The pressure switch monitors negative air pressure created by the inducer motor to confirm proper combustion airflow before the control board allows ignition to proceed. When either switch fails — due to a ruptured diaphragm, clogged port, or faulty hose connection — the furnace will lock out on a pressure switch fault code before the ignition sequence can begin, leaving you with no heat. Replacing it with the correct OEM part (HK06NB021) restores the precise trip-point calibration the factory control board expects.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual pressure switch assembly | OEM Part No. HK06NB021 | Factory-calibrated trip points for high-efficiency induced-draft operation | Designed for two-stage, 120,000 BTU input configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact water-column (W.C.) specifications for the PG95XAT66120DBAA.
