CHECKING TEMPERATURE SENSOR

1.  Disconnect temperature sensor from board and 

from outdoor coil.

2.  Use an ohmmeter to measure the resistance of the 

sensor.  Also use ohmmeter to check for short or 
open.

3.  Check resistance reading to chart of resistance use 

sensor ambient temperature.  (Tolerance of part is 
±10%.)

4.  If sensor resistance reads very low, then sensor is 

shorted and will not allow proper operation of the 
heat pump control.

5.  If sensor is out of tolerance, shorted, open or reads 

very low ohms, it should be replaced.
