KTHS20KBAL00 KitchenAid Refrigerator - Instructions

I simply slid off the broken supports, and slid the new ones on.

I removed one bolt and took out the old roller after first blocking up the fridge. Then I was puzzled for a moment because the hole in the new assembly was not tapped. But then I saw that the old bolt was a self tapping bolt. I used it to tap the hole then removed it and installed the new assembly. No sweat job.

I removed 7 screws hold the heavy cardboard cover on the rear of the fridge. The dificult part was taking the screws that hold the 3 fan motor braces on the fan out. After that it was a matter of making the wire conections and putting it back in. I did not have enough room to laydown to do the work, If i had it would have been a lot easier to see the screws that had to be removed. All in all an easy job, and the part was a perfect fit.

Unplug fridge, unpluged fan motor from plug socket, removed bracket screws, removed fan retainer clip from shaft. removed screws holding fan to bracket

I just replaced my defrost thermostat after using the place-in-ice-water method, and I think it may not have been necessary. My timeline: my fridge was not getting cold enough. I realized it the day before going on a trip. I vacuumed the (very dusty) coils at the bottom, and the next morning the fridge seemed colder, but I thought I should order parts just in case. I ordered a heater and a thermostat. The fridge seemed to be operating normally when I returned from my trip, but I had the parts, so I thought I'd go ahead and dismantle the freezer and test the existing parts. My intention was to return both parts if the old ones passed the tests. I opened up the back of the freezer and there was no ice on the fins. I thought, great, the existing heater works! I cut out the thermostat, placed it in ice water, and didn't get continuity. So I decided to go ahead and put in the new thermostat. Because I'm not experienced with using a multimeter, I thought I'd test the new thermostat to see how the test should work. To my surprise, the new thermostat also failed the test! Stumped, I thought I might as well install the new thermostat, since I had opened the package and couldn't return it.
Further internet research suggests the place-in-ice-water method of testing is not adequate. One YouTube video by Parts Dr says to place the part in a working freezer. I froze my old thermostat and tested it; still no continuity. This thermostat may not be typical, though. The video discussed the temperature ratings on thermostats. The temperature rating on both (old and new) thermostats is L8.9-16.7C. That converts to 48-63 degrees fahrenheit, which obviously are not freezing temperatures. I'm not convinced I needed a new thermostat, but I trusted the videos I consulted earlier.
I cleaned the fridge thoroughly, so at least now I have a nice clean fridge to show for my efforts.

I attached the hinge and secured it with screws and socket wrench.

Removed door and replaced bushing bracket was ok.

Simply took broken pieces of old stud out and replaced with the new ones. Used pliers to adjust them. Replace a freezer stud and a fridge stud.

removed old and instaslled new. biggest problem was getting to one of the screws.

replaced ice maker with recommended add on kit. easy to replace exact replacement. used this company for washing machine part. parts correct both times.

I removed the nuts that held the motor mount, then removed fan blade, cut the wires, and slid the motor pass the mounts and the coil shroud, Installed motor in reverse order. worked out ok.

removed lower back cover. diconnected fan ass'y electrical connection, removed fan housing (3 screws). removed fan motor from housing. cut old connector from fan and installed on new fan with wire nuts included. re-installed new fan to housing and re-installed housing to frame.

Partition between Freezer and Fridge was running very hot. (Warm is normal). Oiling fan did not work. The only problems encountered in the replacement were getting fan out and in through coolant lines, cut plug off to accomodate generic fan wiring, getting the screws back in without cooking your hand on a hot compressor. Unit works great!

Ordered new fan motor on line took out old motor and replaced with new one

The instruction sheet supplied with the new motor described the steps to take very good. Replaced the rubber grommets for the three motor mounts also. A flashlight or light source was needed or was very helpful.
