Refrigerator/freezer side by side not cooling

My Kenmore Cold Spot side by side refrigerator/freezer is no longer cooling /freezing. The lights and cooling fan are working. I took off the back and I could hear a slight clicking noise, like the compressor was cycling. The compressor tank was hot. Any ideas what is wrong?

If the compressor was too hot to touch, it may be clicking off on overheat. If it’s hot, but doesn’t burn you when you momentarily contact it, start checking inside the freezer section. Do you see a frost build-up? Perhaps even enough to bulge against the panel inside it, at the back? Remove the rear panel inside the freezer and tell us what you observe; especially the physical appearance of the evaporator coil (frosted? smothered in snowy frost? Localized block of frost or ice? etc.).

i have the same issue and I have taken off the back panels inside the freezer and found frost/ice buildup on the coil. Also the fan in the freezer, above the coils, is not running.
