Checking Temperature Sensor Outside

Unit Circuit

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, 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.
