The pressure switch is a critical safety device that proves the inducer motor is operating and creating adequate negative pressure before allowing the ignition sequence to proceed. When one of these switches fails — or its tubing collapses, clogs, or cracks — the control board interprets it as an unsafe condition and locks out the furnace, resulting in a no-heat call with a pressure switch fault code. Replacing the correct switch (or the full kit) restores normal operation quickly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded OEM Part Numbers:\u003c\/strong\u003e \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch) | \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (Pressure Switch) | \u003cstrong\u003eHK06WC100\u003c\/strong\u003e (Pressure Switch w\/ Bracket) — all three are factory-matched for the PG8MAA036045AGJA and cover all switch positions on the inducer assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier pressure switches are calibrated to exact water-column (W.C.) trip points specified for this unit's heat exchanger and inducer combination.
