FIrst, I removed the cardboard cover on the back, exposing the compressor compartment. I noticed the fan was not moving. I touched the blade and it immediately started spinning, but not very fast. The compressor was getting hot, and I think prob. overheating. The fan stopped after a few hours and then "froze" solid the next day. I got the parts and I followed the process in the video to replace the fan. VIdeo was right on the money. but there were some difficulties. The retention clip on the wire connector was brittle and it broke off. The kit had an adapter plug, but without the retention clip it was not secure, I simply put a tie-wrap around it and held it tightly. I noticed there was some ice in the freezer so I assumed the defrost timer was bad and I got one of those too. I first noticed that there was no cold air blowing from the top-back of the frig compartment. That was a big tip-off that the coils were iced up. I took off the light housing in the frig compartment and quickly saw that the back vent opening to the freezer compartment was 100% iced-up and blocked (no cold air getting to the frig).. I took the four screws off the back panel of the freezer, but it was frozen solid at the bottom where it sticks through to the frig compartment. Not wanting to break the plastic back panel part, I wisely used a fan to defrost the the frig, and after a couple hours the back panel came right off. The cooling coils were like a solid block of ice. It took a few more hours with the fan to defrost it. I put in the new defrost timer (easy) following the video. The new fan assembly is plastic and looks different, but fit exactly. It was a bit difficult getting it in because the cooling tubing was in the way, but after a bit of a struggle, I got it in. The hint in the video to put in the back screw first was a lot of help. Strangely, when I turned the frig back on after the 6 hours of defrosting, nothing happened. The light came on in the frig but no compressor noise and no cooling. I unplugged it and I left it overnight, and then plugged it in in the morning and everything started right up and it is working perfectly now, both frig and freezer. I recommend replacing both the fan and the defrost timer, even if you are not sure.
