Moisture migration into door foam may cause
dispenser tube to freeze, resulting in no water
dispensed.

REPAIR/RESOLUTION
Install service kit WR49X10173, dispenser heater.
• Remove the board and cradle assembly from the dispenser housing.
• The heater will be applied to the recessed area below the ice duct door. Note: Clean and dry this area as thoroughly as possible.
• Peel the paper backing off of the heater and apply it in the recessed area below the ice duct door. Press firmly over the entire surface to ensure adequate adhesion, forming it around the dispenser tube as necessary.
• Route the white lead wires to the dispenser housing to the left of the ice duct door, as shown, to prevent the wires from interfering with the duct door. Make sure the wires do not interfere with ice/water path or movement of the duct door.
• Connect heater wires to wire harness using the red fold-over splices provided. Do not cut wires on the unit. If there is no heater already installed on the ice duct door, attach heater wires to the red wire on pin 2 and black wire on pin 6 as shown in the figure at right below. If there is an ice duct door heater kit installed, the instructions for the kit specify a different method that must be used to properly attach
the heater.

Installation Instructions
Supersedes All Previous Instructions
This service part must be installed by the technician.
Pub. No. 31-46112
Part No. 197D7768P001
* NOTE: This kit is specifically designed for refrigerator
models with metal liners.
Prior to Installation, please verify “no water dispense”
is root caused to frozen water line. The quickest way to
determine if the failure is due to a frozen water line is to
first ensure that water does NOT dispense. Next, disconnect
the blue connector at the bottom of the door and
ensure that water flows when the paddle is pressed. Use
a cup/container to avoid a water spill while conducting
this test.
1. Remove the board and cradle assembly from the dispenser
housing.
2. The heater will be applied to the recessed area below
the ice duct door. See Figure 1. Clean this area as thoroughly
as possible.
3. Peel the paper backing off of the heater and apply
it in the recessed area below the ice duct door. See
Figure 1. Press firmly over the entire surface to ensure
adequate adhesion, forming it around the dispenser
tube as necessary.
4. Route the heater lead wires to the dispenser housing
to the left of the ice duct door, as shown in Figure 1, to
prevent the wires from interfering with the duct door.
5. Connect heater wires using the red fold-over splices
provided. Do NOT cut wires on the unit; instructions for
proper use of splice connectors are below. Depending
on how the refrigerator is equipped, there are two
methods for installation:
If there is NO heater kit installed on the ice duct door,
attach heater wires to red wire on pin 2 and black and
white wire on pin 6. Attach splices 1” from the grommet
where the wires come out of the top of the dispenser
recess. See Figure 2.
NOTE: Red splice connectors (included in kit) are for
Low Voltage DC only.

Splice Here
If there IS a heater kit installed on the ice duct door, attach heater wire leads of this kit to the wire leads from the ice duct door heater 2” from the splice connectors that attach the ice duct door heater to the wires on pins 2 and 6. Ensure that the wires are not interfering with the ice duct door, and that ice has an unrestricted path into the dispenser recess area. If possible, bunch up the excess wire leads from both heaters and use a wire tie to keep them together and out of the way. Leave enough slack in the leads to allow for proper function of the ice duct door and for reconnection of the wires to the control board. See Figure 3.
To properly use each red splice connector, position the heater wire into the side of splice connector that does not allow the wire to pass all the way through: Insert the appropriate wire (from pin 2/6) into the other side of the splice connector. Hold the wires securely in place before crimping the metal conductor gate on the splice connector using pliers. Avoid using too much force, but crimp until the metal gate conductor is flush with the red plastic housing. Complete the connection by folding the red plastic flap over the crimped metal conductor gate. See Figure 4.
6. Check heater functionality using your finger to ensure heater is warm after approximately one minute after connecting the heater wires. To get power to the heater, temporarily plug the 6-prong connector into the control board.
7. Replace dispenser cradle assembly and control board. See Figure 5 for wire routing.
* NOTE: It could take up to a day for the heater to thaw ice/enable water to flow properly from the dispenser.
