ClimateMaster 17B0008N01 Thermistor
The ClimateMaster 17B0008N01 Thermistor is a critical 10kΩ NTC (Negative Temperature Coefficient) sensor engineered for pinpoint thermal feedback in geothermal and water-source heat pump assemblies. As a veteran-grade HVAC replacement part, this thermistor is essential for monitoring refrigerant line temperatures, preventing nuisance lock-outs on CXM and DXM control boards. With a standard operating range of -40°C to 85°C and an accuracy tolerance of ±1°C, it provides the precise resistance-to-temperature data required to manage FP1 (water coil) and FP2 (air coil) protection circuits. Utilizing high-stability internal elements, the 17B0008N01 sensor ensures your system maintains thermal equilibrium, mitigating common Fault Code 4 and Code 5 errors caused by out-of-calibration sensing. This OEM ClimateMaster part is designed for direct integration into existing wire harnesses, providing the fast response time necessary for high-efficiency commercial and residential climate control systems.
Key Benefits:- Precise 10kΩ NTC Curve: Engineered specifically for ClimateMaster heat pump logic to ensure accurate resistance-to-temperature conversion.
- System Protection: Critical for monitoring liquid line and evaporator temperatures to prevent coil freezing and compressor damage.
- Direct OEM Compatibility: Minimizes diagnostic time by providing a standard fit for 12-pin control board harnesses in CXM/DXM-equipped units.
- Enhanced Stability: High-grade construction reduces thermal drift, preventing the "swapped thermistor" (Code 9) and "low temperature" (Code 4/5) nuisance trips.
How do I test the ClimateMaster 17B0008N01 thermistor?
Disconnect the sensor and measure resistance with a multimeter set to the kΩ scale. At 77°F (25°C), the reading should be 10kΩ. If the value deviates significantly from the standard NTC chart, the sensor is out of calibration and needs replacement.
What causes a Code 4 or Code 5 lockout on my geothermal unit?
These codes often indicate that the FP1 or FP2 sensors are detecting temperatures below safe thresholds. If water flow and air filters are verified, a failing 17B0008N01 thermistor with high resistance is the likely culprit, falsely signaling a low-temperature condition to the board.
Where are these thermistors typically located in the system?
The FP1 (gray wires) is located on the refrigerant line between the expansion valve and the water coil, while the FP2 (violet wires) is positioned between the expansion valve and the air coil.
