Daikin-McQuay 2228741 Thermistor Assembly
When you are troubleshooting a Daikin error code C4 or dealing with erratic discharge air temperatures on a commercial split system, the Daikin-McQuay 2228741 Thermistor Assembly is the critical OEM replacement part required to restore precision. This HVAC temperature sensor is engineered as a high-accuracy negative temperature coefficient (NTC) component, delivering real-time resistance feedback to the Daikin control board to optimize superheat, subcooling, or space temperature setpoints. A failing 2228741 sensor often leads to compressor short-cycling or incorrect thermal expansion valve (TXV) adjustments, directly impacting system COP and energy efficiency.
Designed for demanding commercial HVACR applications, this assembly features a robust, moisture-resistant lead wire and a specialized probe housing that ensures rapid thermal response and long-term durability in high-vibration environments. Whether you are performing routine HVAC preventative maintenance or an emergency Daikin thermistor replacement, this genuine 2228741 thermistor provides the factory-calibrated reliability needed to prevent costly downtime. The 2228741 assembly is compatible with a wide range of Daikin-McQuay air handlers, rooftop units, and VRV systems, making it a staple for any technician's service van specialized in Daikin equipment.
Key Benefits- Precise Temperature Monitoring: Ensures exact temperature sensing for accurate system modulation and climate control.
- Direct OEM Compatibility: Engineered specifically for Daikin and McQuay equipment, eliminating the calibration drift seen with universal sensors.
- Enhanced System Resilience: Heavy-duty insulation and connectors prevent common failures caused by moisture ingress or terminal corrosion.
- Rapid Service Restoration: Pre-wired 2228741 sensor assembly allows for immediate plug-and-play installation during field repairs.
How do I check the resistance of a 2228741 thermistor?
Disconnect the sensor assembly from the PCB and use a calibrated multimeter to measure the resistance across the pins. Compare your readings against the standard Daikin thermistor resistance chart for the ambient temperature at the probe tip.
Will this part clear a Daikin C4 error code?
A C4 error typically indicates a fault with the liquid pipe thermistor for the indoor heat exchanger. If your diagnostics confirm the sensor is open, shorted, or out of spec, replacing it with a genuine 2228741 thermistor is the standard solution.
Does this thermistor assembly include the mounting clip?
The 2228741 includes the factory-attached connector and probe. We recommend inspecting the existing heat exchanger clip or thermistor well for damage before finalizing your service call.
