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 the switch fails or sticks open, the control board cannot verify inducer operation and the furnace will lock out — typically before a single ignition attempt — leaving you with no heat and a flashing fault code. Common symptoms include a continuously running inducer with no ignition, nuisance lockouts, or intermittent no-heat calls.\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\" | Replaces OEM part HK02ZB038 | Factory-matched set point for exact trip accuracy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine OEM Carrier pressure switch manufactured to factory tolerances.
