CHECKING TEMPERATURE SENSOR

1. Disconnect temperature sensor from board and

from outdoor coil.

2. Use an ohmmeter and 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 then it should be replaced.
