
Sensor Errors are generated when the MAIN PCB sees the sensor as either
open or shorted.

From the applicable connector at the Main PCB check for dc voltage to the
sensor (0 or 5 Vdc would indicate a shorted or open Sensor) or disconnect
power to the refrigerator and check resistance (0 or
∞ ohms indicate a shorted
or an opened sensor). If sensor failed, check the exposed Sensor wire
connections outside of liner to determine if the wiring in the cabinet is the issue.

With the exception of the
Pantry, Room and Humidity Sensors,
all sensor
errors will be displayed after the 3 Hour hold window. To bring up the errors
sooner then the 3 hour window or to display the error exceptions, “
Press and
hold the Freezer and Ice Plus buttons together. “
