The pressure switch is a critical safety device that monitors the negative pressure (vacuum) created by the draft inducer motor before allowing the ignition sequence to proceed. When it fails or sticks open, the furnace will attempt to start, fail to prove inducer operation, and lock out — leaving you with no heat. A failed pressure switch is one of the most common causes of furnace lockout codes on Carrier gas furnaces.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole Single-Throw) | 0.27\" WC Break Set Point | 0.42\" WC Max Break | Pilot Duty 28VA @ 24VAC | High-Fire rated | OEM Part # HK06WC091 | Includes pressure tube variant HK06WC092\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch manufactured to exact factory set-point tolerances. Generic aftermarket switches often have imprecise WC ratings that can cause nuisance lockouts or — more dangerously — fail to detect an inducer fault, creating a flue gas safety risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Straightforward replacement accessible from the furnace cabinet. Tools needed: Phillips screwdriver, 1\/4\" nut driver, needle-nose pliers. Always shut off gas and power before servicing. Inspect the pressure tube for cracks or blockage before condemning the switch — a blocked or cracked 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.
