Actually the evaporator pressure should be between 69 PSI and 78 PSI which corresponds to a temp of 40°F to 46°F. If the low side pressure in the evaporator falls into the 5* PSI range then the evaporator temp will fall below the freezing point of water and the evaporator will freeze. This can be caused both either not getting enough air across the evaporator due to a clogged filter or coil or a refrigerant leak that has allowed the pressure of the refrigerant boiling point to fall below the freezing point of water. In both cases this could allow still liquid refrigerant to return to the compressor and damage it due to the fact that liquid can not be compressed so it breaks mechanical parts inside of the compressor itself.

Not that I know shit about how a A/C works.
