It is built to fail at a set temperature, and when the heater gets hotter than it should the link melts, the circuit opens and the heater stops. That is the whole design: it gives up so the heat exchanger, the burner tray and the surrounding cabinet do not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing a dead heater\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heater that will not fire at all, with no obvious fault on the control board, is often a blown link. It is a cheap part and an easy check on the parts breakdown for your model. What it is not is a fix on its own.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFind out why it opened\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe link only goes when something has overheated the unit. Restricted water flow is the most common cause, from a dirty filter, a closed valve or an undersized pump. A scaled or soot fouled heat exchanger and a blocked or poorly drawing vent do the same. Sort the cause out first, or the replacement link will do exactly what the last one did.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48634802667732,"sku":"LAR-151-2545","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_56fa9316-d6de-4939-87d3-1e356c059318.jpg?v=1788837671","url":"https:\/\/www.activepoolsupply.com\/products\/fusible-link","provider":"Active Pool Supply","version":"1.0","type":"link"}
