Reznor 271994 Sensor
The Reznor 271994 Averaging Temperature Sensor is a critical OEM replacement part engineered for precise thermal feedback in mixed air and cooling coil applications. Featuring a 36-inch length, this YD B type sensor is designed to mitigate the effects of stratified airflow by measuring the temperature across a wider cross-section of the duct. This ensures the HVAC controller receives an accurate average reading rather than a localized "hot" or "cold" spot, which is essential for maintaining proper discharge air temperature control and system efficiency. As a factory-authorized Reznor part, it provides direct mechanical and electrical compatibility with existing Reznor commercial units, reducing troubleshooting time and preventing short cycling or evaporator coil icing caused by inaccurate sensor data. For technicians servicing complex air handling configurations, this thermistor-based sensor is necessary for stabilizing the economizer and cooling stages.
Technical Benefits for Professionals:
- 36-Inch Averaging Length: Eliminates false readings from air stratification in large return or mixed air plenums.
- Optimized for Mixed Air: Provides the high-resolution feedback needed for economizer control and ASHRAE 90.1 compliance.
- Direct OEM Fitment: Ensures the resistance curve matches the system controller specifications for immediate calibration.
- Industrial-Grade Build: Designed for continuous exposure to high-velocity airflow and fluctuating humidity within the cooling coil assembly.
Common Service Questions:
How do I test the Reznor 271994 if I suspect drift?
Technicians should measure the DC resistance across the sensor leads and compare the value to the standard Reznor thermistor resistance chart for the ambient temperature present at the duct.
Can this be used for both heating and cooling applications?
Yes, while frequently utilized as a mixed air sensor or cooling coil freeze stat, it is rated for the full operational range required by Reznor air handlers and unit heaters.
Is mounting hardware included with this part number?
This part number typically includes the 36" sensor element; ensure existing mounting clips or brackets are intact during the field replacement process.
This item is not eligible for free shipping.
