York S1-025-26392-010 Rollout Switch

The York S1-025-26392-010 Rollout Switch is a critical safety component designed for heat exchanger monitoring in gas-fired heating systems. This SPST furnace rollout switch is engineered to interrupt the burner circuit when it detects excessive temperatures caused by poor drafting or flame rollout conditions. Rated with a 145 degree F open temperature and a 105 degree F reset temperature, this switch provides precise thermal protection. Unlike manual reset models, this automatic reset limit switch restores the circuit once temperatures return to the safe operating range, making it ideal for York HVAC furnace parts replacement. For technicians troubleshooting combustion issues, this OEM York part ensures the system remains within factory-specified safety parameters. Its SPST (Single Pole Single Throw) configuration allows for seamless integration into standard 24V control loops. When installing, ensure the mounting surface is clean to maintain accurate thermal conductivity and prevent nuisance tripping in high-heat environments.

Key Benefits

• Precision Thermal Response: Calibrated for a strict 145 degree F open threshold to protect the burner vestibule from thermal damage.
• Automated Recovery: Features an automatic reset at 105 degrees F, ensuring system continuity once the overheating condition is resolved.
• OEM Compatibility: Designed as a direct replacement for York S1-025-26392-010, ensuring the correct footprint and electrical rating for residential units.

Common Questions

What causes a rollout switch to trip? A trip is usually triggered by a cracked heat exchanger, a blocked flue, or insufficient combustion air. If this rollout switch opens, technicians should inspect the venting and heat exchanger integrity immediately.

Is this switch compatible with other furnace brands? While the SPST configuration and 145-degree rating are common, this part is specifically validated for York, Luxaire, and Coleman equipment. Always verify your specific model number against the factory parts list.

Does this require manual intervention after a trip? No, this is an automatic reset switch. It will close the circuit once the sensor cools to 105 degrees F, though the underlying cause of the trip must still be addressed by a professional.
