York S1-025-32650-000 Temperature Control

The York S1-025-32650-000 is an OEM replacement temperature control designed specifically for precision thermal management in residential and light commercial forced-air systems. Engineered to maintain rigorous safety standards, this high-limit switch features a preset 280-degree Fahrenheit opening setpoint and a 250-degree Fahrenheit closing threshold. As a critical component for York equipment troubleshooting, it prevents heat exchanger damage by interrupting the burner circuit when internal temperatures exceed safe operating parameters. This 3-inch furnace limit switch is built for high-cycle reliability and serves as a direct replacement for various Source1 HVAC parts used across York, Coleman, and Luxaire platforms. Field technicians rely on this L280F-30 limit switch for its consistent SPST (Single Pole Single Throw) snap-action performance, ensuring that the system returns to normal operation only after a safe 30-degree temperature drop is achieved. Replacing a tripped or resistive limit switch with this genuine part maintains the original equipment integrity and calibration of the furnace's safety string.

• OEM Precision: Guaranteed compatibility with York furnace replacement parts, eliminating the calibration risks associated with universal aftermarket components.
• Thermal Safety: Provides essential protection against overheating caused by restricted airflow, dirty filters, or blower motor failure.
• Snap-Action Reliability: Features a fixed 280-degree open and 250-degree close cycle (30°F differential) for consistent system response.
• Simplified Installation: Standard 3-inch mounting profile fits existing York, Coleman, and Luxaire furnace cabinets without modification.

Is the York S1-025-32650-000 a manual or automatic reset switch?
This is an automatic reset limit switch. Once the temperature drops to the 250-degree Fahrenheit closing point, the internal contacts will automatically reconnect to allow for regular operation.

What causes this limit switch to trip frequently?
Frequent tripping usually indicates an airflow restriction. Technicians should inspect for a clogged air filter, blocked return grilles, or a failing indoor blower motor that is not moving enough air across the heat exchanger.

Can I use this switch in a Coleman or Luxaire unit?
Yes, as an official Source1 component, the York S1-025-32650-000 is the correct OEM replacement for many Coleman temperature control and Luxaire high-limit applications that require a 280-degree cutout.
