I googled the issue and read several articles. Most started with cleaning the coils (which mine are on the bottom) (19yr old Kenmore 363.9557812). I had not really ever cleaned them well, vacuuming did little. I had to remove the cardboard cover off the back of the frig, and blew them clean (front to back). Once that was done, I started cleaning from the back and noticed the fan wasn't turning week (condensor fan). Blew it out too, have it a good soon with a pencil, it puffed out a bunch of dust and started to work. Within about 30 mins the frig, was performing normally again. But the fan stopped over night. I went to Walmart and bought a small $15 personal fan to put behind the fridge on high (faced at compressor and coils) and that "fixed" the issue (cardboard still off). This worked until I had a chance to buy the part I needed. I found Appliancepartspros by searching for a video on how to resolve the part, they also ended up having the best price, even if I used a coupon code on the other sites. Shipping was cheap and it was here in 3 days. Powered off frig... My old fan motor has a large torx screws holding it in place. The new one came with flat heads. I had to disassemble before removing ft from the back of the frig, due to space. I used the old screws and the old nut to reattach the fan blade (motor does not come with blades,but easy to swap). Power cord did not click into place on fan motor, but does fit firmly. I out the fan blades on backwards the first time, but its working great. It is louder than the original, but that could be because it wasn't working right for some time.
