COMPLAINT CAUSE REMEDY
Check voltage. See the limits on the preceeding
page. If not within limits, call an electrician.
Check the wire connections, if loose, repair or
replace the terminal. If wires are off, refer to wiring
diagram for identification, and replace. Check wire
locations. If not per wiring diagram, correct.
Check the TEMP control. If not at the lowest number,
set TEMP control to this setting and restart the unit.
Check continuity of the thermistor.
Replace thermistor if circuit is open.
Check the capacitor.
Replace if not within ±10% of manufacturers
rating. Replace if shorted, open, or damaged.
Check the compressor for open circuit or ground.
If open or grounded, replace the compressor.
Check the compressor overload, if externally
mounted. Replace if open. (If the compressor
temperature is high, remove the overload, cool it,
and retest.)
Check the voltage.
See the limits on the preceding page. If voltage is
not within these 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 overload. 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 carefully and rearrange tubing
not to contact cabinet, compressor, shroud, and
barrier.
