Found the fan set to on with the cycle set to off. This caused the blower to run continuously. I switched the fan to auto and the fan shut off. Cycled the system a couple of times and it shut off normally. I checked the refrigerant pressures and determined the system has a liquid line restriction due to it having low suction pressure, slightly low liquid pressure, high superheat, and high sub cooling. I priced to pump the system down and replace the liquid line drier, purge the line set with nitrogen, check the piston, pressure test, and vacuum the refrigerant lines.
