U-Line ULN-SS1095, SP 18 ICE Maker Operating Cycles U-CO29F Model, Freeze Cycle, Harvest Cycle

Section 3 - Service and Repair

ICE MAKER OPERATING CYCLES (U-CO29F MODEL)

Note: The refrigeration system operates independently of the ice maker. This is a new design for U-Line. All other U-Line ice makers use a double throw control system where the unit is either in a freeze mode or harvest mode. In the U-CO29FF, the refrigeration system will cycle on and off depending on the temperature of the freezer. In most cases, this means the refrigeration system will be operating during the ice making and harvest modes. If the freezer control is set too warm, the refrigeration system may cycle off during ice making mode, slowing the ice production rate. If this happens, adjust the freezer control colder.

Freeze Cycle

•Ice maker thermostat (located behind grille) open.

•Freezer control closed and refrigeration system is operating.

Harvest Cycle - 1

•Ice maker thermostat closed.

•Refrigeration system operating.

•If bin arm is up, the harvest will not initiate.

•Power goes through the bin switch to the ice maker motor and mold heater.

Harvest Cycle - 2

•Ice maker ejector blades reach 2:00 position and cam depresses the hold switch.

•Ejector blades stall on ice and ice maker motor pulsates until mold heater warms and ice releases.

•Refrigeration system operating.

Water Fill Cycle

•Ice maker blades reach approximately 10:00 position and cam depresses the water fill switch.

•Power to the water valve. Ice maker mold fills.

•Refrigeration system operating.

Eject Cycle

•Ejector blades push ice into bucket and stop at 12:00 position.

•Ice maker temperature control opens.

•Refrigeration system still operating.
