Description
The York S1-025-26392-010 is a factory-specified rollout switch engineered to protect your furnace from dangerous flame rollout conditions. Designed as a direct OEM replacement for compatible York heating systems, this switch provides dependable thermal cutout performance and automatic reset capability, keeping your equipment safe and operational.
How It Works
This SPST (Single-Pole, Single-Throw) rollout switch continuously monitors burner compartment temperatures. When abnormal heat from flame rollout is detected, the switch opens the circuit at 145°F, shutting down the burner to prevent heat exchanger damage, fire hazards, and carbon monoxide risks. Once temperatures return to a safe level, the switch automatically resets at 105°F — restoring normal operation without requiring manual intervention.

Why Rollout Switch Replacement Matters
A faulty or tripped rollout switch that won’t reset is a sign of an underlying combustion or venting issue. Replacing a failed switch with a genuine York OEM part ensures your safety circuit performs exactly as designed — protecting your equipment, your customers, and your reputation.
