COMPLAINT Compressor cycles on overload CAUSE Fan motor Condenser air flow restriction Insufficient cooling. Excessive noise. Condenser fins (damaged) Capacitor Wiring Refrigeration system Air filter Unit undersized Blower or fan Copper tubing REMEDY If not running, determine the cause. Replace if required. Remove the cabinet, inspect the interior surface of the condenser. If restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before re-assembling. If the condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to cycle. Straighten the fins or replace the coil. Test the capacitor. Check the terminals. If loose, repair or replace. Check the system for a restriction. If restricted, clean or replace. Determine if the unit is properly sized for the area to be cooled. Check the set screw, or clamp. If loose or missing, correct. If the blower or fan is hitting scroll or barrier, rearrange the air handling parts. Remove the cabinet and carefully rearrange the tubing not to contact the cabinet, compressor, shroud, and barrier. -25-
