The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. Once the correct W.C. (water column) threshold is confirmed, the switch closes and signals the control board to proceed with ignition. When this switch fails — or the diaphragm cracks — the furnace will lock out before ever reaching the ignition stage, leaving you with a cold call and a blinking fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC091 | Factory-rated W.C. setpoint | SPST normally-open | Direct fit for Carrier PG8JAA036110AAJA packaged gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact W.C. tolerances from the factory.
