It is the genuine Hayward part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA note on the name\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward source material refers to this part number both as the defrost sensor and as a water temperature sensor. We have carried both readings rather than pick one. Before fitting, match the sensor and its lead against the position it came from on your unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy a sensor causes big symptoms\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump has no way to know what is happening beyond what its sensors tell the control board. When a sensor drifts or opens, the board keeps making decisions, just on wrong information. That is why a failing sensor rarely announces itself as a sensor problem. It looks like a unit that ices over, cycles on and off, or sits there refusing to heat a pool that is plainly cold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWorth checking first\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSensors sit near the bottom of the price list for heat pump components and near the top of the failure list. On a HeatPro that is behaving oddly without any obvious mechanical fault, sensors are the sensible place to start.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634443858132,"sku":"HAY-151-11024169","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_175618ea-93be-4a58-9000-98db8e73f8fe.jpg?v=1788830535","url":"https:\/\/www.activepoolsupply.com\/products\/defrost-sensor-for-heat-pump","provider":"Active Pool Supply","version":"1.0","type":"link"}
