Discharge Air Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: DUCT TEMPERATURE SENSOR: INSPECTION

INSPECTION





1. INSPECT DUCT TEMPERATURE SENSOR
(a) Remove the air duct sensor.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





NOTICE:
- Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
- When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph).
If the resistance value is not as specified, replace the sensor.
