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.
