Action
Check the flag for correct operation, binding, broken parts, or
interference from the sensor cable. If incorrect, repair as necessary. If
correct, make sure the bottom pass thru sensor is correctly
connected to J5 on the control board. Disconnect the pass thru
sensor cable and check the voltage at J5-3. The voltage measures
approximately +5 V dc. If incorrect, check the voltage at J5-2. The
voltage measures approximately 0 V dc. If incorrect, replace the
sensor assembly. If this does not fix the problem, replace the control
board.
Action
Check the flag for correct operation, binding, broken parts or
interference from the sensor cable. If incorrect, repair as necessary. If

sensor cable and check the voltage at J11-3 The voltage measures
approximately +5 V dc. If incorrect, check the voltage at J11-2. The
voltage measures approximately 0 V dc. If incorrect, replace the
sensor assembly. If this does not fix the problem, replace the lower
