Raypak lists it for the Model 207A Digital Low NOx pool heater and for 331 - 405, 336, 366, 406, 407 and 408 D-2 power vent models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the switch does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBefore a gas heater is allowed to light, something has to confirm that the blower is really moving air. That is the air pressure switch. It senses the pressure the blower develops and closes a contact to tell the control board it is safe to proceed. No switch closure, no ignition.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptoms\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA failed pressure switch usually shows up as a heater that will not fire at all, or one that starts its ignition sequence and locks out part way through. Worth knowing: the switch is often perfectly good and is reporting a genuine airflow problem, such as a blocked vent or a tired blower. Check the air path before you condemn the switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrdering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRaypak uses different pressure switches across the 207A, 267A, 337A and 407A range. Order by the part number on the switch you are replacing, 008135F, rather than by the heater model alone.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48627616940244,"sku":"RAY-151-1395","price":68.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_12b11f92-9da9-4f9a-8aa3-b818f2a7695e.jpg?v=1788725403","url":"https:\/\/www.activepoolsupply.com\/products\/air-pressure-switch-267a","provider":"Active Pool Supply","version":"1.0","type":"link"}
