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.).
