Step 2: Remove top and middle shelves from upper compartment.
Step 3: Unscrew thermistor from left hand sidewall.
Step 4: Loosen both screws inside the front edge of control box (See figure 12.35). Insert a 5/16” nut
driver thru the located holes of the control box to reach the hex head screws. Loosen the screws
only for ease of re-assembling.

control box (See figure 12.36).
Step 7: Gently press down on the top, back edge of the plug and push away to disconnect.
Step 8: Remove both thermistor cables from the white “C” shaped nylon fasteners. This will give some
slack for the next steps.

between the channel top and the thermistor and communication cables.
Step 10: Gently press downward on the handle of the screwdriver. This will unlatch the channel seam
. Remove the screwdriver and continue opening the channel by running a finger along the open
seam towards the rear until completely unlatched.
Step 11: Remove the upper thermistor cable from the channel and remove from the black nylon “C”
fastener.
Step 12: Remove the thermistor cable.
Step 13: Reverse the above procedure to replace the new cable.
Step 14: When sealing the wire channel, make sure cables are not interfering and press upwards along
the channel edge to seal.
