This switch senses the pressure differential created by the inducer blower and signals the control board when adequate airflow is confirmed, allowing ignition to proceed. It is a safety-critical component in the burner proving sequence. Licensed HVAC technicians and heating equipment service professionals handle installation and replacement of this switch during routine maintenance or fault diagnosis.\u003c\/p\u003e\u003cp\u003eThe L100166230 is suited for use in residential and light commercial gas-fired heating applications where combustion air proving is required. It serves as an OEM-style replacement for existing air pressure switches in LOCHINVAR heating equipment. When diagnosing inducer or pressure switch fault codes, technicians typically verify the switch operation before replacing it.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMonitors combustion air differential pressure to confirm inducer blower operation\u003c\/li\u003e\n\u003cli\u003eSafety interlock function prevents ignition without confirmed airflow\u003c\/li\u003e\n\u003cli\u003eOEM replacement part sourced directly from LOCHINVAR\u003c\/li\u003e\n\u003cli\u003eDesigned for integration with standard furnace or boiler control board circuits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement air pressure switch for LOCHINVAR gas-fired heating equipment.
