ClimateMaster 17B0031N01 Temperature Sensor

The ClimateMaster 17B0031N01 is a critical NTC thermistor designed for precision monitoring in water source heat pumps and geothermal HVAC applications. Featuring a 10K ohm resistance at standard calibration, this sensor provides the high-fidelity feedback necessary for CXM and DXM control boards to manage refrigerant temperatures and prevent low-temperature lockouts. This genuine OEM ClimateMaster part includes a 48-inch lead, allowing for versatile routing and secure attachment to heat exchanger or water loop components. For field technicians, the 17B0031N01 is the standard for resolving FP1 and FP2 sensor faults, ensuring the system accurately detects environmental conditions to optimize energy efficiency and equipment safety. By maintaining tight tolerances and a fast response time, this 10K temperature sensor ensures that your unit’s geothermal system controls operate without nuisance trips or calibration drift often found in generic replacements.

• Precise 10K Resistance: Calibrated specifically for ClimateMaster HVAC systems to ensure seamless integration with DXM2 and CXM controllers.
• 48-Inch Lead Length: Provides ample reach for refrigerant line mounting or air coil placement in compact heat pump cabinets.
• Reliable NTC Technology: Features a Negative Temperature Coefficient curve for accurate diagnostic feedback and high-accuracy thermal monitoring.
• Direct OEM Fit: Eliminates compatibility issues and wiring modifications often required with non-genuine HVAC temperature probes.

Is the 17B0031N01 compatible with all ClimateMaster units?
This sensor is widely used across water-to-air and water-to-water units using 10K thermistor inputs. Always verify your specific unit wiring diagram to ensure compatibility with the existing control board architecture.

What causes an FP1 or FP2 lockout code on the control board?
These codes typically indicate the 17B0031N01 sensor has detected a temperature outside of safe operating parameters or the thermistor itself has failed. Resistance testing against a temperature-to-ohm chart is recommended for diagnosis.

Can I extend the 48-inch lead if needed?
While leads can technically be extended, it is best practice to use the 17B0031N01 in its original length to maintain factory resistance values and prevent interference with the low-voltage signal.
