Ranco 1309007-045 Sensor

The Ranco 1309007-045 Sensor is a critical NTC thermistor engineered specifically for seamless integration with ERC2 Series Controllers. As a veteran-grade temperature sensing component, it provides the precise feedback loop necessary for high-accuracy HVAC and refrigeration management. This OEM replacement sensor is essential for contractors maintaining single-stage packaged terminal units, through-the-wall heat/cool systems, and commercial refrigeration setups. By delivering consistent resistance values to the ERC2 control board, it ensures optimal compressor cycling and prevents evaporator freeze-ups, protecting expensive hardware from thermal stress.

Found primarily in demanding residential and commercial environments, this black NTC sensor features a robust 120-inch lead for versatile placement across various cabinet configurations. Its high-reliability construction is designed to withstand the rapid temperature fluctuations common in HVACR refrigeration units. Utilizing an ERC2 temperature sensor that meets original factory specifications is the only way to maintain the calibrated setpoints required for energy-efficient operation and stable climate control in temperature-critical applications.

• Precise NTC Thermistor Technology: Delivers accurate temperature resistance signals to ERC2 series controllers for tight differential management.
• Extended 120-Inch Lead: Provides ample length for remote sensing and flexible installation in large refrigeration evaporators or air handlers.
• Direct OEM Compatibility: Specifically designed to replace Ranco 1309007-045 and various cross-referenced Paragon sensors, ensuring no-drift performance.
• Broad Application Range: Optimized for use in PTAC units, room coolers, and commercial food service refrigeration equipment.

Is the 1309007-045 compatible with all ERC2 controllers?
Yes, this sensor is the standard thermistor for the entire ERC2 series, providing the specific resistance curve needed for accurate temperature decoding by the control board.

What are the symptoms of a failing Ranco sensor?
If your system is experiencing short-cycling, evaporator icing, or displaying "Sn" or "So" error codes on the ERC2 display, the sensor has likely failed or drifted out of calibration.

Can this sensor be used in -45°F environments?
This NTC sensor is rated for operation across a wide thermal spectrum, making it suitable for both standard HVAC and low-temperature refrigeration applications.
