Refrigerator too warm, freezer fine

I replaced the Diffuser and the Thermistor (the one in the refrigerator) at the same time. I was not sure what the problem was ahead of time except for the fact that no air was coming in from the freezer section; this is where the air diffuser is. I probably only needed to replace the diffuser.

I turned the circuit breaker for the refrigerator off. There was a small section of plastic covering the wires that run from the top console inside the refrigerator to the back of the refrigerator where the diffuser is. I took this off (one screw) and then the diffuser is connected in the refrigerator side with one screw. To push the diffuser from the freezer, I needed to take off a piece of plastic directing the flow of air from the freezer. I needed to move the ice maker forward a little; it moves forward easily (it sort of clips into place). Once the diffuser was visible from the freezer, I pushed it out or disconnected the four clips holding it in and it came right out. Once this is done, you simply unplug the old and plug in the new and put back in place. This took less than 15 minutes total time. Online diagrams makes ordering parts and fixing easy.

Once the new diffuser was in, I could tell I was golden because I was getting cold air. I guess this piece goes bad from time to time based on others experiences.
