KEMC378KSS01 KitchenAid Microwave Oven Combo - Instructions

Unscrewed the old thermostat took off the conectors then replaced with new one, and screwed it back on.

I followed these instructions put in by a fellow customer. These were very helpful. Just make sure the glass is finger print free before you put it all back together. My time was 30 minutes end to end. =========================== The first thing I did was to remove the oven door by releasing the two latches on the hinges (by hand). I then raised the door toward the vertical position and lifted up. The hinges slide out of the oven housing. I laid the door, inside face up on my island counter top. This ensures that none of the parts will fall when disassembling the door. Next I unscrewed the screws 4 top and bottom and four on the inside face. This releases the frame from the front housing. Lift the frame off the door, exposing the glass pieces. Lift off the broken inside glass and place the new piece in the glass retaining housing. Replace the outside frame and replace all screws. Take door back over to oven and slide hinge bottoms back into slots on oven. Rotate to horizontal position and flip latches back to locked position. Total time was about 10 minutes mainly because I was curious how the door was constructed and I poked around while it was disassembled

1. Unplug the power cord from the wall socket. 2. Remove the 10 screws holding the bottom cabinet cover in place. The bottom cabinet cover will swing down allowing acces to the inside ofe the microwave. 3. Remove the connector from the turntable motor. 4. Use a T15 Torx driver to remove the 2 Torx screws holding the motor in place. 5. Remove the motor. 6. Reverse the process using the new motor.

re thermostat/fuse breakage after cleaning: I replaced the part a 2nd time within a year, both times after a cleaning cycle and after 10 years of no similar problem . This time, when putting the oven back, I cleaned all around the door frame and noticed the exhaust grill was heavily filled with dust strands. It's possible this reduced the exhaust enough to overheat the oven during long high temp cleaning and blow the thermo fuse. Just a thought.

Turned the circuit breaker off, removed trim and the oven screws, pulled oven out, and placed on a stand in front. Electrical cord was just long enough without disconnecting. Removed the back panel, installed the old thermostat with the new one the same way. Used the same phillips screwdriver for the operation. Installed the oven using reverse order. Turn circuit breaker on, back in business. Prior comments definitely helped me a lot. Thanks.

To remove the oven door, you have to slide 2 small nails into the holes in side of the hinges. When you then close the oven door, the nails force the hinges out of the oven box, and the door comes off. Lay the door on a cloth face down, and remove the phillips screws around the perimeter. The door comes apart in layers, with more screws and layers of glass inside. Lay in the new glass, and reassemble. Carry the door over to the oven and push the hinges in hard at the bottom. Lay the door flat to remove the nails. Close the door. Job done.

Removed trim strip from each side of oven, removed one screw from each side hat held oven in place and slid oven out of wall. Finally found the thermostat located on the back side of the oven after removing the sheet metal on back. replaced the thermostat and reversed the procedure. Only difficult part was locating the thermostat. I thought it was on top, when in fact it was on the back. Pretty easy, really, and saved some cash in the process.

Had to screw off old terminal block & screw on new one

The only difficult part of this repair was figuring out how to get the oven door off. Most instructions advise you to flip the hinge locking clips, then lift off the door. But this oven does not have hinge locking clips. What it has is holes in the hinges, just behind the hinge pins. To get the door off, you need to open the door and insert some 3/16' pins in those holes, then close the door and lift it off. I almost got this right the first time, but I used 1/8" pins, and they didn't work, too small. It took me a long time to figure out to use bigger pins. Once the door is off, it's just a few Philips screws to work your way down to the glass. There are 4 layers of glass in this door.

By reversing the way I removed the door hinges from the frame, per the reinstall instructions. I called the 800# and they emailed me a diagram, but the hinges depicted were different than mine. When my back feels better, I'll keep trying.
