York S1-373-01911-605 Limit Switch

The York S1-373-01911-605 is a high-precision, OEM replacement limit switch engineered for critical temperature regulation in heavy-duty HVAC systems. This 130-195F auto limit switch serves as a vital safety component, specifically designed for use with York model D2CG180N24046C. Featuring a robust steel housing, this bimetal limit control is built to withstand the rigorous cycling of commercial and industrial heating environments. The auto-reset functionality ensures that once the high-limit threshold of 195°F is reached and the system cools back to 130°F, the switch automatically restores the circuit, reducing unnecessary downtime and manual intervention for service technicians. This furnace high limit switch (cross-reference 208W32) provides the reliable thermal protection required to prevent heat exchanger damage and maintain optimal airflow safety across various York HVAC units. Its factory-calibrated settings ensure precise HVAC temperature control without the risk of drifting, making it a drop-in solution for field repairs.

• OEM Precision: Guaranteed compatibility with York D2CG180N24046C units for seamless field integration.
• Automatic Recovery: The auto-reset feature eliminates the need for manual resets after temporary high-limit conditions.
• Durable Construction: Heavy-duty steel housing protects internel bimetal components from mechanical stress in the plenum.
• Wide Operating Range: Maintains system safety with a fixed differential between the 195°F open and 130°F close points.

Is the York S1-373-01911-605 a manual or auto reset switch?
This is an auto-reset limit switch, meaning it will automatically close back to its normal state once the temperature drops to 130°F.

Which HVAC models are compatible with this limit control?
It is primarily designed for York units, specifically model D2CG180N24046C. Always verify the part number on your existing component.

What happens if the furnace exceeds 195°F?
The S1-373-01911-605 will trip and open the circuit to shut down the heating source, protecting the heat exchanger from overheating.
