The pressure switch is a critical safety component that monitors the negative pressure (vacuum) produced by the inducer motor before each heating cycle. If the inducer fails to reach the correct RPM — or if there is a blocked flue, cracked hose, or failed inducer — the pressure switch remains open, preventing the gas valve from firing and locking out the furnace. Common symptoms of a failed dual pressure switch include a furnace that attempts to start but shuts down before ignition, repeated error codes indicating a pressure switch fault, or a system that runs the inducer but never progresses to the ignition stage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual pressure switch assembly | Two independent switch circuits | Each switch features 2 wire terminals and 1 hose port | Factory-calibrated trip points matched to PG96VAT60100CBAA inducer performance | OEM part number HK06NB021 (current replacement: HK06MB021)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to the exact water-column (W.C.) opening and closing pressures required by your furnace's inducer. Aftermarket switches often carry wider tolerances, which can cause nuisance lockouts or, more dangerously, allow the furnace to fire under unsafe draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 3\/5\u003c\/strong\u003e — Turn off power and gas before beginning. Locate the pressure switch assembly on the inducer housing. Label and disconnect hose ports and wire terminals before removal. Inspect all rubber hoses for cracks or blockages — a collapsed hose is a frequent root cause of switch failure. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, manometer (recommended to verify draft pressure post-install).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
