Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
INSPECTION
1. INSPECT AMBIENT TEMPERATURE SENSOR
a. Measure the resistance according to the value(s) in the table.
NOTE:
-
Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
-
When measuring, 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 is not as specified, replace the ambient temperature sensor.
