Temperature Control Actuator Inspection
S7RS0B7226005
1) Remove temperature control actuator from HVAC
unit referring to “Temperature Control Actuator
Removal and Installation”.
2) Connect connector to temperature control actuator.
3) Set temperature selector of HVAC control module to
MAX HOT position with ignition switch ON, and
make sure if the position of actuator lever is MAX
HOT position (A).
4) Turn ignition switch OFF, and then disconnect
connector from temperature control actuator.
5) Measure resistance between terminal “3” and “5”.
Temperature control actuator resistance between
terminal “3” and “5” (MAX HOT position)
Approximately 2.5 kΩ at 25°C (77°F)
6) Connect connector to temperature control actuator.
7) Set temperature selector of HVAC control module to
MAX COOL position with ignition switch ON, and
make sure if the position of actuator lever is MAX
COOL position (B).
8) Turn ignition switch OFF, and then disconnect
connector from temperature control actuator.
9) Measure resistance between terminal “3” and “5”
Temperature control actuator resistance between
terminal “3” and “5” (MAX COOL position)
Approximately 4.8 kΩ at 25°C (77°F)
If check result is not satisfactory, replace the actuator
with new one.
