{"product_id":"high-limit-manual-reset-kit","title":"Raypak Thermostat Manual Reset Kit","description":"\u003cp\u003eRaypak 017143F is the manual reset kit for Raypak heaters. It appears in the catalog under two names, the thermostat manual reset kit and the high limit manual reset kit, and both refer to this part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a manual reset does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA high limit control shuts the heater down when temperature climbs past a safe point. The manual reset version will not come back on by itself once it has tripped. Somebody has to press it, which is intentional: it guarantees that a heater which has overheated is looked at by a person rather than quietly cycling back on.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you fit one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA limit that keeps tripping is usually reporting something else. Low flow from a dirty filter, a partly closed valve, a failing pump or a fouled heat exchanger all drive heater temperature up past the limit. Replace the reset kit when the control itself has failed, and chase the cause when it is tripping on a heater that is otherwise sound.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48633931923668,"sku":"RAY-151-1974","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_48b2087d-8144-444d-8905-47cff790b087.png?v=1788817523","url":"https:\/\/www.activepoolsupply.com\/products\/high-limit-manual-reset-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
