The pressure switch is a critical safety component that proves the draft inducer motor is running at the correct speed and generating sufficient negative pressure before allowing the ignition sequence to proceed. When this switch fails — or its sensing hose cracks — the furnace control board will lock out on a pressure switch fault, typically flashing a fault code before a single ignition attempt is ever made. Common symptoms include the inducer motor spinning normally but the furnace never advancing to ignition, or a repeated 3- or 4-flash error code on the IFC board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK02LB008 (Gas\/LP Pressure Switch) | HK06WC091 (Pressure Switch, High Fire) — both covered by this listing for the PG8MAA060090AFJA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Factory OEM switches are calibrated to the exact water column (W.C.) set-point for this furnace.
