The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor before allowing the ignition sequence to proceed. When the inducer motor runs and generates the correct pressure differential, the switch closes and signals the control board to advance through the ignition stages. A failed pressure switch will cause the furnace to lock out prior to ignition — often with a diagnostic fault code — leaving your home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HK06WC069 | Pressure Switch Assembly with Mounting Bracket | Single-stage draft-proving switch | Rated: -0.27\" W.C. break \/ -0.42\" W.C. max make\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is factory-calibrated to the exact water column rating required by the Carrier PG8JAA042090ABJA.
