The pressure switch monitors the operation of the inducer\/draft motor by sensing negative air pressure through a hose connected to the housing. When the inducer reaches proper speed and draws sufficient pressure, the switch closes and allows the control board to advance to the ignition sequence. A failed pressure switch will keep the system locked out before ignition — symptoms include a system that runs the inducer but never fires the burners, a flashing fault code indicating a pressure switch open condition, or a unit that repeatedly cycles the inducer without advancing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Closes at 22\" W.C. | Opens at 7\" W.C. | 50\" lead wire | Single-port hose connection | OEM-matched setpoints for factory precision\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part with exact factory pressure calibration. Aftermarket switches frequently carry ±15% W.C. tolerances, causing nuisance lockouts or — worse — allowing the unit to fire under unsafe draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the unit at the disconnect before beginning. Tools needed: flathead screwdriver, needle-nose pliers, and a phone camera to photograph hose routing before disconnecting. Inspect the pressure hose for cracks or clogs before installing the new switch, as a blocked hose is the most common root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.
