York S1-025-37419-000 Limit Switch allowing for efficient orifice resizingThe York S1 025 37419 000 Limit Switch is a critical OEM safety component designed for precise thermal regulation in York HVAC systems. As an L50 10F auto limit switch, this device operates on a fixed temperature differential, featuring a 50F opening temperature and a 40F closing temperature. This SPST (Single Pole Single Throw) control acts as a high limit watchdog, protecting the primary heat exchanger and blower assembly from overheating by
