The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When this switch fails or becomes stuck, the control board receives no proof-of-inducer signal and the system will lock out — preventing heating entirely. Common symptoms include a system that powers on but never reaches ignition, an inducer motor that runs but the burners never fire, or a fault code indicating a pressure switch open condition.\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\" wire leads | OEM part number HK02ZB038 | Factory-matched setpoints for proper inducer proving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch, manufactured to exact factory pressure setpoints (±0.1\" W.C.).
