Pressure switches prove that the inducer motor is generating adequate airflow before allowing ignition to proceed. When either switch fails or sticks open, the system will lock out prior to the ignition sequence, leaving you with no heat and often a blinking fault code on the control board. A failed pressure switch is one of the most common causes of a furnace or heat pump system that runs the inducer but never advances to ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 — High Pressure Switch | 312926-258 — Low Pressure Switch | 24V control circuit compatible | Factory-calibrated water column (W.C.) trip point matched to CH13NA03600GAAAA inducer specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to the exact W.C. rating required by this model. Generic switches frequently ship with incorrect trip points, causing nuisance lockouts or — worse — failing to detect a true blocked flue condition, which is a safety hazard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power before servicing. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (continuity test). Inspect the rubber hose port and pressure tubing for cracks or blockages before replacing the switch, as a clogged port is a common root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.

Always confirm the OEM part number printed on your existing switch before ordering, as high and low pressure switch trip points are not interchangeable. If you are unsure which switch has failed, our HVAC parts specialists can help verify fitment and diagnose the fault code before you order.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62909634347379,"sku":"CARRIE-CH13NA03600GAAAA-PRESSURE_SWITCH-312926-252","price":27.0,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62909634380147,"sku":"CARRIE-CH13NA03600GAAAA-PRESSURE_SWITCH-312926-252-GEN","price":19.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-draft-inducer-312926-252_a57dc2b5-7bac-4af3-aaff-f55a8d65cbf8.jpg?v=1782930427","url":"https:\/\/nationalhvacparts.com\/products\/carrier-ch13na03600gaaaa-pressure-switch-1vlc9v","provider":"National HVAC Parts","version":"1.0","type":"link"}
