The pressure switch monitors negative pressure created by the inducer motor to confirm proper draft before allowing ignition to proceed. When it fails or sticks open, the control board cannot verify inducer operation and the unit locks out — producing a no-heat condition before a single ignition attempt is ever made. Common symptoms include a fault code for \"pressure switch open,\" continuous inducer run with no ignition, or intermittent heating lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Close pressure: 22\" W.C. | Open pressure: 7\" W.C. | Lead length: 50\" | OEM Part Number: HK02ZB038 | Single-port design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch calibrated to exact factory W.C. thresholds.
