Precision Thermal Trip: Calibrated to trigger at 200 degrees Fahrenheit

York S1-025-28670-002 Limit Switch Els PW 17895 making it easier to monitorThe York S1 025 28670 002 Limit Switch is a critical safety component designed for precise thermal monitoring within residential gas furnaces and air handlers. This high limit control features fixed set points, engineered to break the electrical circuit to the gas valve if the heat exchanger temperature reaches the 120 degree opening temperature threshold. Once the plenum cools to the 80 degree closing temperature, the switch automatically resets,
