Daikin-McQuay 6023970 Thermistor

The Daikin-McQuay 6023970 Thermistor is a precision HVAC temperature sensor engineered for high-accuracy thermal monitoring within commercial cooling and heating systems. As a critical component for Daikin Applied and legacy McQuay equipment, this NTC thermistor provides real-time resistance feedback to the unit controller, ensuring optimal compressor staging and discharge air temperature control. Its rugged construction is designed to withstand the high-vibration environment of internal air handler and chiller compartments. When diagnosing short-cycling or inaccurate sensor readings, this OEM HVAC replacement part ensures the control board receives stable data, preventing sensor drift and maintaining system efficiency. For contractors performing preventative maintenance or emergency repairs, verifying the 6023970 resistance chart against actual ambient temperatures is essential for troubleshooting circuit board errors or diagnostic fault codes in commercial HVAC systems.

• Precise Thermal Feedback: Delivers accurate resistance-to-temperature conversion for tight system tolerances.
• Durable Housing: Built to resist moisture ingress and thermal cycling common in chiller applications.
• Direct OEM Fit: Ensures seamless integration with Daikin-McQuay controllers without requiring calibration adjustments.
• Operational Stability: Reduces the risk of false high-pressure trips or freeze-stat activations by providing reliable data points.

What are the symptoms of a failing Daikin 6023970 thermistor?
Technicians usually identify failure through erratic temperature readings on the human-machine interface (HMI), "open circuit" fault codes, or the unit failing to acknowledge cooling demands despite acceptable ambient conditions.

How do I test this sensor in the field?
Isolate the sensor and use a multimeter to measure the DC resistance (Ohms) across the leads. Compare the reading to the Daikin technical specifications resistance curve for the current sensed temperature.

Is this thermistor compatible with non-Daikin controllers?
This part is specifically calibrated for Daikin-McQuay control logic. Utilizing this sensor with third-party controllers may result in inaccurate scaling unless the resistance curve is identical.
