First, check whether the compressor and fan are running. If neither runs, check the 12V/120V supply and the power supply board. If the compressor runs but it won't cool, the sealed system has likely lost its charge, which is a big repair on a DE0051. The thermostat is also a common failure, and the 605505420 fits the DE0051.
