Description
The York S1-025-26392-012 is an OEM rollout switch engineered to protect furnaces and heating systems from dangerous burner flame rollout conditions. Designed as a direct replacement for compatible York equipment, this automatic-reset SPST switch provides reliable, repeatable thermal protection without requiring manual intervention after the system returns to safe operating temperatures.
How It Works
The rollout switch continuously monitors burner compartment temperatures. If flame rollout or excessive heat is detected, the switch opens its circuit at 160°F, shutting down the burner to prevent heat exchanger damage, component failure, or fire hazard. Once temperatures fall back to a safe level — 120°F — the switch automatically resets and restores normal furnace operation.
Key Features
- Opens (trips) at 160°F to interrupt burner operation during rollout events
- Automatically resets (closes) at 120°F — no manual reset required
- SPST (Single Pole, Single Throw) configuration for straightforward wiring integration
- Automatic reset design reduces service call frequency after nuisance trips
- OEM York replacement part — engineered for precise fit and function
- Protects heat exchangers, wiring, and surrounding components from rollout damage
Application
This rollout switch is intended for use in York furnaces and compatible heating equipment as a direct OEM replacement. Always verify compatibility with your specific unit model before installation. Proper installation by a qualified HVAC technician is recommended.
