ICE THICKNESS PROBE (HARVEST INITIATION)
How the Probe Works
Manitowoc’s electronic sensing circuit does not rely on
refrigerant pressure, evaporator temperature, water
levels or timers to produce consistent ice formation.
As ice forms on the evaporator, water (not ice)
contacts the ice thickness probe. After the water
completes this circuit across the probe continuously
for 6-10 seconds, a Harvest cycle is initiated.
Ice Thickness Check
The ice thickness probe is factory-set to maintain the
ice bridge thickness at 1/8 in. (3.2 mm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing
out of the water trough.
1. Inspect the bridge connecting the cubes. It should
be about 1/8 in. (3.2 mm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness or counterclockwise to decrease
bridge thickness.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16 in. (1.5 mm). The starting
point before final adjustment is approximately a 3/16 in.
