The pressure switch is a critical safety component that monitors the inducer motor's vacuum pressure to confirm proper draft and safe flue gas venting before allowing ignition to proceed. When this switch fails or sticks open, the furnace control board will lock out the heating sequence — typically before the igniter ever fires — leaving you with a cold home and a blinking fault code. Common symptoms include the inducer motor running but the furnace never advancing to ignition, a pressure switch fault code on the control board, or repeated short-cycling with no heat output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e OEM part HK06NB021 (superseded by HK06MB021) | Honeywell cross-reference BA20268-2 | Dual-switch assembly with both switches included, each featuring 2 wire terminals and 1 hose port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM assembly, factory-matched to the exact water column (W.C.) rating required by the PG95XAT60100CBAA.
