Removal and Replacement: Fan Blade and/or Fan Motor

1. Disconnect electrical power.
2. Remove left front and top panels.
If stacked, removal is possible thru the front only.
Shut off the water and disconnect the inlet water
line from the solenoid valve. Move it up and out of
the way. Also remove the water pump to get better
access to the fan motor. Skip steps 3 and 4.
3. Remove the 4 screws holding the top part of the
fan shroud to the bottom fan shroud.
4. Tip the top of the fan shroud forward and pull it
up and out of the cabinet.
5. Note location of fan blade on shaft and loosen
fan blade set screw.
6. Remove the four bolts holding the fan motor to
the bracket.
7. Tip fan motor and blade up, move fan blade as
needed to clear internal parts.
8. Replace the blade or motor as needed.
Note: The fan is properly on the motor shaft when
the hub faces the motor and the shaft end is ½ "
from the fan blade.
Transformer and Compressor Starting
Components
Single phase compressors use a start relay, start
capacitor and run capacitor. All are located in a
sheet metal box to the right of the AutoIQ
Controller. The compressor contactor is also
located in that box.
1. Disconnect electrical power.
2. Remove left front panel.
3. Remove 2 screws at the front edge of the metal
box, and pull the cover forward and out.
4. To check components, reconnect electrical
power.
Note: The contactor coil is 24 volt.

Note: If the transformer is not supplying power,
check the AutoIQ Controller for blacking at the top
connections. If the connections appear to have
blacked, replace the AutoIQ Controller before the
transformer is replaced.
Discharge Line Temperature Sensor
1. Remove left front panel, push and release the Off
button.
2. Remove top and left side panels.
3. Locate discharge line sensor. It is attached to the
discharge line of the compressor, 6" from the
compressor discharge port.
4. Unwrap the insulation and un-snap the clip
holding the sensor to the discharge line.
5. Trace the sensor wires back to the controller,
they are plugged into #5 with the water temperature
sensor, and must be replaced with it.
6. Reverse to replace, be sure that the discharge
line sensor is 6" up from the compressor discharge
port. Be sure to re-wrap the insulation.
Note: Route wires so they do NOT contact the
discharge line.
The sensor for the Discharge line is marked
with a small piece of yellow tape. Do not
reverse the sensors.
