KEMC377KSS05 KitchenAid Microwave Oven Combo - Instructions

Disconnect the sensor harness and checked resistance on the sensor,should read around 1100 ohm I only got 25.The sensor is mounted in the oven cavity back wall below upper element,the door must be removed. Unscrew 2 Philips head screw,unhook the harness,install new sensor,reconnect harness,install screws.

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

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

Set the new one inside the microwave

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 ... Read more 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.

Used the instructions I wrote up the last time. Printed them off, and still works like a charm.

This makes third time the spring has broken - last two times it has been the right side spring. Not the best designed microwave door. But at least with PartSelect having the part, and with PartSelect keeping my original instructio ... Read more ns on the website, the repair is easy.

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

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.

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.

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, ... Read more 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.

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 al ... Read more most 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:

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.

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 proce ... Read more eded 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.

I followed the instructions that were posted for a do-it-yourself on the part. The instructions were spot on. One addition that I have to the online instructions is that I have a wall mounted microwave and had to remove the trim before starting the instructions. Additional instructions for wall mount are:

1. Remove one screw ... Read more each side from inside the door to loosen the vertical trim.

2. Remove the vertical trim on each side.

3. Remove the 2 screws holding the bottom trim and remove the trim.

4, Follow the remaining instructions

Just put it in

Fool proof.
