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.

Oven stopped heating and showed fault codes
After 22 years the oven stopped heating in the middle of a meal prep. The fault code was F3 oven temperature problem. I googled the codes and found PartSelect described the problem and the repair and part needed. I received the oven sensor part, then turned off the power, used a screwdriver to remove 2 screws (had to find the right size flat head screwdriver to fit the square holed screws and they were pretty baked on after 22 years of use), gently pulled the sensor and wiring through the back of the oven. I used a needle-nose plier to pull the plastic connector through the insulation, then unsnapped the connector, snapped in the new sensor connector and pushed it back through the oven wall. Pretty simple repair, took me longer to find the screw driver than the actual repair. Thank you PartSelect for making it easy and saving me a repairman visit!
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.
Remove the left/right outside trim on the double oven. To do this you will need a phillip screw driver. There is only one screw holding each side located at the bottom of the trim (on the inside between the trim and the door). Remove the trim by pulling out and down. Remove the bottom trim by removing the screws located on the outside of the trim. Remove the trim by pulling down and out. Replace the new trim by reversing the process making sure to replace bottom trim first because the outside trim goes over bottom trim to cover up the screws on the bottom trim
First remove the side trimmings by opening the oven door and taking out the two screws near the bottom. Remove the bottom trim by removing the two screws now exposed. Here's the hard part .. The outer glass is held by 4 screws 2 at the top and 2 through U brackets at the bottom. You must remove the 2 bottom ones first and then VERY carefully, whilst supporting the glass remove the 2 top ones and then gently pull from the bottom to release the glass at the top and pull away. The rest is straightforward. There are 4 glass pieces to remove, make sure you clean the finger marks off as you replace them. I would suggest 2 people to replace the final outer glass 'to be safe"
The oven in the demo video did not have an interior set of screws holding in the exterior glass
Watched the repair video and started the project. Ran into a problem when trying to remove the interior panel off the door to reach the broken interior glass. On this model Kitchen Aid there is another section that is screwed in holding the exterior glass pieces in place. It prevents the interior panel from coming off the front of the oven door. So we had to flip over the door and unscrew the glass retaining bars to get the interior panel off and reach the glass. This allows the entire door to come apart in pieces so you have to carefully line up everything to re-assemble the door. Part of the issue with this is some of the retaining screws are not very long so you have to press the pieces back together to make sure the screw will catch in the original hole. We had to do this twice to ensure the interior door glass was laying flush on its mounts. A bit fiddly for sure, and if I was working alone it may not have been successful. But at least we know how the door is put together!
My oven (late 90's/early 2000's model) didn't have the flip-down hinge locks shown in the video. It seems Whirlpool/Kitchenaid changed the hinges even though they didn't change the model number of the oven. With my style hinges, you have to put Allen wrenches or bent nails in the holes just behind the hinge pins. Then close the door almost all the way and lift it out to separate the hinges. Spring force holds the nails in tightly until you replace the door. This video was very helpful: https://www.youtube.com/watch?v=p7oRZdIN6m0
Also, my door had 3 different kinds of sheet metal screws. Two of them have similar heads but different threads. Keep track of which is which for when you put everything back together.
Both glass windows in oven door broke due to water falling on 500oF hot glass
we live in Venzuela the ordered windows come to us via a forwarder in the US, one glass (the outer glass) still has to arrive. Very pleased with the service of PartSelect, one glass was in stock, the inner glass had to be ordered with the manufacturer. This glass is on its way and will arrive here in Venezuela by the end of May. As I have to travel to Europe next week, I will install both glasses upon my return somewhere in August next. I will sure inform you about the repair which will be done by myself. regards, Titus
Thanks to video provided by PartSelect the repair was fast and easy. My second experience with an appliance repair with parts and video from PartSelect. I am a happy customer.
