(6) Evaporator Fan Runs
Ensure the evaporator fan is running, see #2 on page 22.
(7) Voltage at Motor?
Check for the proper voltage at the motor. Voltage should be ap-
proximately 115V.
(7a) Find Voltage Interruption
Determine where voltage is being interrupted and correct. See wir-
ing diagram for circuitry.
(8) Fan Blade Obstructed?
Ensure the fan blade is not obstructed.
(9) Fan Motor Defective
Replace the fan motor.
(10) Condenser Fan?
Check if the condenser fan is operating, see #4 on page 22.
(11) Voltage at Motor?
Check for the proper voltage at the motor. Voltage should be ap-
proximately 115V.
(12) Fan Blade Obstructed
Ensure the fan blade is not obstructed.
(13) Fan Motor Obstructed
Ensure the fan blade is not obstructed.
(14) Compressor Runs?
LED Snowflake must be illuminated for compressor to operate.
Using a clamp on style amp probe, determine if the compressor is
drawing current and record. If compressor is running go to #19.
(15) Power to Compressor?
Check to ensure power is at the black wires leading to the over-
load (115 V nominal). If no power, find where the voltage is being
interrupted and repair.
(16) Replace Start
Components
Before replacing, go to #17 to ensure compressor quality. Once
compressor checks okay, replace overload and relay.
(17) Check Compressor
Using Multi-meter, check compressor winding(s). For all models,
the resistance should be 20.9 ohms from common to start, and 5.5
to the run windings.
(18) Replace Compressor
Replace compressor if compressor windings are faulty. Always fol-
low established industry practices and applicable local, state and
federal laws regarding refrigerant handling.
