Abstract: An icemaker having a means for bypassing a head pressure control valve thereof depending upon the ambient air temperature surrounding a remotely located condenser of the icemaker. The method and apparatus involve a first bypass conduit which is coupled to an outlet of the condenser upstream of the head pressure control valve and a first bypass valve disposed in the first bypass conduit. A second bypass conduit is in communication with an inlet of the condenser and also with the head pressure control valve. A second bypass valve is disposed in the second bypass conduit. A thermostat controls each of the bypass valves such that the first bypass valve is closed and the second bypass valve opened when the sensed ambient air temperature around the condenser is below a predetermined temperature, to thereby permit normal operation of the head pressure control valve.
