Maintenance: Sensors
The control that senses bin full and empty is a
photo-electric eye, therefore it must be kept clean
so it can “see”. At least twice a year, remove the
ice level sensors from the base of the ice chute,
and wipe the inside clean, as illustrated.
1. Remove front panel.
2. Pull photo eye holders forward to release them.
3. Wipe clean as needed. Do not scratch the
photo-eye portion.
4. Return the eye holders to their normal positions
and return the front panel to its original position.
Note: Eye holders must be mounted properly. They
snap into a centered position and are properly
located when the wires are routed to the back and
the left eye is the one with 2 wires at the connector.
The ice machine senses water by a probe located
near the water reservoir. At least twice a year, the
probe should be wiped clean of mineral build-up.
1. Shut off the water supply.
2. Remove front panel.
3. Remove the hose from the water sensor, use a
hose clamp pliers for this.
4. Loosen mounting screw and release the water
sensor from the frame of the unit.
5. Wipe probes clean,
