Harvest Cycle

REMOTE CONDENSER

The head pressure control cycles into full bypass due

to the pressure drop when the harvest valve opens.

Refrigerant flows from the compressor to the

evaporator through the harvest valve and the head

pressure valve is out of the circuit.

Undercharge Symptoms

• Safety limit #1 or Safety limit #2 in control board

memory.

• Harvest cycle suction pressure is low.

• Harvest cycle discharge pressure is low.

• Liquid line entering receiver feels warm to hot in

the freeze cycle.

Overcharge Symptoms

• Safety limit #2 in control board memory.

• Harvest cycle suction pressure is low.

• Harvest cycle discharge pressure is normal.

• Freeze cycle time, suction and discharge pressure

are normal and the ice machine will not harvest.

The sheet of ice cubes show little or no sign of

melting when removed from the evaporator after

the harvest cycle has been completed. (If the

cubes are melted you have a release problem,

clean the ice machine).
