STEP 3 INSTALL RUBATEX STRIP
• Remove 2 screws at the left side, 2 screws at the right
side and 1 screw going into the floor in front (5 total).
Lift off the diffuser case.
• Push the Rubatex foam shim (WR97X10098) into
position, between the left side wall and the air handler
assembly QC, as illustrated. The foam should align with
the front edge. DO NOT REMOVE PAPER BACKING.
STEP 4 REASSEMBLE PANELS,
COVERS AND SHELVES
• Reinstall any remaining Air Handler Assembly QC
screws.
• Reconnect the wiring harness.
• Reinstall the diffuser case assembly, the water tank
cover and the Climate Control drawer cover using all
original screws. Be careful not to damage the foam
plug that seals the wiring harness and water tubing.
• Reinstall the 2 screws through the Rubatex and into the
side wall. Check to be sure the damper moves freely
and is not obstructed by the Rubatex strip.
• Turn the Master Light Switch to off position. Tempo-
rarily reinstall Climate Control Drawer Cover. Connect
the wiring harness to the drawer.
• Plug in the power cord.
• Press Express Chill on the control panel. The dampers
should open and close or function as selected.
• Remove the freezer basket and shine a flashlight
through the air inlet duct or use a mirror to view
damper function. If dampers do not operate, replace
the Air Handler Assembly QC with the part number
specified for that model. ZIS360 – WR31X10023,
ZIS420 – WR31X10021, ZIS480 – WR31X10017. Shim any
new assembly with the Rubatex shim (WR97X10098) as
shown above.
Check for other possible problem areas:
• Check for gaps between the floor of the fresh food
compartment and the front of the Air Handler Assem-
bly. Seal any gap with RTV.
• Check FF1 and FF2 thermistor resistances at the J1
connector.
• Set temperature controls for fresh food at 37° and 0° in
the freezer.
• Check to make sure there are no food items at the back
of the top freezer basket that could block airflow. The
evaporator compartment airflow enters the freezer
from the back wall duct just over the top freezer
basket.
• Check for proper main FF damper function. The main FF
damper is located at the top of the FF compartment.
• Replace drawers and shelves.
• Reconnect power to refrigerator.
• Test controls on the Climate Control drawer.
• Turn Master Light Switch to the on position.
• Close the grille panel.
