Section 50 - Climate Control - Chapter 1
The cab temperature sensor must be installed in the
recirculation air stream which enters the HVAC box at
the rear. Do not install the sensor in contact with any
metal surface; see illustration for view from inside the
HVAC box.
Since the cab temperature sensor is located behind
the recirculation air filter, any obstruction in the return
air path will reduce system performance: The sensor
will only detect air temperature in the HVAC box and
not the true cab air temperature.
Check the area behind the operator's seat for
obstructions at the recirculation filter, and check the
RI03B039
filter for cleanness before testing the sensor.
