Trane CNT0674 v
The Trane CNT0674 is an industrial-grade 170-210F AUTO Limit Switch designed for high-performance temperature regulation in forced-air systems. As a SPST N/C (Single Pole Single Throw, Normally Closed) safety control, this component is critical for preventing heat exchanger overheating. The switch is calibrated to open at 210°F, effectively interrupting the burner or heating circuit when thermal limits are exceeded, and automatically resets when temperatures drop back to 170°F. This specific HVAC limit control replacement ensures system integrity and operational safety across various Trane air handler and furnace models. Engineered for reliability in high-temperature HVAC applications, the CNT0674 features a rugged design that withstands the cycling demands typical of commercial and residential heating environments. For professional contractors, installing this OEM Trane furnace part guarantees precise thermal response and compatibility, maintaining the factory-specified performance of the heating equipment without the risks associated with generic alternatives.
Key Benefits
- Factory-Calibrated Thermal Response: Precision 170-210°F range ensures HVAC high-limit protection is triggered exactly when needed.
- Automatic Reset Functionality: Minimizes downtime by restoring system operation once safe temperatures are achieved at the 170°F threshold.
- Direct OEM Compatibility: Specifically engineered for Trane HVAC systems, ensuring a perfect fit and standard wiring connection.
- Enhanced Equipment Safety: Acts as a primary fail-safe to protect heat exchangers from cracking due to excessive thermal stress.
Common Questions
What are the cut-out and cut-in temperatures for the CNT0674?
The Trane CNT0674 is designed to open (cut-out) the circuit at 210°F and automatically close (cut-in) once the temperature returns to 170°F.
How do I test the continuity of this limit switch?
Since this is a Normally Closed (N/C) switch, you should find continuity across the terminals at room temperature. If the switch shows an open circuit while cool, it has likely failed and requires replacement.
Is the Trane CNT0674 compatible with other brands?
While functionally similar to other 170-210F limit switches, it is primarily designed for Trane and American Standard equipment. Always verify original part numbers and thermal specs before substituting.
