may disable the compressor clutch.  If the ambient temperature is less 
than 45ºF the freeze switch may disable the compressor clutch.  In order 
to troubleshoot an inoperative compressor clutch at temperatures between 
45ºF and 65ºF, use a short wire as a jumper between Pin 7 and Pin 8 of

present, check the KAC-CCB-16 wire for continuity.  Replace/repair 
as necessary. 
9.  Check for continuity of the pressure switch.  If there is no continuity at 
the pressure switch, check the refrigerant pressure.  If the discharge 
pressure is between 35 and 340 PSIG, discharge the air-conditioning 
system and replace the JBS2020-5 Pressure...
