Test Procedures

Photo-Eye Bin Control
Remove front panel.
Check controller code display. If the unit is in ice
making mode (status light on) there will normally
either be an F or a b displayed.
If the bin is full, b is displayed.
If the bin is not full and the unit is in ice making mode,
F is displayed.
if the bin is not full and the unit is off, O is displayed.
False bin full: If the bin is not full and b is displayed:
1. Check for loose connection at the harness to the
photo eye sensors.
2. Check for broken wire at sensor.
3. Check for something blocking the sensors, which
can include scale buildup.
Rotation Sensor
The sensor consists of a pick up and a magnet. The
pick up has a wire that connects to the controller. The
magnet is in the rotating magnet holder on top of the
auger motor. if the rotor is loose, it will not rotate and
the sensor will shut the machine off for no rotation.
1. Remove front and left side panels.
2. Remove motor cover.
3. Check that rotor has magnet and is secure to
motor shaft.
Note: Special thin open end wrench may be needed
to hold motor shaft, it fits under the magnet rotor.
Dispensing Motor
See chart on prior page.
Remove splash panel.
Place voltmeter probes on motor terminals.
Press Dispense Ice and confirm voltage. If voltage is correct and motor does not function, replace dispense
motor.
Note: 230 volt motor in an 115 volt machine will rotate with an empty bin but not one with ice. Be SURE to
confirm voltage on label to match ice machine voltage.
