High limit components are model-specific; installing an incorrect kit may prevent the safety circuit from functioning properly. Have a licensed pool technician or qualified HVAC professional perform the replacement to ensure the safety circuit is correctly tested after installation.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303486607635,"sku":"FDXLHLI1930","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-high-limit-kit-for-fd-series-heaters-fdxlhli1930.webp?v=1785919173","url":"https:\/\/poolaroo.com\/products\/hayward_fdxlhli1930","provider":"Poolaroo","version":"1.0","type":"link"}
