Access
After removing the diffuser, the thermistor can be
accessed through the hole on the right-hand side of
the fan. After removing the thermistor from the clip
(on the inside of the fan housing), the thermistor
can be removed from the fan housing through the
hole in the top of the housing.
Note:
When installing the diffuser onto the fan
housing, the tabs must be on the bottom and the
flat surface must be on top. Incorrect installation
will prevent the drawer from cooling and warming
properly.
Note:
All thermistors can be checked using
Diagnostic Mode.
Refer to the Thermistor Values chart for resistance
values. Thermistor resistance can be checked at 2
places:
•
J5-5 to J5-6 at main control board. Connector J5 should be disconnected from main control board
when checking resistance.
•
9-pin connector located behind the Climate Control Drawer. Connector should be disconnected
when checking resistance.
5 VDC output to the thermistor can be checked at 2 places:
•
J5-5 to J5-6 at main control board.
•
9-pin connector located behind the Climate Control Drawer.
