current repair / parts. The door now opens smooth as glass, and I even got a chance to clean some internal parts inside the door.

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

Quickly

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.

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.
