The pressure switch monitors the inducer blower motor to prove adequate airflow before allowing the control board to advance through the ignition sequence. When this switch fails — or if the inducer motor is weak — the furnace or heat section will lock out before any ignition attempt, leaving you with a no-heat call. Common symptoms include a flashing fault code indicating \"pressure switch open,\" the unit short-cycling through inducer pre-purge, or a system that simply refuses to light.\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 length | Single-port design | Factory-matched set-point tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact set-point specifications.
