It watches water temperature and shuts the heater down if that temperature climbs past its setpoint, which protects the heat exchanger and everything downstream of it. Because it is a safety device, it is not a part to bypass or defeat when it starts acting up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis switch is listed for the Jandy Laars Lite and Lite2, Series 2, LX and LT, the Lite2 model LJ, the LXi, and the Laars XL-2 and oil fired XL-3. Laars uses limit switches at more than one temperature rating, so confirm that 150 F is the rating your heater specifies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA limit that trips repeatedly is frequently reporting a real problem rather than failing. Low flow from a dirty filter, a closed valve or a tired pump, and scale in the heat exchanger, all show up as nuisance limit trips. Rule those out first, then replace the switch if it is genuinely faulty.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48629105590484,"sku":"LAR-151-2540","price":50.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bd4b9c39-2638-4294-a1b1-6670d8f2553c.jpg?v=1788759750","url":"https:\/\/www.activepoolsupply.com\/products\/high-limit-switch-150-f","provider":"Active Pool Supply","version":"1.0","type":"link"}
