Refrigeration cycle
Refrigerators: Every 6 hours, the unit will turn off to let the evaporator coil clear up the ice. The controller
now displays the defrost symbol. When the coil temperature reaches 41°F or after 20 minutes of defrost, the
unit will turn on again. The factory setting of the temperature range is 34°F to 38°F.
Freezers: During the refrigeration cycle, the controller supplies power to the condensing unit and evaporator fan
motors. The evaporator fan will run at any time when the evaporator coil temperature is below 54°F and it will
cycle off during the defrost period. Every 6 hours, the unit will turn off and the defrost heater will work to clear up
the ice. The controller now displays the defrost symbol. When the coil temperature reaches 45°F or after 20
minutes of defrost, the unit will turn on again.
