Ice Machine Does Not Cycle Into Harvest
when Water Loses Contact with the
Harvest Float Switch
NOTE: The ice machine will make a thick or double
slab when a new freeze cycle is started with ice
already present on the evaporator.
Two of the most common scenarios are:
• Power is cycled off/on with ice on the evaporator.
• The water curtain/bin switch is opened/closed in
the harvest cycle before the ice releases.
Remove all ice from the evaporator before starting
diagnostic procedures.
Freeze Time Lock-In Feature
The ice machine control system incorporates a freeze
time lock-in feature. This prevents the ice machine
from short cycling in and out of harvest. The control
board locks the ice machine in the freeze cycle for six
minutes. After six minutes a harvest cycle can be
initiated. To allow the service technician to initiate a
harvest cycle without delay, this feature is not used on
the first cycle after moving the toggle switch to OFF
and back to ON.
