York S1-025-47176-000 Limit Switch
The York S1-025-47176-000 Limit Switch is a critical safety component designed for precise thermal monitoring in HVAC furnaces and residential heating systems. Engineering specifications for this OEM York part include a fixed 130°F trip point (open) and a 95°F reset point (close). This high-limit control prevents heat exchanger damage by interrupting the burner circuit when internal temperatures exceed safe operating parameters due to restricted airflow or blower failure. As a standard furnace limit switch replacement, this component ensures the system remains within its design temperature rise. The S1-025-47176-000 is built for rapid thermal response and high-cycle reliability in demanding heating cycles, making it a staple for contractors maintaining York, Luxaire, and Coleman equipment. Heavy-duty construction facilitates a direct-fit installation, restoring the factory safety sequence and protecting the furnace heat exchanger from catastrophic thermal stress. Maintaining this 130/95 limit switch is essential for preventing short-cycling and ensuring long-term system integrity.
Key Benefits:- Precise Thermal Calibration: Features a factory-set 130 degree open and 95 degree close threshold to maintain strict safety tolerances.
- Direct OEM Replacement: Guaranteed compatibility with York S1-025-47176-000 specifications, eliminating the need for field modifications.
- System Protection: Acts as a primary safety sentinel to prevent overheating caused by clogged filters or failing inducer motors.
- Enhanced Reliability: Professional-grade internal contacts designed to handle the inductive loads of modern furnace control boards.
What causes a York high limit switch to trip repeatedly?
Repeated trips are usually caused by airflow restrictions, such as a clogged air filter, blocked return ducts, or a failing blower motor. Always check static pressure and filter condition before assuming the switch itself has failed.
Is this switch an automatic or manual reset?
The S1-025-47176-000 is an automatic reset limit switch. It will automatically close the circuit once the heat exchanger cools down to the 95°F reset point, allowing the furnace to attempt a new ignition cycle.
How do I test the continuity of this limit switch?
With power disconnected and the system cool, use a multimeter to check for continuity across the two terminals. Since this is a normally closed (NC) switch, you should read near zero ohms. If the circuit is open at room temperature, the switch is faulty and requires replacement.
