If the control cannot see flame within its trial period, it shuts the gas valve and locks out. That is a safety design, not a fault, which is why a sensor that has fouled or failed produces a heater that fires briefly and then quits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the ETI 400 kit specifically. Other ETI 400 components, including the burner assembly, are separate Pentair parts, so confirm which piece of the ignition system has failed before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625840521428,"sku":"PUR-151-0316","price":51.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3ea00289-19ed-47b7-b290-572ad634be03.jpg?v=1788701293","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-462023-flame-sensor-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
