Lennox 63W57 (101021-12) - 2-Stage Pressure Switch
Set Point High: 0.95" W.C. | Set Point Low: 0.55" W.C.
The Lennox 63W57 (101021-12) is a factory-original 2-stage pressure switch engineered to support high-efficiency, multi-stage gas furnaces. This pressure switch monitors and regulates combustion airflow by verifying that the inducer motor creates proper draft pressure before ignition and throughout the heating cycle.
 
Key Features:
  • Dual-Stage Functionality: Specifically designed for 2-stage gas furnaces, the switch includes two pressure set points to correspond with low- and high-fire operations.
  • Set Points:
    • Low Stage Activation: 0.55 inches Water Column (W.C.)
    • High Stage Activation: 0.95 inches W.C.
  • OEM Part: Genuine Lennox part for exact fit, function, and reliability.
  • Application: Used in select Lennox furnaces to ensure safe startup and operation by preventing ignition when venting or pressure conditions are inadequate.
  • Part Numbers:
    • Lennox Catalog #: 63W57
    • Manufacturer #: 101021-12
  • Mounting: Bracket included; attaches inside the furnace cabinet with hose ports for easy integration into existing tubing systems.
  • Safety Role: Automatically interrupts furnace ignition if correct pressure levels are not met, helping to protect against unsafe operating conditions.
Compatibility:
Fits a variety of Lennox models using dual-stage heat control. Always verify with the unit’s model and serial number or consult your HVAC technician to ensure compatibility.
