It is the genuine Laars replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the heater needs it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOnce the burner lights, the control has to be told the flame is really there before it will hold the gas valve open. The sense rod does that. It sits in the flame and passes a small current that the control reads as proof of ignition. Lose that signal and the control shuts the heater down, because the alternative is gas flowing with nothing burning.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptom to look for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heater that ignites, runs for a handful of seconds, then drops out and goes to lockout is the classic flame sensing failure. Sometimes the rod is simply coated and can be cleaned, but a rod that has failed or been cleaned too many times is due for replacement. Check that yours is the Low NOx version of the LX or LT before ordering, since the earlier models use different parts.\u003c\/p\u003e","brand":"Waterpik Technologies","offers":[{"title":"Default Title","offer_id":48634422165716,"sku":"LAR-151-3870","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/LAR-151-3870_1a.png?v=1788830300","url":"https:\/\/www.activepoolsupply.com\/products\/flame-sense-rod-lx-lt-low-nox","provider":"Active Pool Supply","version":"1.0","type":"link"}
