Trane SWT1613 Limit Switch

The Trane SWT1613 Limit Switch is a critical safety component designed for precise thermal management in residential and commercial furnaces and air handlers. This 80-210F auto limit switch operates as an automatic reset thermal protector, preventing heat exchanger damage and hazardous conditions by interrupting the electrical circuit if internal plenum temperatures exceed safe operating limits. With a cut-out (open) temperature of 210°F and a cut-in (close) temperature of 180°F, this SPST furnace limit switch ensures consistent cycle control and equipment reliability.

Engineered for high-duty cycles, the Trane OEM replacement limit switch features quick connect terminals for rapid field integration and nickel-zinc plating for superior corrosion resistance and electrical conductivity. This 120V rated component is UL and CSA recognized, maintaining a small footprint with board-mount versatility. Whether you are performing a Trane furnace repair or a routine system overhaul, using this HVAC high limit switch maintains the original engineering specifications for safety and performance.

• Automatic Reset Operation: Eliminates service calls for manual resets by restoring function once temperatures stabilize to 180°F.
• OEM Precision: Guaranteed Trane HVAC part compatibility for models such as the TUX, TDX, and AUX series furnaces.
• Heavy-Duty Contacts: Rated for up to 5.8A (FLA) at 120V with a high locked rotor current capacity.
• Durability: Rugged construction designed to withstand the high-temperature environment of an active heat exchanger.

• What causes a limit switch to open? Typically, restricted airflow from dirty filters, a failing blower motor, or blocked ductwork causes the plenum temperature to reach the 210°F high limit trip point.
• Can this switch be used in 24V circuits? While rated for 120V applications, this SPST thermal switch is commonly utilized in low-voltage control loops to signal the control board of an overheat condition.
• How do I verify compatibility? Contractors should cross-reference the Trane SWT1613 Part Number with the specific furnace model number on the rating plate to ensure proper temperature range matching.
