ICE MACHINE DOES NOT CYCLE INTO HARVEST
Will not harvest symptoms
• Low ice production

times
If ice is on the evaporator initiate a manual harvest
cycle by performing the following keystrokes.
• Press Menu

arrow - A new freeze cycle will start after the
manual harvest cycle is complete.
NOTE: Ice must be off the evaporator before starting
the procedure.

control board, then reboot the control board by
disconnecting and reconnecting line voltage to the
ice machine.
2. Wait six minutes into the freeze cycle (timing
starts when the water pump energizes).
