York S1-024-23224-000 Rollout Switch

The York S1-024-23224-000 Rollout Switch is a critical safety component designed for high-limit thermal protection in residential and light commercial gas furnaces. This fixed temperature limit switch is calibrated to trip at 370°F, effectively breaking the 24V control circuit to the gas valve if it detects flame rollout or excessive heat buildup near the burner assembly. As a genuine OEM York replacement part, it ensures direct compatibility with Johnson Controls, Luxaire, and Coleman furnace platforms, maintaining the original equipment’s safety listing. This manual-reset switch is a primary defense against heat exchanger failure or flue blockages. Field technicians should verify the limit switch specifications and ensure the mounting bracket alignment matches the S1-024-23224-000 footprint for proper thermal sensing and system restoration.

Key Benefits for Technicians:

• Direct OEM Fitment: Eliminates mounting modifications in York and Coleman furnaces, ensuring the sensor sits correctly in the thermal airstream.
• Precision Calibrated Trip Point: Rated at 370 degrees Fahrenheit to prevent nuisance tripping while providing rapid response to flame rollout conditions.
• Manual Reset Mechanism: Requires a technician to inspect the heat exchanger and venting for underlying faults before the system can be restarted.
• Industrial Grade Construction: Built with high-temperature ceramics and bimetal discs to withstand the rigors of the burner compartment environment.
• Standardized Electrical Terminals: Features standard 1/4-inch spade connectors for quick integration into the existing safety string.

Common Questions:

What causes a 370°F rollout switch to trip?
A trip usually indicates flame rollout caused by a restricted flue, a cracked heat exchanger, or improper manifold gas pressure pushing heat back toward the burner manifold.

Can I bypass the S1-024-23224-000 for testing?
Bypassing a safety limit is never recommended. If the circuit is open, use a multimeter to check for continuity. If it shows high resistance or is open at room temperature, it must be replaced.

Is this switch compatible with other furnace brands?
While this is a York HVAC safety switch, it is also used across most Johnson Controls brands including Luxaire and Coleman. Always verify the part number against the unit’s specific data plate.
