ENGLISH COMPLAINT CAUSE s Voltage s Overload Compressor cycles on overload. s Fan motor s Condenser air flow restriction s Condenser fins (damaged) s Capacitor s Wiring s Refrigerating system s Air filter Insufficient sExhaust damper door cooling or heating sUnit undersized sCross flow fan Excessive noise. sCopper tubing Maintenance and Service 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 or 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. • Carefully rearrange tubing not to contact, compressor, shroud, and barrier.
