ClimateMaster S17S0031N01 Thermistor
The ClimateMaster S17S0031N01 Thermistor is an essential OEM temperature sensor specifically engineered for AirFreeze protection in geothermal and water-source heat pump systems. This replacement thermistor features a 10K Ohm NTC sensor calibrated to provide precise resistance feedback to the CXM or DXM control board. With its 48-inch violet lead, this sensor ensures accurate monitoring of the refrigerant line temperature at the air coil (FP2/LT2 location), effectively preventing evaporator freeze-ups and nuisance lockouts. As a direct HVAC replacement part, it is designed for a seamless fit, matching the exact specifications of older part numbers including 17B0005N02 and 17B0027N02. For technicians troubleshooting fault code 5 (Air Coil Low Temperature), this genuine ClimateMaster sensor provides the high-sensitivity thermal response required to maintain unit efficiency and protect the compressor from liquid slugging during low-airflow or low-ambient cooling cycles.
Key Benefits for Technicians:
- OEM Precision: Genuine ClimateMaster S17S0031N01 ensures the 10K Ohm resistance curve matches the control board logic for accurate freeze protection.
- Extended Reach: Features a durable 48-inch violet lead for flexible installation across various cabinet sizes and coil configurations.
- Direct Cross-Reference: Effortlessly replaces legacy part numbers 17B0005N02, 17B0027N02, and 17B0031N01 without field modifications.
- System Reliability: Protects against FP2 low temperature faults, preventing system downtime and ensuring optimal refrigerant cycle monitoring.
- Standardized Mapping: Color-coded violet leads allow for immediate identification at the 12-pin harness, simplifying diagnostic trace-outs.
Common Questions:
What does the violet wire color signify?
In ClimateMaster systems, the violet lead signifies the FP2 or LT2 sensor, which typically monitors the air coil temperature to prevent freezing. This is distinct from the gray-leaded FP1/LT1 sensor used for the water coil.
How do I test if this thermistor is defective?
Measure the resistance across the sensor leads using an ohmmeter while it is disconnected from the CXM or DXM board. Compare the reading to a standard 10K Ohm NTC chart; if the resistance is significantly higher or lower than the ambient temperature equivalent, the sensor is out of calibration and needs replacement.
Will this sensor clear a Code 5 lockout?
If the lockout is caused by a drifting or failed thermistor that is falsely reporting low temperatures, installing the S17S0031N01 will resolve the issue. However, always verify airflow and refrigerant charge to ensure the lockout isn't triggered by actual low-temperature conditions.
