Description
York S1-025-47244-000 Manual Reset SPST Rollout Switch
The York S1-025-47244-000 is an OEM manual reset (M/R) single-pole, single-throw (SPST) rollout switch designed to protect York furnaces from dangerous flame rollout conditions. When the burner flame rolls out beyond its normal boundary — due to a blocked heat exchanger, restricted flue, or insufficient combustion air — this safety switch trips and shuts down the burner circuit, preventing potential fire hazards and equipment damage.
Key Features
- Manual reset (M/R) operation — requires deliberate technician reset after trip, ensuring the root cause is identified before resuming operation
- SPST (single-pole, single-throw) circuit configuration for reliable, straightforward burner shutoff
- OEM York replacement part — engineered to exact factory specifications for direct fit and dependable performance
- Acts as a critical safety device, detecting abnormal flame rollout and interrupting the burner circuit immediately
- Durable construction suited for the thermal demands of residential and light-commercial furnace applications
Application
- Designed as a direct OEM replacement for compatible York furnace models
- Mounts in the burner compartment to monitor flame position during normal operation
- Works in conjunction with the furnace control board to provide multi-layer safety protection
Why Manual Reset?
Unlike automatic-reset switches, a manual reset rollout switch requires a technician to physically reset the device after it trips. This design intentionally prevents the furnace from restarting until a qualified service professional has inspected and corrected the underlying cause — such as a cracked heat exchanger, blocked flue, or combustion air deficiency — making it an essential safety component in any furnace system.
