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.

Temperature (F) vs. Resistance (R) of Temperature Sensor
