York S1-025-27747-013 Rollout Switch

The York S1-025-27747-013 Rollout Switch is a critical safety component designed for high-limit temperature monitoring in residential and commercial gas-fired furnaces. This manual reset rollout switch features a precise 270-degree Fahrenheit trip point, engineered to interrupt the heating cycle if a flame rollout condition or heat exchanger blockage occurs. Built with a single pole, single throw (SPST) circuit configuration, this OEM York furnace part ensures a normally closed circuit that opens under fault conditions to prevent equipment damage and hazardous venting. As a veteran-grade HVAC flame rollout limit, it provides reliable thermal protection for heat exchangers and burner assemblies. Technicians should verify the specific temperature rating against cabinet requirements to ensure proper safety sequencing. This genuine York 270F switch is a direct replacement for various York, Luxaire, and Coleman equipment, offering a secure fit and standard terminal connections for efficient field installation during emergency service calls or routine maintenance.

• Precision Thermal Trip: Factory-calibrated to 270°F for accurate detection of furnace flame rollout.
• Manual Reset Safety: Requires onsite technician intervention to reset the system, ensuring root cause diagnosis before operation resumes.
• SPST Configuration: Standard single-pole, single-throw electrical operation for seamless integration into existing 24V or 120V safety loops.
• OEM Standards: Genuine York replacement part ensures compatibility with original heat exchanger and burner specifications.

Can I replace this with an automatic reset switch?
No. For safety, rollout switches must be manual reset to ensure a professional inspection is performed following a trip condition.

What causes a 270-degree rollout switch to trip?
Common causes include a cracked heat exchanger, soot buildup in the secondary heat exchanger, or improper drafting within the flue system causing flames to roll out toward the cabinet.

Is the S1-025-27747-013 compatible with all York furnaces?
While used across many models, you must verify the specific temperature rating and mounting bracket style required by the unit's data plate.
