Carrier 50HJ540570 Sensor

The Carrier 50HJ540570 Sensor is a critical OEM component designed for high-precision diagnostic and monitoring functions in commercial HVAC units. As a direct Carrier replacement air sensor, this part is engineered to integrate seamlessly with specific Carrier packaged rooftop units and split systems. Its low-mass design, weighing approximately 0.02 lbs, ensures a fast thermal response time, which is essential for maintaining accurate control of the refrigeration cycle and airflow parameters. This HVAC duct sensor serves as a fundamental data point for the system's logic board, allowing for real-time adjustments to cooling or heating stages. When your Carrier 50HJ540570 fails, it often leads to short-cycling or incorrect compressor staging, making a genuine OEM HVAC sensor the only reliable choice for service calls. For techs in the field, this thermistor-style sensor is the standard for restoring factory-spec performance in temperature-sensitive zones.

• Precise Electrical Resistance: Calibrated to provide exact feedback to the control board for optimized HVAC performance.
• Direct OEM Fit: Eliminates the mounting and wiring issues common with universal aftermarket thermistors.
• Durable Construction: Built to withstand the high-vibration environment of commercial fan coils and rooftop cabinets.
• Rapid Response: Low-inertia housing allows for near-instant detection of temperature fluctuations.

Is the Carrier 50HJ540570 compatible with all 50HJ series units?
While commonly utilized in 50HJ and 50TM rooftop series, compatibility depends on the specific wiring harness and control configuration. Always verify against the unit’s parts list.

How do I test if this sensor is faulty?
You should perform a resistance check using a multimeter and compare the Ohms to the temperature-resistance chart provided in the Carrier service manual for this specific part number.

Can this sensor be used for discharge air temperature monitoring?
Yes, depending on the controller’s programming, this sensor is often applied as a discharge air or return air temperature probe in various Carrier commercial layouts.
