Removal and Replacement: Fan Blade and/or Fan Motor
1. Disconnect electrical power.
2. Remove front, top and side panels.
3. Remove the 4 cap screws holding the fan motor
bracket to the condenser shroud.
4. Unplug the fan motor.
5. Carefully remove the fan motor, blade and
brackets from the ice machine cabinet.
6. Replace the motor or blade as needed.
Note: The fan is properly on the motor shaft when
the hub faces the condenser and the shaft is flush
with the end of the hub.
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 system
controller. The compressor contactor is also
located in that box.
1. Disconnect electrical power.
2. Remove 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 system controller for blacking at the top
connections. If the connections appear to have
blacked, replace the system controller before the
transformer is replaced.
Discharge Line Temperature Sensor
1. Remove 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.
