The Trane SWT1390 Limit Switch is a critical manual reset temperature control designed to protect HVAC systems from thermal overruns. Engineered for precise monitoring, this 160F CO M/R Limit Switch maintains circuit integrity by opening at a 160°F threshold, effectively preventing system damage due to localized overheating. As a veteran-preferred HVAC replacement part, it features a durable dual-pole configuration suitable for both heating and cooling equipment. Whether you are troubleshooting a rooftop unit or a furnace blower assembly, using this authentic Trane high limit switch ensures your repairs meet factory specifications for safety and air handler operational efficiency. This specific model, known by industry cross-references as SWT01390, provides the high-temp cutout reliability necessary for demanding industrial and commercial applications where automatic reset components are insufficient for safety protocols.

• Thermal Protection: Calibrated 160°F trip point ensures system-wide safety during high-temperature scenarios.
• Manual Reset Mechanism: Requires physical inspection after a trip, ensuring root causes are diagnosed before system restart.
• High-Level Compatibility: Direct replacement for several Trane and American Standard climate control platforms.
• Standardized Fit: Compact footprint allows for rapid installation within existing control panels and bracket assemblies.
• Fail-Safe Design: Engineered to provide a consistent open-circuit response when temperature limits are exceeded.

Is the Trane SWT1390 a direct replacement for SWT01390?
Yes, the SWT01390 is the current manufacturer part number, and the SWT1390 is recognized as the previous technical designation. They are functionally identical.

What does the "CO" designation signify for this limit switch?
In HVAC technical data, "CO" typically indicates a "Circulator" or "Cut-Out" function, specifically designed to interrupt the circuit to critical components like the gas valve or inducer motor.

Can this switch be used in cooling-only applications?
While primarily used for heat-limit protection, this switch is rated for both heating and cooling environments where a manual reset 160°F thermal safeguard is required.
