Heat Controller R68CA0003 Limit Switch 320735-701 ensuring reliable combustion safety whereThe Heat Controller R68CA0003 Limit Switch is a critical HVAC safety control designed to prevent heat exchanger damage in gas fired furnaces and air handlers. This L170 40F limit switch features a 170? F trip point, automatically breaking the electrical circuit if internal plenum temperatures exceed safety thresholds to prevent overheating. Once the system cools to 40? F, the auto reset limit switch restores continuity, allowing the heating cycle to
