Kenmore 106.5 side by side refrigerator, won't cool/freeze

Kenmore 106.5 side by side refrigerator, won't cool/freeze I bought a used Kenmore 106 side by side refrigerator. Got it home, cleaned it up, including the coils (it was nasty) and plugged it in. It comes on, the fans seem to be pushing cool air. The fridge initially gets cold, the freezer does not. The fridge doesn’t stay cold. I can put my hand over the vents and feel cool air in both sections. What can it be?
