The pressure switch is a critical safety device that proves the inducer motor is operating at the correct RPM and generating sufficient negative pressure (vacuum) before allowing the ignition sequence to proceed. When either switch in the dual assembly fails, the furnace control board will lock out the heating sequence entirely — leaving you with a blinking error code and no heat. Common failure symptoms include the inducer motor running but the furnace never advancing to ignition, a fault code indicating an open pressure switch, or the furnace cycling on and off repeatedly without firing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces OEM Part Numbers:\u003c\/strong\u003e HK06NB021 (Dual Pressure Switch Assembly) | HK02LB008 (Gas Pressure Switch) — both switches included in this dual assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part, factory-calibrated to the exact water column (W.C.) rating required by the PG92SAS60120DAAA. Aftermarket switches often use approximate W.C. ratings that can cause nuisance lockouts or, worse, allow the furnace to fire under unsafe venting conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Locate the pressure switch(es) on the inducer housing or manifold, label and disconnect the hose ports and wiring terminals, and swap the assembly.
