York S1-025-35381-000 Limit Switch 000-hour operating lifeThe York S1 025 35381 000 Limit Switch is a critical HVAC safety control designed to monitor internal plenum temperatures and protect the heat exchanger from thermal stress. As a high limit auto reset switch, this component features a precise 145F opening temperature to interrupt the burner circuit upon detecting an overheat condition. Once the system cools to the 115F closing temperature, the switch automatically resets, allowing for the restoration
