York S1-025-28670-003 Limit Switch it is fully compatible withThe York S1 025 28670 003 Limit Switch is a critical safety component designed for precise thermal monitoring within York gas furnaces and residential air handlers. This automatic reset limit switch is engineered to operate within a specific 90 110F temperature range, ensuring the heat exchanger and plenum do not exceed safe operating parameters. When the sensed temperature hits the upper threshold, the internal bimetal disc opens the circuit to the
