CHECKING TEMPERATURE SENSOR
OUTSIDE UNIT CIRCUIT

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.
