York S1-025-26392-005 Rollout Switch

When you're out on a service call for a York unit and the burners are cutting out prematurely, you need a reliable flame rollout switch that integrates seamlessly with existing safety circuits. The York S1-025-26392-005 Rollout Switch is a critical SPST (Single Pole Single Throw) limit control designed for furnace applications where thermal protection is non-negotiable. This specific automatic reset furnace switch is calibrated to open at 225 degrees F to arrest ignition sequences during a rollout event and will automatically close once temperatures settle back to 145 degrees F, ensuring the system can return to normal operation without a manual reset after the transient heat issue is resolved.

This genuine OEM York part is the primary replacement for technicians servicing residential and light commercial equipment. Whether you are troubleshooting a furnace rollout switch replacement or confirming continuity on a suspect York limit control, this component ensures the control board receives precise signals. Its SPST contact configuration and standard mounting footprint make it a direct swap-out for York S1-025-26392-005, maintaining the original engineering specifications for safety and performance in the field.

• Precision Thermal Calibration: Engineered with a fixed 225°F open and 145°F close setpoint for consistent safety response.
• Automatic Reset Logic: Eliminates unnecessary downtime by resetting itself once the burner compartment cools to safe levels.
• OEM Compatibility: Designed specifically for York HVAC systems to meet exact furnace safety switch electrical loads.
• Efficient Troubleshooting: Durable SPST contacts allow for quick continuity testing during routine preventative maintenance.

Is the S1-025-26392-005 a manual or automatic reset switch?
This model is a dedicated automatic reset switch. It will restore the circuit once the temperature drops to the 145°F threshold, unlike manual reset versions that require a technician to physically press a button.

What causes a York rollout switch to trip at 225°F?
Typically, this switch opens due to insufficient draft in the heat exchanger, a cracked heat exchanger, or a blocked flue, causing flames to "roll out" toward the burners instead of being pulled through the assembly.

Can I use this as a universal limit control?
While it serves as a SPST rollout switch, it is highly recommended to only use this as a direct replacement for the York S1-025-26392-005 to ensure the temperature setpoints and reset logic match the manufacturer's safety sequence.
