The pressure switch monitors negative pressure produced by the inducer motor to confirm proper draft before allowing the ignition sequence to proceed. When it fails — or when tubing cracks and leaks — the furnace control board detects an open switch circuit and locks out the heat call, leaving you with a cold house and a blinking fault code. Common symptoms include no heat, inducer runs but furnace never lights, or a pressure-switch fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK06NB020 (Dual Pressure Switch Assembly) | HK02LB008 (Gas Pressure Switch) — both cross-reference to this assembly for the PG92SBS30040AAAA platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to exact W.C. (inches water column) ratings. Off-brand switches frequently drift outside tolerance, causing nuisance lockouts or, worse, allowing ignition under unsafe draft conditions. Always use OEM on 90%+ efficiency condensing furnaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 3\/5\u003c\/strong\u003e — Requires shutting off gas and power before servicing.
