Lennox 11W51 Limit Switch 322838-752 Its compact design facilitates aThe Lennox 11W51 Limit Switch is a critical safety component designed for precise thermal regulation within high efficiency residential heating systems. Operating with a 160 190F temperature range, this auto reset limit switch is normally closed and engineered to open the circuit at 190F to prevent heat exchanger damage and potentially hazardous conditions. Once the plenum temperature cools back to 160F, the 11W51 automatically resets, allowing the
