York S1-024-35596-000 Limit Switch

The York S1-024-35596-000 is a critical OEM furnace limit switch designed to protect heating systems from thermal overload. As a veteran-grade HVAC safety control, this auto reset limit switch is engineered with a factory-calibrated 110F-150F operating range. The bimetal sensing element is tuned to open the electrical circuit at 150°F to prevent heat exchanger damage and close at 110°F once temperatures return to a safe operational threshold. This HVAC high limit replacement is essential for troubleshooting short-cycling issues or blower motor failures in York, Coleman, and Luxaire furnaces. Relying on an OEM York limit switch ensures proper fit and precise switch points, maintaining the manufacturer's safety specifications. For technicians, the universal mounting footprint of the S1-02435596000 allows for a rapid, direct-fit installation across various packaged units and air handlers.

• Precision Thermal Protection: Opens at 150°F and resets at 110°F to prevent furnace overheating.
• Automatic Reset Function: Restores system operation automatically without requiring manual intervention after a high-temperature trip.
• Broad Compatibility: Serving as a genuine Source1 part, it fits numerous York and Coleman furnace models, including EB and JCI series.
• Heavy-Duty Construction: Built with a heat-resistant housing and a highly accurate bimetal sensor for consistent performance in demanding environments.
• Safety Integrity: Prevents critical component failure and mitigates risks associated with blocked airflow or dirty filters.

When should a furnace limit switch be replaced?
If you notice the furnace is short-cycling or the blower fan runs continuously while the burner remains off, the limit switch likely has a failed bimetal element or a continuity break.

Is the S1-024-35596-000 an auto-reset or manual-reset switch?
This is an auto-reset limit switch, meaning it will automatically close the circuit once the plenum temperature drops back to 110°F.

Can I use a different temperature rating for my furnace?
It is critical to match the OEM specifications. Using a switch with a higher trip point can result in heat exchanger damage, while a lower trip point will cause unnecessary system shutdowns.
