7.1.4 Replacing
To replace the control board:
1. Remove any shelving or product that will
interfere with accessing the inner ceiling of the
cabinet.
2. Once the inner ceiling is accessible, lower the
carbon filter housing by pulling on the front
edge to release the latch and mate connector
and remove the carbon filter.
3. Remove the wire channel cover in the left rear
corner by removing the fasteners holding it in
place.
4. Next remove the two (2) fasteners located
on the rear flange of the cover, that hold the
control cover panel to the ceiling. For the
freezer and wine models slide the cover back
a ½” to disengage the tabs that mate with the
user interface bracket. For the refrigerator, pull
forward on the cover to disengage the open
hem flange on the front of the cover.
5. Slowly lower the cover and remove the bushing
that protects the wires going through the wire
access hole.
6. Remove the wires through the key slot hole
and set the cover panel aside. The control
board is now visible. (If desired for the freezer
and wine models, the user interface can be
removed). ( See Section 7.2. ).
7. Disconnect all wire harnesses from the control
board, noting connecting locations if required.
8. Remove the 4 fasteners that hold the control
board to the ceiling (support the control
board).
9. Replace with new control board, installing in
reverse steps.
10. Ensure all electrical connections are correct and
properly engaged.
7.2 User Interface
If user interface is not operational, check electrical
connections from the control board to the user
interface. Use Control Replacing ( see section
7.1.4.) instructions to access the control board and
user interface connections. For a refrigerator, there
is a third connection located at the rear of the
user interface housing, to access, remove the deli
bin glass lid by removing the two pivot fasteners,
one on each end of the lid, then pull the two pins
on the edges of the user interface housing and
pull out on the housing. If connections are good,
replace the user interface assembly.
Replacing
Freezer and Wine
See Control Replacing instructions ( see section
7.1.4.). Once the control board is accessible,
remove the two fasteners, one on each inner
end of the user interface bracket. Slide the user
interface assembly forward to release the flange on
the front top. Once loose, disconnect the harness.
Replace following reverse instructions.
Refrigerator
The user interface housing is the complete sheet
metal housing that contains the user interface. To
remove the housing, remove the deli bin glass lid
by removing the two (2) pivot fasteners, one on
each end. Next, pull the two retaining pins from
the left and right edge of user interface housing.
Finally, pull out the housing, it will slide along the
rails, manage the wire harness and disconnect
before pulling completely out of the rails. Early
models may require removal of the left rear wall
cover panel to access the third connector. To
remove that panel, remove all shelving, remove
the center and left pilaster and finally remove
the panel. Locate the connector and disconnect.
Replace with a new user interface assembly
and complete user interface wire harness so the
connection is at the rear of the housing.
