Checking Remote Temperature Sensor
(P/N 8301-095) Outside Unit Circuit
1. Disconnect temperature sensor from board.
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 ±1%.)
4. If sensor resistance reads very low, sensor is
shorted and will not allow proper control.
5. If sensor is out of tolerance, shorted, open or reads
very low ohms, it should be replaced.
