Water Tank  

To remove the water tank:

1.  Remove the vegetable and fruit drawers shelf. 

(See 

Vegetable and Fruit Drawers Shelf

.)

 

2.  Remove the pantry drawer. (See 

Pantry Drawer

.)

 

3.  Remove the 2 Phillips-head screws that attach 

the water tank assembly to the back wall of the 
refrigerator section.

4.  Carefully pull the right side of the tank assembly 

approximately 5 inches out from the back wall.

5.  Disconnect the water tank heater wire harness. 

Note:

 

•  The water tank heater is 13 VDC and only turns 

on when the fresh food thermistor reads below 

35°F. The tank heater resistance is 72 

Ω

 and can 

be read from the main board CN79 pin 2 to pin 6, 
or at the water tank heater wire harness. 

•  The water tank heater is attached to the tank 

cover with a recessed Phillips-head screw. 

6.  Remove the Phillips-head screw that attaches 

the water tank heater to the cover.

7.  Note the routing of the tank inlet, connector, 

and outlet tubes. Remove the tubing and tanks 
from the cover.

8.  Remove the John Guest clip from each coupler. 

Push in the rear collar on the water coupling 
and pull out the water tube.

Note:

 The tank inlet and outlet tubes are routed 

through separate conduits placed inside the cabinet 
wall.
