York S1-025-35362-000 Limit

The York S1-025-35362-000 Limit is a critical safety component designed for precise thermal management in York, Coleman, and Luxaire gas furnaces. This high limit switch is engineered to open at 200°F, effectively cutting the burner circuit if the heat exchanger exceeds safe operating temperatures. Featuring a reliable auto-reset function, the circuit closes again once the ambient temperature drops to 170°F, allowing the system to resume normal cycling. For service technicians, utilizing genuine OEM York parts ensures the correct footprint and mounting configuration, preventing bypassed safety protocols or nuisance trips often seen with generic alternatives. This 200-degree limit switch is frequently diagnosed during lockout codes related to restricted airflow or failing blower motors. Integrating a replacement furnace limit switch with these exact setpoints is vital for maintaining the heat exchanger's structural integrity and ensuring safe combustion cycles in residential HVAC applications. Accurate temperature differentials are mandatory for efficient field troubleshooting and long-term system performance.

Key Benefits for Technicians:

• Direct OEM Replacement: Ensures exact fitment for York, Luxaire, and Coleman furnace models without bracket modification.
• Critical Temperature Control: Fixed 200°F opening point provides localized protection against heat exchanger overheating.
• Automatic Reset Logic: Returns to a closed state at 170°F, facilitating streamlined troubleshooting of intermittent thermal issues.
• Verified Calibration: Factory-tested setpoints eliminate the guesswork associated with universal aftermarket limits.

Common Technical Questions:

What typically causes a York S1-025-35362-000 to trip?
Trips are generally caused by restricted airflow across the heat exchanger. Technicians should inspect for clogged air filters, undersized ductwork, a dirty evaporator coil, or a failing blower motor capacitor.

Is the S1-025-35362-000 a manual or automatic reset?
This specific model is an automatic reset switch. It will automatically re-engage the burner circuit once the sensing element cools to 170°F.

Where is this limit switch usually located?
It is typically mounted on the furnace vestibule panel or the blower housing, where it can accurately monitor the internal air temperature passing over the heat exchanger.
