When the water temperature it senses goes above its setting, it opens and stops the heater firing. That is a deliberate shutdown, not a fault in itself, and it is the control that keeps a heater from cooking itself when flow drops away.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heater that trips on high limit is often reporting a flow problem rather than a bad switch. Check the filter, the valves and the pump before condemning the switch. If flow is right and the heater still shuts down early, the assembly is the part to change.\u003c\/p\u003e","brand":"Waterpik Technologies","offers":[{"title":"Default Title","offer_id":48633780764884,"sku":"LAR-151-7238","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c5260919-e515-4fb8-b7fc-10158acda5cc.jpg?v=1788816147","url":"https:\/\/www.activepoolsupply.com\/products\/high-limit-switch-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
