It is separate from the thermostat that holds your set temperature, and its only job is to shut the heater down if water temperature climbs past the point the heater is allowed to run at. Without a working one, an overtemperature condition has nothing to stop it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing a high limit fault\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHeaters that lock out on high limit fall into two groups. Either the water really is getting too hot, which almost always comes back to flow, a dirty filter, a closed or partly closed valve, a struggling pump, or the sensor itself has failed and is reporting a temperature that is not there. Work through the flow side first. If the flow is good and the heater still trips, the sensor is the part to change.\u003c\/p\u003e","brand":"Jandy","offers":[{"title":"Default Title","offer_id":48634295943380,"sku":"LAR-151-3232","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1359da61-bbef-4f82-a16a-5fcaeff7f85f.jpg?v=1788828302","url":"https:\/\/www.activepoolsupply.com\/products\/zodiac-r0592300-high-limit-temperature-sensor-for-model-200-260-400-jxitm-heaters","provider":"Active Pool Supply","version":"1.0","type":"link"}
