The Trane KIT13630 Inducer Limit Switch Kit is a critical safety component designed to monitor and regulate the temperature of the draft inducer motor assembly. As the direct engineering replacement for the Trane SWT1712, this kit ensures the furnace shuts down if temperatures exceed safe operating parameters, preventing component damage and potential safety hazards. This OEM-spec HVAC high limit switch is built for precision, featuring a primary opening threshold of 155 ± 5°F and a reset (close) point of 95 ± 10°F. The 9-inch lead length allows for proper positioning within the vestibule, ensuring accurate thermal sensing and reliable communication with the Integrated Furnace Control (IFC). Replacing a faulty furnace limit switch with the KIT13630 prevents nuisance tripping and system lockouts caused by thermal overload. This Trane replacement part is rated for 5.8 FLA and 34.8 LRA at 120 VAC, making it compatible with various American Standard and Trane furnace configurations, particularly those in downflow vertical applications where heat stratification is common. The kit includes the switch, a new gasket, wire harness, and mounting screws to ensure a complete, airtight seal to the heat exchanger vestibule panel. Key Benefits Ensures accurate 155-degree thermal cutoff for draft inducer motor protection. Direct replacement for SWT1712 and SWT01712 ensures perfect fitment and electrical compatibility. Integrated secondary reverse flow protection helps prevent overheating in downflow HVAC installations. Comprehensive kit including inducer limit switch gasket and harness simplifies field replacement for technicians. Heavy-duty 120/24 VAC rating supports standard furnace control circuit requirements. Common Questions Is the KIT13630 compatible with my vertical downflow furnace? Yes, this kit is specifically engineered to mitigate nuisance tripping in vertical downflow applications by positioning the thermal sensor for optimal response to heat exchanger conditions. What are the specific electrical ratings for this limit switch? The Trane KIT13630 is rated for 5.8 Full Load Amps (FLA) and 34.8 Locked Rotor Amps (LRA) at 120 VAC, with a minimum 200 mA rating for 24 VAC systems. Does this kit include the necessary hardware for installation? Yes, the kit comes complete with the limit switch, a secondary wire harness, gasket, and the required mounting screws for a professional-grade installation.
