York S1-025-26392-002 Rollout Switch

The York S1-025-26392-002 Rollout Switch is a critical safety component engineered for HVAC burner assemblies to monitor for flame rollout conditions. This SPST automatic reset switch is calibrated to open the electrical circuit at 160 degrees F, immediately interrupting the gas valve circuit if excessive heat is detected outside the combustion chamber. Once the environment cools to 120 degrees F, the switch resets automatically, allowing the furnace to resume its heating cycle. As a genuine OEM York replacement part, it ensures precise thermal response and mounting compatibility for various York, Coleman, and Luxaire gas furnaces. Technicians rely on this furnace flame rollout switch to replace failing safety sensors that cause nuisance trips or total system lockouts. Utilizing high-grade HVAC limit switch technology, this component maintains system integrity and protects the heat exchanger from damage. Professional installation of this furnace safety control is standard practice during preventative maintenance to ensure the sequence of operation remains within manufacturer specifications.

Key Benefits

• Automatic Reset Functionality: Minimizes system downtime by automatically closing the circuit once temperatures return to 120 degrees F.
• Precision Thermal Calibration: Ensures the York S1-025-26392-002 reacts accurately at its 160-degree threshold for optimal safety.
• OEM Compatibility: Constructed for direct fitment on York burner manifolds, reducing installation time for field contractors.
• Durable SPST Design: Single Pole Single Throw configuration provides a reliable point of failure for safety-critical circuits.

Common Questions

What causes a 160-degree rollout switch to trip?

A trip usually indicates a cracked heat exchanger, soot buildup, or improper venting that forces flames or hot flue gases out of the burner opening. Always inspect the heat exchanger for integrity when replacing safety switches.

Is the S1-025-26392-002 compatible with manual reset models?

This specific model is an automatic reset switch. You must verify the furnace nomenclature and wiring schematic to ensure an automatic reset is appropriate for the safety circuit being serviced.

How do I test the continuity of this switch?

With the power disconnected and the switch at room temperature, use a multimeter to check for continuity across the terminals. Since it is normally closed, you should see a near-zero resistance reading until the 160-degree limit is reached.
