The pressure switch proves that the inducer motor has created adequate negative pressure (draft) before allowing the ignition sequence to proceed. When this switch fails — or fails to close — the control board receives no confirmation of proper venting, causing the system to lock out before ignition. Common symptoms include a furnace or packaged unit that runs the inducer but never attempts to light, error codes indicating an open pressure switch, or intermittent heating failures on cold-start.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at \u003cstrong\u003e7 PSI\u003c\/strong\u003e | Closes at \u003cstrong\u003e22 PSI\u003c\/strong\u003e | \u003cstrong\u003e50\" wire leads\u003c\/strong\u003e | 24V control circuit | Country of Origin: Mexico\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 tolerances. OEM pressure switches meet precise W.C. ratings and design-life testing. Aftermarket alternatives often drift out of spec, causing nuisance lockouts or — worse — failing to detect a true venting fault.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the unit and confirm inducer is off before servicing. Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter (to verify switch continuity). Disconnect the two leads and hose port, swap the switch, and re-confirm proper draft operation before restoring power. Always verify pressure switch operation with a manometer if nuisance lockouts continue after replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
