Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
Outside Air Temperature Sensor Test
Dip the sensor in ice water, and measure the resistance. Then pour hot water on the sensor, and check for a change in resistance.
Compare the resistance reading between the No.1 and No.2 terminals of the outside air temperature sensor with the specifications shown in the graph; the
resistance should be within the specifications.
