The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor. Before each ignition cycle, the furnace control board checks that the inducer has established proper airflow — if the pressure switch fails to close (or fails to open), the control board will lock out ignition entirely, leaving the system with no heat. Common failure symptoms include a system that starts then immediately goes into lockout, a flashing fault code indicating pressure switch failure, or an inducer motor running continuously with no ignition sequence ever beginning.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications:\u003c\/strong\u003e Opens at 7\" W.C. | Closes at 22\" W.C. | 50\" lead wire harness | 24V control circuit | Factory-matched OEM tolerances | Country of Origin: Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is the genuine Carrier OEM part — not an aftermarket approximation.
