York S1-025-28670-002 Limit Switch Els PW 17895 Rugged 8-inch rigid probe constructed

Rugged 8-inch rigid probe constructed from 304 stainless steel resists corrosion and physical stress

deep pitting or hairline cracks in the porcelain require a full replacement of the Lennox 83L71 to ensure long-term system reliability

Precision Thermal Trip: Calibrated to trigger at 200 degrees Fahrenheit

whereas P-series probes often feature PTFE coating for specific insulating requirements

York S1-025-28670-002 Limit Switch Els PW 17895 Rugged 8-inch rigid probe constructedThe 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,
