The pressure switch is a critical safety component that monitors inducer motor operation by detecting the negative pressure (vacuum) created in the flue system. When the inducer fails to reach the correct RPM — or a hose, port, or diaphragm fails — the pressure switch will not close, preventing ignition and locking out the furnace to protect against unsafe flue conditions. Common symptoms of a failed pressure switch include a furnace that attempts to start and immediately locks out, an inducer that runs but heating never begins, or a blinking fault code indicating a pressure switch fault on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch, High Fire) — both factory-authorized Carrier\/Honeywell parts for this unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Cut-out setpoint: \u003cstrong\u003e6.5\" w.c.\u003c\/strong\u003e | SPST configuration | Compatible with natural gas and LP gas applications | Horizontal or vertical mounting | Replaces superseded part numbers HK02MB008 and HK06MC110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory water-column tolerances. Off-brand alternatives often carry ±15% setpoint variance, which can cause nuisance lockouts or — more dangerously — allow the furnace to fire under unsafe draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power and gas before servicing. Tools needed: 1\/4\" nut driver, flathead screwdriver, manometer (recommended for setpoint verification). Always inspect rubber hose connections and condensate ports before condemning the switch — a blocked port mimics switch failure.
