It is the genuine Hayward replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a contactor does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe contactor is the heavy duty switch inside the cabinet. The control side of the unit sends a low voltage signal to a coil, the coil pulls a set of contacts together, and full current reaches the compressor. Everything the heat pump does starts with that one set of contacts closing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy they fail\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eContacts arc slightly every time they open and close. Over years of cycling the faces pit, carbon builds up, and the contactor either stops passing current cleanly or welds itself shut. The usual symptom is a unit that seems to be trying: the board calls for heat, something clicks, and the compressor never comes on. A meter across the contactor confirms it quickly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSafety\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLine voltage is present inside a heat pump cabinet whether or not the unit is running. Shut off power at the breaker before opening it, and if you are not comfortable working on live equipment, have the part fitted by a qualified technician.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48633982320852,"sku":"HAY-151-5019","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_8e4c9454-31f0-4f9b-b0e9-cfdcd97f3544.jpg?v=1788823331","url":"https:\/\/www.activepoolsupply.com\/products\/contactor-for-heat-pump","provider":"Active Pool Supply","version":"1.0","type":"link"}
