York S1-025-28670-003 Limit Switch Built from high-strength alloy steel

Built from high-strength alloy steel with a corrosion-resistant coating

Reliable Safety Integration: Prevents furnace overheating and potential rollout issues by maintaining strict control over maximum operating temperatures

as long as the 460V primary and 24V secondary voltages remain the same

featuring the same standard 11/32-32 male nut connector that technicians expect for seamless integration

using OEM-spec control valve fasteners is essential to maintain structural integrity and prevent failure of the stem or linkage connections

York S1-025-28670-003 Limit Switch Built from high-strength alloy steelThe York S1 025 28670 003 Limit Switch is a critical safety component designed for precise thermal monitoring within York gas furnaces and residential air handlers. This automatic reset limit switch is engineered to operate within a specific 90 110F temperature range, ensuring the heat exchanger and plenum do not exceed safe operating parameters. When the sensed temperature hits the upper threshold, the internal bimetal disc opens the circuit to the
