Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
AIR CONDITIONING: AMBIENT TEMPERATURE SENSOR (for Automatic Air Conditioning System): INSPECTION
1. INSPECT AMBIENT TEMPERATURE SENSOR
(a) Measure the resistance of the sensor.
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 result is not as specified, replace the ambient temperature sensor.
