York S1-025-26392-003 Rollout Switch

The York S1-025-26392-003 Rollout Switch is a critical thermal safety component designed for precise combustion monitoring in York, Coleman, and Luxaire gas-fired furnaces. This SPST (Single Pole Single Throw) fixed-temperature limit is engineered to interrupt the burner circuit if it detects a flame rollout condition, preventing potential equipment damage or hazardous operation. Built by Therm-O-Disc, this flame rollout switch features a 145-degree F open temperature and a 105-degree F close temperature, allowing for an automatic reset once the burner vestibule cools to safe levels. Utilizing a 60TX11 style disc, this switch provides reliable circuit break logic in high-heat environments. For field technicians, this part is a direct replacement for York S1-02526392003 and York 025-26392-003, ensuring OEM-spec performance and terminal alignment during service calls.

• OEM Precision: Guaranteed compatibility with York HVAC systems, maintaining the original safety circuit integrity without field modifications.
• Automatic Reset Logic: Resets when temperatures drop to 105°F, reducing unnecessary system lockouts while ensuring the unit only operates under safe thermal conditions.
• Robust SPST Construction: Engineered for high-duty cycles in the burner compartment, providing a reliable electrical break at exactly 145 degrees F.
• Direct Cross-Reference: Replaces part number S1-025-26392-003 and equivalent 312980 and A1844 controls, streamlining inventory for service vans.

What causes the York S1-025-26392-003 to trip?
This switch typically opens due to a flame rollout condition caused by a clogged heat exchanger, incorrect manifold gas pressure, or restricted venting. If the switch trips, technicians should inspect the combustion path before resetting.

Can this rollout switch be used in other furnace brands?
While the 145F open/105F close specs are standard for many SPST rollout switches, this specific part is optimized for the mounting brackets and wiring harnesses found in York, Coleman, and Luxaire furnaces.

Is the S1-025-26392-003 a manual or automatic reset?
This is an automatic reset rollout switch. It will close the circuit once the temperature falls below the 105°F threshold, though recurring trips indicate a serious underlying combustion issue that requires professional diagnostic.
