This 370/440 VAC dual run capacitor provides the necessary phase shift to support both the hermetic compressor (50 microfarads) and the condenser fan motor (5 microfarads)

Enhanced Flame Sensing: The high-output thermopile delivers a stable millivolt signal to prevent premature gas valve closure

Is the Lennox 49K03 compatible with R410A systems

Attempting to bore out the hub or force-fit it will compromise the balance and integrity of the assembly

Heat Controller R68CA0003 Limit Switch 340155-7024 This 370/440 VAC dual runThe 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
