COMPLAINT Compressor cycles on overload. CAUSE Voltage Overload Fan motor Condenser air flow restriction Insufficient cooling or heating Excessive noise. Condenser fins (damaged) Capacitor Wiring Refrigerating system Air filter Exhaust damper door Unit undersized Blower or fan Copper tubing REMEDY Check the voltage. See the limits on the preceding page. If not within limits, call an electrician. Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) 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 reassembling. If 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 capacitor. Check the terminals. If loose, repair or replace. Check the system for a restriction. If restricted, clean of replace. Close if open. 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 air guide, rearrange the air handling parts. Remove the cabinet and carefully rearrange tubing not to contact cabinet, compressor, shroud, and barrier. -25-
