The pressure switch is a critical safety component that monitors the negative pressure (inches of water column) created by the inducer draft motor before allowing the ignition sequence to proceed. If the switch fails to close — or closes prematurely — the control board will lock out the furnace and prevent heating. Common symptoms include a furnace that starts the inducer but never advances to ignition, a flashing fault code indicating a pressure switch error, or a unit that intermittently loses heat during cold weather demand.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.

Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer if verifying inducer static pressure. Inspect the rubber hose port for cracks or blockages before installing the new switch, as a deteriorated hose is a common root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
