  • Page 7: Section One

    SECTION ONE INSTALLATION CONSIDERATIONS LOCATION The ice maker may be closed in on the top, rear and two sides. The front MUST BE unobstructed for proper air circulation and operation. Installation should be such that the unit can be moved forward for servicing. The installed area should be well ventilated, with ambient temperatures above 55°F (13°C) and below 110°F (43°C).

  • Page 9: Section Two

    SECTION TWO THEORY OF OPERATION OPERATING SYSTEMS There are three operating systems in the ice maker: • Refrigeration System • Water System • Electrical System Refrigeration System The refrigeration system in the ice maker is very similar to the system used in other refrigeration appliances such as a refrigerator or freezer.
  • Page 10 Water System The water system provides the fresh water necessary for ice production and recycling this water as ice is produced. The water system also flushes away rejected minerals and contaminates, circulates cleaning solution during the CLEAN CYCLE and provides a means of drainage. The hardness of the water supplied to the ice maker will affect the quality of the ice produced and may also affect the operation of the water system.
  • Page 11 ELECTRICAL SYSTEM The ice maker’s electrical system provides power for the refrigeration and water systems to operate, and controls the operational cycling of the ice maker. Wiring Diagram shows unit in Ice Making Mode...
  • Page 12: Operational Cycles

    OPERATIONAL CYCLES There are three operational cycles of the ice maker: • ICE MAKING CYCLE • HARVEST CYCLE • DIAGNOSTIC/CLEAN CYCLE In addition, there are two operational OFF cycles of the ice maker: • OFF CYCLE when the bin is full of ice and the service control switch is turned “ON”. •...
  • Page 13 Harvest Cycle Electrical System In the electrical system, when the set temperature of the evaporator thermistor is reached, the evapo- rator thermistor terminates power to the condenser fan and water recirculating pump, and supplies power to the hot gas valve solenoid and the water fill valve solenoid. Refrigeration System In the refrigeration system, the hot gas valve opens, allowing high pressure refrigerant gas to bypass the condenser and flow through the condenser accumulating tube.
  • Page 14 Clean Cycle Electrical System In the electrical system, power is supplied to the water recirculating pump through the service control switch. Water System In the water system, water recirculating pump circulates the cleaning solution that has been added to the reservoir up to the distributor, across the evaporator, and back into the reservoir where it is recir- culated while the service control switch is in the “CLEAN”...

  • Page 16: Accessing The Control Box

    The control box is located behind the door on automatic ice makers with full length doors. (Fig. 3-1) Control Fig. 3-1 Models with Shorter Length Doors (Whirlpool) The control box is located behind the control box es- cutcheon above the door on automatic ice makers with shorter length doors.
  • Page 17: Accessing Component In The Control Box

    ACCESSING THE COMPONENTS IN THE CONTROL BOX (This procedure is the same for long and short door units.) Removing the Control Box Remove the three (3) Phillips-Head screws securing the cutter grid cover to the cutter grid. (Fig. 3-2) Three (3) Screws Wiring Harness Plugs Fig.
  • Page 18 Removing the Electronic Control Board With the control box in the service position, disconnect the three (3) wiring harness plugs from the connectors on the electronic control board. (Fig. 3-9) Remove the two (2) Hex-head screws securing the electronic control board to the mounting stubs in the control box.
  • Page 19: Accessing The Component Compartment

    ACCESSING THE COMPONENT COMPARTMENT Open the ice maker door and remove the four (4) Phillips-Head screws securing the component compartment front cover to the cabinet. (Fig. 3-14) Pull the ice maker from its installed Screws position. It may be necessary to disconnect the water supply line and drain line from the ice maker.
  • Page 20 Removing the Water Valve The water valve can be serviced with the unit in the installed position by removing the component compartment cover. Disconnect the wiring harness connector from the water valve solenoid terminals. Disconnect the water supply lines from the inlet and outlet of the water valve.
  • Page 21: Section Four

    SECTION FOUR TROUBLESHOOTING AND DIAGNOSTICS WATER AND ITS EFFECT ON ICE MAKING Quality ice is defined as hard, clear, cold and free of taste or odor. All ice makers will provide this type of quality ice only if the water used to produce the ice is pure and free of mineral or chemical contami- nation.
