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,
Check Gear Reducer Lubricant
Although there is no normal access to the gear
reducer lubricant, it can be checked without removal
and complete disassembly. The auger drive motor
must be removed and the lubricant checked through
the input shaft area.
Because of a shelf under the motor hole, only about
3/16 of oil should be on the tip of the screwdriver
blade. Any more and there may be water in the gear
case, any less and it may be low. The correct oil
charge is 14 ounces.
