York S1-025-26392-011 Rollout

The York S1-025-26392-011 Rollout Switch is a critical safety component designed for precise thermal monitoring in high-output burner compartments. This genuine OEM single pole single throw (SPST) temperature control is engineered to safeguard gas-fired furnaces, packaged units, and RTUs from hazardous flame rollout conditions. Functioning as a high-limit safety, the York furnace rollout switch is factory-calibrated with a 225°F open point to immediately break the heating circuit upon detecting excessive heat, and a 145°F close point for system reset. Its robust construction ensures consistent response times across repeated thermal cycles, maintaining the integrity of the heat exchanger and surrounding electronic controls.

For field technicians, the York S1-025-26392-011 offers a drop-in replacement for worn or tripped sensors in residential and light commercial air handlers. This HVAC rollout limit switch features standard spade terminals for rapid termination and a compact footprint for mounting in constrained burner vestibules. As a Source 1 HVAC part, it meets the rigorous metallurgy and tolerance standards required for Coleman, Evcon, and York equipment. Utilizing this specific 225 open 145 close rollout ensures the system remains compliant with original equipment manufacturer safety sequences, preventing premature component fatigue or nuisance tripping during normal operation.

• OEM Precision: Genuine York S1-025-26392-011 ensures exact 225°F trip and 145°F reset points for reliable safety logic.
• Universal Compatibility: Engineered for use in York, Coleman, and Evcon gas-fired heating equipment.
• Compact SPST Design: Simplifies wiring with a standard single-pole single-throw configuration for direct circuit integration.
• High-Temperature Durability: Built with premium thermal-sensing materials to withstand harsh burner environment conditions.
• Verified Performance: Rigorously tested to prevent flame rollout damage to the cabinet and internal controls.

What causes a rollout switch to trip at 225°F?
A trip at the 225°F threshold usually indicates a blocked heat exchanger, cracked heat exchanger, or improper drafting within the burner assembly that forces flames outward toward the sensor.

Is the S1-025-26392-011 an automatic or manual reset switch?
This specific model is designed as an automatic reset switch, meaning it will re-close the circuit once the ambient temperature at the sensor drops below 145°F.

Can I substitute this with a different temperature rating?
No. For safety and compliance, you should always replace a rollout switch with the exact temperature ratings (225°Open/145°Close) specified for the equipment's original safety string.
