Maintenance: Sensors
Photo Eyes
The control that senses bin full and empty is a photo-

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.
