York S1-025-35358-000 150°F Manual Reset Limit Switch Overview
The York S1-025-35358-000 is a 150°F manual reset (M/R) high-limit switch engineered as a genuine OEM replacement for compatible York heating and HVAC systems. This safety device monitors supply-air or heat exchanger temperatures and opens the circuit when temperatures reach the 150°F threshold, shutting down the burner or heating element to prevent equipment damage and potential hazards. Because it features a manual reset design, the switch must be deliberately reset by a technician after a trip event — ensuring that the root cause of the overheat condition is identified and corrected before the system is returned to operation.

Why Manual Reset Matters
Unlike automatic-reset limit switches that cycle on and off repeatedly during an overheat condition, a manual reset limit switch locks out the system until a qualified technician physically resets it. This added layer of safety ensures that nuisance lockouts are investigated and resolved, protecting both the equipment and the occupants.
