The sense rod supplies that proof: it sits in the flame and passes a very small rectified current back to the control. If the control cannot read that current, it shuts the gas within seconds, no matter how well the heater lit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptom to look for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heater that ignites cleanly and then drops out a few seconds later is almost always a sensing problem rather than an ignition problem. Carbon, oxide, a bent rod or a cracked ceramic insulator all cut the current the control is looking for. Cleaning helps a lightly coated rod; a pitted or cracked one gets replaced.\u003c\/p\u003e","brand":"Waterpik Technologies","offers":[{"title":"Default Title","offer_id":48633768640724,"sku":"LAR-151-1028","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d98f3404-32d4-4c43-8fa7-4b83d8dd75af.jpg?v=1788815003","url":"https:\/\/www.activepoolsupply.com\/products\/flame-sense-rod","provider":"Active Pool Supply","version":"1.0","type":"link"}
