The pressure switch proves that the inducer motor is operating correctly and generating sufficient negative pressure before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace will go into lockout immediately — typically before any ignition attempt — and the unit will display a pressure switch fault code. This listing covers both OEM part numbers \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch) and \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (Pressure Switch \/ High Fire), both factory-matched to this model.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e LP (Propane) Gas Pressure Switch | 6.5\" W.C. cutout rating | SPST configuration | Factory-authorized OEM replacement | Fits Carrier, Bryant, and Payne badge variants of this platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact W.C.
