Description
The York S1-024-23224-000 is an OEM-grade 370°F rollout switch designed to protect York furnaces from the hazards of flame rollout. When burner flames extend beyond their designated combustion area — due to a blocked heat exchanger, restricted flue, or inadequate combustion air — this safety switch detects the abnormal temperature rise and immediately interrupts the heating circuit, shutting down the burner before damage or injury can occur.
How It Works
The rollout switch is a thermal cutout device mounted near the burner assembly. Under normal operating conditions, the switch remains closed, allowing the furnace to run. If flame rollout causes temperatures at the switch location to reach the 370°F trip point, the switch opens the circuit and locks out the furnace, alerting the technician that further inspection is required before the system can be safely restored to operation.
Key Features
- OEM York replacement part — ensures proper fit and function
- 370°F trip temperature for precise, reliable flame rollout detection
- Manual-reset design requires technician inspection before system restart
- Protects heat exchanger, burner assembly, and surrounding components

Why Replace a Rollout Switch?
- A tripped rollout switch is a safety lockout — never bypass or jumper this device
- Repeated tripping indicates an underlying combustion or venting issue that must be diagnosed
- Replacing with the correct OEM part maintains system safety ratings and warranty compliance
