The pressure switch is a critical safety component that monitors negative air pressure created by the inducer motor before allowing the ignition sequence to proceed. When the switch fails — or when the sensing hose, port, or inducer is compromised — the control board reads an open pressure switch circuit and locks out the system, resulting in no heat and a diagnostic fault code. Common symptoms include a furnace or packaged unit that powers on, runs the inducer, but never advances to ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Numbers \u003cstrong\u003eHK06WC085\u003c\/strong\u003e (standard) and \u003cstrong\u003eHK06WC097\u003c\/strong\u003e (with mounting bracket) | W.C.

Aftermarket switches frequently carry wider tolerance ratings, which can result in nuisance lockouts or, more dangerously, failure to detect true inducer faults — a safety risk. Choose OEM for reliability and code compliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Disconnect power before servicing. Tools needed: 1\/4\" nut driver, flathead screwdriver, manometer (recommended to verify W.C. after install). Inspect rubber sensing hose for cracks or blockage before replacing the switch — a clogged hose is a common root cause of pressure switch failure. Note: HK06WC097 includes a mounting bracket and may be required if the original bracket is damaged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
