York S1-025-41322-000 Limit Switch Bypassing a flame rollout switchThe York S1 025 41322 000 Limit Switch is a critical safety component designed for precise thermal monitoring within furnace and air handler heat exchangers. This OEM York furnace limit switch operates on an automatic reset logic with a calibrated temperature range of 120 160 degrees Fahrenheit. When the internal plenum temperature reaches the 160F high limit threshold, the bimetal disc triggers a circuit break to prevent heat exchanger fracturing or
