COMPLAINT CAUSE
REMEDY
Check the voltage. See the limits on the preced-
ing 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
(do not damage fins). 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.
Remove the cabinet and carefully rearrange tubing
not to contact cabinet, compressor, shroud, and
barrier.
