Samsung Fridge Not Cooling? Freezer Works Fine..

I've run into this with a few different sticks and bricks fridges. In each case, the problem is that cold air isn't flowing from the freezer into the fridge.

You can take stuff apart and find the blockage, or you can just unplug the fridge, prop the doors open, and let it sit and warm up for 48 hours. 24 is often not enough.

Or you can do like I did when I was impatient, and put a hair dryer or space heater in there, and melt the interior of your fridge. That works too, although it's less pretty.
