6 New Features Dual Ice Makers 7 cube Flex Tray Type Ice-Maker (Freezer) 10 cube Direct Cool Heated Mold Type Ice-Maker (Refrigerator)

7 New Features Extra refrigerant loop connected to the refrigerator evaporator coil for the direct cooling ice maker in the ice room of the refrigerator Compressor CondenserHot PipeBack Cluster Pipe DryerCapillary TubeRefrigerator Evaporator Direct Cool I/M Freezer EvaporatorSuction PipeCompressor

8 New Features Ice room cooling fan is now in the auger motor housing instead of the freezer

9 New Features There is no longer an ice full detector arm that comes down from the ice maker. Instead there is an infrared transmitter and receiver system that detects the level of ice in the bucket. The I/R transmitter is in the auger motor housing and the receiver is in the ice maker itself. I/R Transmitter (auger motor) I/R Receiver (ice maker)

10 New Features New left side refrigerator door vertical hinged section The vertical hinge attached to the left side door of the refrigerator has a moveable, spring loaded, latch at the top of it that allows the door to be closed even if the hinge is in the wrong position

11 New Features The ambient and humidity sensors as well as the dispenser lock out switch are now located on top of the left side refrigerator door instead of under the hinge plate. This eliminates the need for extra wiring connectors in the event the door needs to be removed. Ambient sensor Dispenser lock out switch Humidity sensor

18 Refrigerator Ice Maker Removal Latch While pressing the latch on the top right side of the ice bucket, lift up the bucket and pull it out

19 Refrigerator Ice Maker Removal Once the ice bucket is removed there is a caution that must be observed before attempting to remove the direct cooling ice maker.

20 Refrigerator Ice Maker Removal To enter the forced mode, press and hold these 2 buttons on the display panel until the display blanks out. Then press any button until Fd appears on the display. This indicates the freezer section as well as the refrigerator section is in the defrost mode.

21 Refrigerator Ice Maker Removal While in the forced defrost mode for both refrigerator and freezer compartments, Fd, start disassembling the I/M. Remove the screw from the wire housing cover and remove the cover. With the power disconnected, unplug the I/M connector. Ice Maker Connector Auger Motor Connector

22 Refrigerator Ice Maker Removal Remove the silicone cap covering the lower I/M cover and remove the screw

23 Refrigerator Ice Maker Removal Using a flat blade screw driver, pry the latch on the left side of the lower I/M tray to release the tray. Once released CAREFULLY pull the tray down. It will not come out as the rear of the tray is attached to the I/M.

24 Refrigerator Ice Maker Removal If the I/M was not allowed enough time to defrost ice build up, the lower tray and/or the cooling tube can be damaged. Cooling Tube

25 Refrigerator Ice Maker Removal CAREFULLY insert a flat blade screwdriver between the cooling tube and the mold of the I/M and pull the tube down

26 Refrigerator Ice Maker Removal While pressing the latch on the I/M, pull out and down to remove the Ice Maker. When removing the I/M, be sure that the cooling tube grommets (6ea) are not removed and the tube is not damaged.

27 New Refrigerator Ice Maker Design Function test button I/R Receiver Water duct drain Ice cube sweep arms FRONT There are no replaceable components on this ice maker. It should be replaced as an assembly.

28 New Refrigerator Ice Maker Design Bottom view of the new direct cooling I/M without the water duct drain. The heater is part of the mold but the cooling tube is moved out of the way to remove the I/M from the ice room. When replacing the ice maker the cooling tube MUST fit into the channel provided in the mold or the bottom cover will not close and the mold will not cool properly affecting ice production. I/M mold Mold heater Mold cooling tube

29 New Auger Motor Assembly Ice room cooling fan duct I/M defrosted water drain BLDC Fan Ice bucket full I/R transmitter Ice room temperature sensor

30 Auger Motor Removal Ice Maker Connector Auger Motor Connector Unplug the auger motor connector. NOTE: The ice maker must be removed in order to remove the auger motor

31 Auger Motor Removal With the auger motor assembly unplugged, press on the latch on the bottom of the assembly to unlock it and slide the assembly out

32 Auger Motor Fan Removal Ice room circulation fan Ice maker drain Ice Room Fan Error

33 Auger Motor Fan Removal With the auger motor removed, take out the screws that holds the drain in place and move the drain and Styrofoam insulation away.

34 Auger Motor Fan Removal With the Styrofoam insulation removed both the ice maker drain with heater and the fan can now be removed for replacement. Both components are using connectors that unplug.

35 Non Replaceable Auger Motor Components If any of these components in the auger motor assembly fail, the entire assembly should be replaced: Auger motor Solenoid Ice room temperature sensor I/R transmitter The fan and drain heater can be replaced with minimal disassembly.

36 Detecting the I/R Transmitter The ice bucket level I/R transmitter, located in the auger motor assembly, will not throw an error if it fails. To detect if it is working, view the I/R LED through any camera or most any phone that has a camera and you will see it lit.

37 Ice Room Component Errors Ice Room Sensor Error Sensor housing cracked or broken, wiring problem or sensor is shorted or open. Refrigerator Ice Maker Function Error Error is displayed when a Heater opens or the ice maker does not function properly. Separation of Ice Pipe Heater housing, Connection problem or open heater Ice Room Fan Error Error occurs during operation if the feedback signal is not received from the fan motor. Defective fan, connection or main PCB. Only the fan and drain heater, located in the auger motor housing, can be replaced. All other errors require the assembly be replaced.
