Not cooling comes from one of four places
A refrigerator that will not hold its setting has lost one of four things: air across the condenser, air across the evaporator, a clear evaporator, or a working sealed system. The diagnosis goes in that order, cheapest first, and the sealed system is read under gauges once the first three check out. You get the cause and one written figure before any repair starts.
