Do not attempt to service gas or high-voltage components without proper certification.\u003c\/p\u003e\n\n\u003cp\u003eThe vent pressure switch monitors combustion air and flue gas flow through the heat exchanger vent system. When adequate airflow is confirmed, the switch signals the control board to allow the burner to fire. A faulty or failed switch will prevent the heater from igniting, making this a common service part when the heater locks out despite normal gas supply and water flow.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eFDXLVPS1930\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e610377099387\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eChannel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eOpen Line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cem\u003eNo compatibility data is available in OEM records at this time.

If the heater resumes igniting after clearing any obstruction, the original switch may still be serviceable. When the switch itself has failed (open circuit at rest, or closed circuit regardless of airflow), replace it with this OEM unit to restore the manufacturer's original pressure calibration. All diagnosis and replacement must be performed by a licensed pool professional or qualified HVAC technician.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303486050579,"sku":"FDXLVPS1930","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-vent-pressure-switch-kit-fdxlvps1930.webp?v=1785748529","url":"https:\/\/poolaroo.com\/products\/hayward_fdxlvps1930","provider":"Poolaroo","version":"1.0","type":"link"}
