York S1-025-29759-001 Limit Switch

Maintain the operational integrity of your heating equipment with the York S1-025-29759-001 Limit Switch. This high-reliability Source 1 OEM replacement part is engineered for precision thermal monitoring in York, Coleman, and Luxaire furnaces. Operating as a critical safety component, this auto-reset limit switch features a specialized 100-160°F temperature range, ensuring the system interrupts the burner circuit if internal heat exceeds safe parameters. As a veteran-grade HVAC high-limit supervisor, it eliminates the downtime associated with manual resets while providing an exact 3-inch insertion depth for proper mounting in the heat exchanger airflow. Replacing legacy part number 025-29759-001 and cross-referenced with 208W05, this component ensures your gas-fired heating units maintain rigorous manufacturer specifications for safety and sequencing. Field-tested for heavy-duty cycling, its L160-30F rating ensures the burner cuts out at peak temp and resumes operation once the plenum has cooled, protecting the primary heat exchanger from stress fractures and overheating.

• OEM Compatibility: Exact fit for York, Coleman, and Luxaire gas furnaces, ensuring no modification is required during installation.
• Automatic Reset: Features a 100-160°F range with an automatic reset function (L160-30F), reducing nuisance service calls.
• Safety Compliance: Acts as a primary safety mechanism to prevent heat exchanger damage and hazardous operating conditions.
• Standardized Fit: 3-inch probe length designed for universal mounting in standard York residential furnace cabinets.

• What are the open and close temperatures? This switch is designed to trip (open) at 160°F and automatically reset (close) once the temperature drops by 30°F, typically around 130°F.
• Will this work for other brands? While sourced by York (Source 1), it is compatible with many Coleman and Luxaire units that utilize part S1-025-29759-001 or 025-29759-001.
• Does this require a manual reset? No, this is an auto-reset model. If your unit is constantly tripping, investigate airflow issues like a clogged filter or a failing blower motor.
