ClimateMaster 17B0030N04 Thermistor
When you are troubleshooting a ClimateMaster geothermal system with a locked-out compressor or a sensor fault, precision matters. The ClimateMaster 17B0030N04 Thermistor is a genuine 10K Blue Thermistor Sensor designed for critical temperature monitoring in residential and commercial water-source heat pumps. This OEM sensor provides real-time data to the microprocessor, ensuring the EarthPure HFC-410A refrigerant circuit stays within safe operating parameters. Whether used as a water coil low temperature sensor or an air coil temperature sensor, this unit prevents freezing and pressure spikes that lead to premature equipment failure.
Replacing a failing thermistor with this exact ClimateMaster replacement part restores the unit's ability to communicate with the HVAC control board accurately. As a veteran-grade geothermal HVAC part, it is engineered to withstand the moisture and cycling common in high-efficiency heat pump systems. Field-testing shows that using these specific blue-coded sensors reduces nuisance trips and ensures the refrigerant metering and safety controls operate exactly to factory specifications.
Technical Benefits:
- OEM Reliability: Ensures total compatibility with ClimateMaster geothermal units and microprocessor controls.
- Precise Monitoring: The 10K ohm resistance curve provides high-accuracy temperature feedback to prevent freeze-ups.
- Optimized Performance: Maintains system efficiency by providing reliable data for safety sequences and defrost logic.
- Durable Construction: Specifically designed for the harsh environments found in coaxial heat exchangers and air coils.
Common Questions:
- Can I use this blue thermistor to replace a gray or red one? No. ClimateMaster sensors are color-coded to designate specific resistance curves and cable lengths; always replace by the specific part number 17B0030N04.
- Where is this sensor typically located? It is commonly mounted on the refrigerant lines or the water-to-refrigerant heat exchanger to monitor for low-temperature conditions.
- What are the symptoms of a faulty 17B0030N04 sensor? Typical indicators include "Fault" codes on the control board, compressor lockouts, or inaccurate air/water temperature readings during a diagnostic check.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
