Control Board and Display
The control board and display are located in the
Climate Control Drawer top panel (mullion). The
control board and display are part of the mullion
and cannot be replaced separately.
Input from the Climate Control Drawer’s control
board and the thermistor is used by the main
control board to control the dampers, fan, and
heater.
Actual drawer temperature will be displayed in
Select Temp mode only. The Climate Control
Drawer display will show the selected temperature
for approximately 4 seconds after a Select Temp
mode has been selected. After approximately 4
seconds, the actual temperature of the drawer will be displayed.
The actual-temperature display is based on the temperature that the main control board sees from the
thermistor. The selected temperature (example: CITRUS – 43 °F) is based on the logic of the Climate
Control Drawer control board. If the actual temperature that is displayed is incorrect, the thermistor and
main control board are suspect. If the temperature associated with the Select Temp mode is incorrect,
the Climate Control Drawer control board is faulty.
