Maintenance and Service
Compressor
cycles on
overload.
Insufficient
cooling or heating
Excessive noise.
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.
