York S1-025-47244-000 Rollout Switch

For service technicians addressing flame rollout or secondary heat exchanger failure, the York S1-025-47244-000 Manual Reset Rollout Switch provides essential thermal protection within the burner compartment. This SPST (Single Pole Single Throw) safety control is a direct replacement for York S1-2940-3191, engineered to interrupt the 24V control circuit if it detects excessive rising heat indicative of a combustion breach or obstructed flue. As a manual reset device, it requires a physical inspection of the furnace cabinet before the burner can be relit, ensuring that underlying issues like a cracked heat exchanger or gas pressure imbalance are resolved by a professional contractor.

Designed for high-performance compatibility with York, Coleman, and Luxaire gas furnaces, this flame rollout limit switch maintains system integrity by preventing dangerous backdrafting. The compact housing and snap-action contacts facilitate a precise furnace limit control response. When replacing this component, ensure you verify the temperature rating on the existing switch to maintain the factory-specified safety parameters of the HVAC burner assembly.

• Precise Safety Trip: Provides reliable circuit interruption to prevent fire hazards during flame rollout events.
• OEM Compatibility: Specifically engineered as the S1-025-47244-000 replacement for the S1-2940-3191 to ensure exact fitment.
• Durable Construction: Features high-grade materials suited for the rigorous thermal environment of a gas furnace combustion chamber.
• Critical Diagnostic Tool: The manual reset requirement forces a necessary safety evaluation of the heat exchanger and venting system.

What causes a York furnace rollout switch to trip?
A trip is typically triggered by a blocked flue, cracked heat exchanger, or improper manifold gas pressure, all of which cause flames to "roll out" of the burner and toward the switch.

Can I bypass this switch for testing?
No. This is a critical safety component. If the switch trips, the technician must diagnose the root cause of the flame rollout before attempting to reset the control or operate the unit.

Is the S1-025-47244-000 compatible with older S1-2940-3191 models?
Yes, this part is the manufacturer-designated direct replacement for the S1-2940-3191 and will fit the existing mounting brackets and wiring harness.
