COMPLAINT CAUSE 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.
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 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.
