KEMS378GSS3 KitchenAid Microwave Oven Combo - Instructions

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 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

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"

Found a way to remove screw. Proceeded to insert new spring and tried to assemble but had same problem to put screw back in. No normal tool was able to fit in and could not remove vent. Finally able to engage screw and finished reassembly.

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

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:

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.

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 took the new tray out of the box and placed it in the microwave oven.. No tools needed.

I looked up the problem and determined I needed to replace the limit switch which is inside the back panel. As a 78 year old woman who isn't afraid to tackle these problems I found this easier than most. Just be sure to disconnect the electrical connection if you don't have long enough length to pull oven from the wall cabinet. I won't put any sheet pans in the oven next time I self clean it.

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

1) Removed the trim pieces (2 screws). 2) removed the 2 screws holding the oven in the wall. 3) Slid the oven out of the wall cabinet 4) removed the back panel of the oven ( 10 screws. 5.) removed the old thermostat (2 nuts) 6.). Installed the new thermostat and reversed steps 4-1

Several professional appliance repair people told me I had to get a new oven (double, no less!) because "they don't make that hinge anymore." That would have been a $4-5K investment to replace two ovens that both work fine. I'm not generally a DIY person, but was inspired by a FB page I follow called "Handy Women." I got the model number out of my oven, googled "replacement hinge for ____," and found it on this site right away. $120 and about 1 week later I had my hinges. I found this video in the comments on this website that shows (without narration) exactly how to change the hinges.

The only mistake I made that cost me some time had to do with the little pins you have to put into the hinge to remove and replace the oven door. They were missing from the old hinges, and it didn't occur to me to use the ones that were in the new hinges (hadn't unboxed when I started.) I used threaded bolts that were the right diameter and length. They slid right in, but then when I went to take them out, it was an ordeal with WD-40 and an Allen wrench. Then it still didn't occur to me to look at the new ones, so I went to the hardware store and bought two more things the right size without threads. Of course when I took the new hinges out of the boxes they already had the little pins in them. Annoying and time consuming rookie mistake, but my oven door now closes just fine, and I'm getting a ridiculous amount of satisfaction from my little repair job!

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.
