Temperature limiters are safety-critical thermal cutoff components that interrupt heater operation when internal temperatures exceed safe thresholds, protecting the heater from heat-exchanger damage and unsafe operating conditions.\u003c\/p\u003e\n\n\u003cp style=\"background-color: #fff3cd; border: 2px solid #FFEAA7; padding: 15px; border-radius: 5px; margin: 15px 0; color: #856404;\"\u003e\u003cstrong\u003eIMPORTANT: PROFESSIONAL SERVICE REQUIRED\u003c\/strong\u003e\u003cbr\u003eGas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician.

When heater internal temperatures reach the limiter's rated threshold, the device interrupts the heating circuit to prevent damage and unsafe operation. Replacing worn or tripped temperature limiters restores the heater's ability to monitor and respond to thermal conditions correctly.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eHAXTLK1930\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eTemperature Limiters Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eChannel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eOpen Line\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e610377625814\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePoolaroo Pro Tip\u003c\/h3\u003e\n\u003cp\u003eA temperature limiter that trips repeatedly is often a symptom of a root cause — restricted water flow, a failing pressure switch, or scale buildup on the heat exchanger. Before replacing the limiter kit, confirm that water flow through the heater meets the manufacturer's minimum flow rate requirement. Replacing the limiters without addressing the underlying cause will result in repeat failures. Consult your heater's installation manual for minimum flow specifications and have a licensed pool professional inspect the system if thermal shutdowns recur.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303483134227,"sku":"HAXTLK1930","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-temperature-limiters-kit-for-hayward-heaters-haxtlk1930.webp?v=1783492344","url":"https:\/\/poolaroo.com\/products\/hayward_haxtlk1930","provider":"Poolaroo","version":"1.0","type":"link"}
