The pressure switch monitors inducer draft pressure to confirm that the heat exchanger is properly vented before allowing ignition to proceed. When it fails or sticks, the control board will not advance past the inducer stage — resulting in a no-heat lockout, a flashing fault code, or a system that runs the inducer fan indefinitely without igniting.\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 #: HK02ZB038 | Cross-reference: PS80-02-F0074\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM pressure switch manufactured to exact factory tolerances.
