Ice Sensors - Scotsman CME686 User Manual

Ice Sensors

The ice sensors, located in holders in the base of
the ice making section, must be clean and free of
mineral scale to provide the controller with
accurate information.
To clean them they must be removed from their
installed positions.
1. Remove front panel.
2. Push and release the Harvest button to release
ice. When ice quits falling, push and hold the Off
button until the machine stops.
3. If side access is available, remove both side
panels.
4. Remove evaporator cover.
5. Remove lower splash panel.
6. Remove inspection cover.
7. Remove cascading shield.
8. Locate sensor mounting holes, located at the
lower left and right corners of the freezing
compartment.
9. Push the sensors in at their mounting holes.
10. Reach in the freezing compartment and pull the
sensors out through the inspection hole until they
are at a comfortable distance from the cabinet.
11. Each sensor contains a removable tray. One
tray contains the infrared emitters, the other the
infrared receiver. Each lens must be clean and free
of scale for proper operation. The trays may be
removed from their holders for better access.
12. Push the tray in with a finger or thumb until the
tray flips out of its socket.

Ice Sensor Diagnostics
Diagnostics assume that the control system is
working but may not be able to sense cubes. Its
purpose is to determine which component may be
at fault - the controller or the ice sensors.
Unplug thermostat (if used) and check bin full light,
if off place an object between the ice sensors, after
5 seconds the Bin Full light will be glowing steadily,
if not check operation of sensors by unplugging #4.
Bin Full light will go on after 5 seconds, If not,
replace controller. If the light does go on, replace
ice sensor set.
