S SS SSS 2 The temperature control board and P1 probe indicate when the refrigeration system is required to turn on and off The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air When the cabinet interior temperature reaches 4 F 2 2 C above the controller set point the probe signals the controller to turn the refrigeration system on The normally open controller contacts close and energize the condenser fan motor and compressor The evaporator fan runs continuously The compressor uses a PTC device to turn on the compressor motor When the cabinet interior temperature falls to the set point the probe signals the controller to turn the refrigeration system off The controller contacts reopen which de energizes the evaporator condenser fan motors and the compressor Automatic Defrost REF Series refrigerators do not require manual defrosting The unit defrosts automatically when the condensing unit is in the OFF cycle Any accumulated frost on the evaporator coil melts during the OFF cycle The condensate drains to a plastic drain pan mounted below the condensing unit The heat from the condensing unit evaporates any condensate in the drain pan Controller Operation Fig 8 In normal operation the controller displays temperatures in degrees F default or user selected degrees C F temperatures are displayed to the nearest degree C temperatures are displayed to one decimal point
