Refrigerator not cooling on side-by-side fridge

First I'd like to tell you about the problem. You might have the same.

I found out that the diffuser was the problem. It sits on the top of the wall in the fridge towards the freezer side. No cold air would come in from the freezer. A little electrical motor inside the diffuser was working (one could here some clicking inside the diffuser), but the plastic piece, that is connected to the motor, was broken at the wheel of the motor (I opened up the old unit to look for the problem). So, it could not do its job, closing and opening the little windows to/from the freezer. It broke at a point where the windows/openings where closed, and in turn no cold air was coming in from the freezer side to cool the fridge.

Replacing this thing is pretty simple. I'll be very detailed, so it might look like it's a lot, but it really isn't.

In the fridge:
make some room for you to move around: take out the stuff on the top shelf. Remove the long plastic cover from the diffuser towards the door; it's only one screw. Then remove the cover for the diffuser; again it's only one screw (you won't see this screw if you do not remove the long piece first). Unplug the electrical connectors (2) from the diffuser. Also remove the thermo-lines (2); one comes from the freezer and one from the fridge. You might have to cut some tape. If you can not remove the thermo lines at this point, then wait; I'll mention them again.

Now inside the freezer:
clear out all the stuff that is placed on the top shelf(s) to get access to the cover that sits directly at the back wall inside the freezer. It's only fastened by two clips at the back of the cover. Once removed (pull it towards yourself), remove the large airflow piece that is directed towards the ice maker; it's fastened by two (2) screws, I think they were 7mm heads. Also remove the small air flow piece that is connected to the diffuser. You should now have enough room to loosen the diffuser. Just move in the four (4) "feet" from the diffuser towards the center of the hole and then push them through to the fridge side. Take out the diffuser from the fridge side. If a thermo line is still attached, remove it. Installation is just about the reverse. It should not take more than 30 min to do this. Hope it will fix your problem. As always, take good care of anything you are doing!

Diffuser replacement

The side by side refrigerator was warm on the fridge side, but good on the freezer side. I suspected the fridge thermostat and replaced it. That wasn't it. And because of the amount of frost the warm fridge was generating in the freezer the defrost module went out. After that I replaced the broken diffuser (original problem), which was very easy. You need to take the plastic shroud off of the top back of the freezer. You then will see four prongs holding the diffuser in, which is on the fridge side back left side. Unhook the two plugs and unsnap the one thermostat lead and you are good to go. I should have replaced the diffuser right from the start. If you use a mirror you can see if the diffuser is opening and closing properly.
