York S1-025-27792-009 Rollout Switch

The York S1-025-27792-009 is a critical safety component designed for precise thermal monitoring in high-efficiency gas furnaces. Rated for a 350 degree F open temperature, this rollout switch replacement monitors the burner vestibule for excessive heat caused by compromised heat exchangers or flue blockages. As a manual reset limit, it necessitates a physical inspection of the combustion area before the system can be restored to operation, preventing hazardous repetitive cycling in the event of flame rollout. This gas furnace safety control serves as a direct OEM component for York, Luxaire, and Coleman units, ensuring internal safety protocols meet original equipment standards. For field technicians, installing this flame rollout sensor is a standard procedure when addressing safety circuit faults, ensuring the burner assembly is deactivated if temperatures exceed the safe operational threshold due to restricted airflow or venting backdraft.

• Provides a critical thermal safety cutoff at 350 degrees Fahrenheit.
• Integrated manual reset requires diagnostic verification before system restart.
• Direct OEM replacement ensures proper fitment and terminal alignment.
• Designed for high-heat environments common in modern gas furnace vestibules.

Frequently Asked Questions

Why is my York rollout switch tripping?
Trip events typically indicate a failure in combustion airflow, such as a cracked heat exchanger or a blocked vent pipe. The 350 degree F manual reset limit triggers when flames "roll out" toward the burner front rather than being drawn through the heat exchanger.

Can I reset the S1-025-27792-009 and continue operation?
While the switch can be manually reset, the underlying cause of the thermal trip must be identified first. Operating a furnace with a recurring rollout trip is a high-risk scenario that requires a full inspection of the heat exchanger and venting system.

Is this switch compatible with Coleman or Luxaire furnaces?
Yes, the York S1-025-27792-009 is the standard flame rollout sensor for most equipment manufactured under the Johnson Controls HVAC umbrella, including Coleman and Luxaire brands, provided the temperature rating matches the original specification.
