Ambient Temperature Sensor / Switch HVAC: Testing and Inspection

AIR CONDITIONING: AMBIENT TEMPERATURE SENSOR: INSPECTION

INSPECTION





1. INSPECT AMBIENT TEMPERATURE SENSOR
(a) Measure the resistance.
Standard resistance:





NOTICE:
- Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
- When measuring the resistance, the temperature of the sensor and the ambient temperature sensor must be the same.
HINT: As the temperature increases, the resistance decreases (see the graph).
