Carrier RC6600035 Thermistor

The Carrier RC6600035 Thermistor is a critical OEM replacement sensor engineered for precision monitoring of entering and leaving water temperatures in commercial chiller systems. As a veteran-grade HVAC temperature sensor, this unit is the direct factory-authorized upgrade for the obsolete 30RB660036, ensuring seamless integration with existing Carrier chiller controllers and Pro-Dialog+ systems. Designed to withstand the rigorous demands of industrial fluid loops, the RC6600035 provides high-accuracy thermal resistance data to the main base board, preventing common system faults such as evaporator freeze-up or inefficient head pressure regulation. This 5k ohm thermistor (at 25°C/77°F) is essential for maintaining design-specified delta-T across heat exchangers. By replacing failing water temperature sensors with this genuine Carrier part, contractors can eliminate erratic cycling and restore optimal refrigerant subcooling and suction superheat calculations. The ruggedized lead wires and moisture-resistant bulb construction are purpose-built for both closed-loop water systems and brine solutions in demanding HVACR environments.

• Direct OEM Compatibility: Serves as the factory replacement for 30RB660036 and 00PPG000008105A, eliminating field modification needs.
• Enhanced System Accuracy: Delivers precise ambient and fluid temperature feedback to prevent unnecessary low-pressure trips.
• Industrial-Grade Reliability: Engineered specifically for Carrier 30RB, 30XA, and 30XV series chillers, ensuring long-term signal stability.
• Optimized Energy Efficiency: Enables the control board to manage compressor staging effectively by accurately tracking chiller outlet temperature.

Is the RC6600035 compatible with older 30RB series chillers?
Yes, the RC6600035 is the direct engineering replacement for the older 30RB660036 part number and is fully compatible with the Carrier 30RB chiller logic boards.

What are the symptoms of a failing water temperature thermistor?
Common indicators include erratic leaving water temperature readings on the interface, frequent "Loss of Flow" or "Freeze Protection" alarms when flow is present, and inconsistent compressor staging.

Does this sensor require calibration after installation?
This is a plug-and-play OEM component. As long as the sensor is seated correctly in the thermowell with appropriate thermal paste, the carrier control system will recognize the resistance curve automatically.
