The pressure switch is a critical safety component that monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When this switch fails or sticks open, the control board cannot verify safe draft conditions — resulting in a no-heat lockout, a blinking fault code, or a furnace that runs the inducer but never advances to ignition. Replacing it with the correct OEM part ensures exact pressure rating compliance and reliable operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC090 | Includes factory mounting bracket | Rated to exact W.C.
