Carrier HH79NZ057 Thermistor
The Carrier HH79NZ057 Thermistor is a critical sensing component engineered specifically for low ambient control systems in Carrier, Bryant, and Payne condensing units. This thermistor monitors liquid line temperatures to provide precise feedback to the head pressure controller, ensuring stable refrigerant flow when operating in cooling mode during low outdoor temperatures. As a genuine OEM HVAC replacement part, the HH79NZ057 ensures accurate resistance-to-temperature conversion, preventing compressor cycling issues or evaporator coil freeze-ups. Designed for integration with Carrier fan speed controllers, this sensor features a durable thermistor bead and high-grade lead wires to withstand the vibration and thermal cycling common in outdoor environments. For technicians performing condenser fan motor troubleshooting or installing low ambient kits, verifying the resistance curve of the HH79NZ057 is essential for maintaining optimal subcooling and system pressure regulation across varying environmental conditions.
Key Technical Benefits- Precise Temperature Sensing: Calibration-matched for Carrier low ambient controls to ensure accurate head pressure management.
- OEM Compatibility: Exact fit for specific Carrier, Bryant, and Payne 38 series and 50 series units, eliminating the need for field modifications.
- System Protection: Critical for maintaining proper head pressure, preventing oil migration and thermal overload in low-temperature cooling applications.
- Rugged Construction: Built with high-quality moisture-resistant materials to prevent sensor drift or failure in high-humidity outdoor installations.
How do I test the HH79NZ057 for accuracy?
Using a multimeter set to the Ohms scale, measure the resistance across the leads and compare the reading to the Carrier thermistor temperature-resistance chart. Significant deviations or an open circuit indicate a failed sensor.
Where is this thermistor typically mounted?
In most low ambient kit installations, this thermistor is strapped to the liquid line near the condenser coil outlet to monitor the refrigerant temperature effectively.
Can this be used on non-Carrier equipment?
While thermistors operate on standard resistance curves, the HH79NZ057 is specifically calibrated for the control logic found in Carrier residential and light commercial HVAC systems.
