York S1-025-27747-017 Rollout Switch
The York S1-025-27747-017 Rollout Switch is a critical OEM replacement part designed for high-limit temperature monitoring in York, Coleman, and Luxaire gas furnaces. This rollout switch is precision-calibrated to trip at 350°F, effectively breaking the 24V safety circuit to the gas valve if flame rollout or heat exchanger compromise occurs. As a manual reset rollout switch, it requires a physical inspection of the combustion area by a technician before the system can be restored to operation, preventing repeated cycling under hazardous conditions. Built to OEM specifications, the S1-025-27747-017 features a standard SPST (Single Pole Single Throw) configuration and two spade terminals for rapid, secure integration into the existing wiring harness. Its robust construction resists thermal fatigue, ensuring stable set-point accuracy across thousands of heating cycles in residential and commercial furnaces.
Key Benefits for Technicians:
- OEM Compatibility: Direct substitute for factory-installed rollout limiters in York and Johnson Controls equipment, ensuring exact fitment with original mounting holes.
- Precise 350°F Trip Point: Engineered for rapid thermal response to protect heat exchangers and internal components from catastrophic heat damage.
- Manual Reset Safety: Hard-trip mechanism ensures the cause of the rollout is diagnosed and resolved before the burner can re-ignite.
- Durable SPST Contacts: High-reliability mechanical contacts designed to handle standard 24VAC safety loops without voltage drop.
- Quick-Connect Terminals: Equipped with industry-standard 1/4" spade connectors for efficient field replacement during service calls.
Common Questions:
Can I replace a 350°F rollout switch with a lower temperature model?
No. Using a switch with a lower temperature rating will result in "nuisance tripping," where the furnace shuts down during normal operation. Always match the S1-025-27747-017 temperature specification of 350 degrees F to maintain the engineered safety profile of the unit.
Why is the rollout switch tripping on my York furnace?
A tripped manual reset rollout switch typically indicates a restriction in the heat exchanger, a blocked flue, or excessive gas pressure. These conditions cause flames to "roll out" of the burner assembly toward the switch. The York S1-025-27747-017 is doing its job by disabling the gas valve to prevent a fire hazard.
Is the S1-025-27747-017 compatible with Coleman furnaces?
Yes. Because York, Coleman, and Luxaire are all brands under the Johnson Controls umbrella, this OEM rollout switch cross-references across multiple furnace models from these manufacturers.
