The pressure switch is a safety device that monitors inducer motor operation by proving adequate negative pressure in the flue before the control board advances to the ignition sequence. When this switch fails — or if its sensing hose becomes cracked, kinked, or waterlogged — the system will lock out before ignition, leaving you with a no-heat call and a pressure switch fault code on the board.\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 sensing hose | Factory-calibrated setpoints — no field adjustment required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory setpoints. Aftermarket pressure switches frequently carry ±15% W.C. tolerances that cause nuisance lockouts or, worse, fail to trip on a true inducer fault — a safety hazard.
