{"product_id":"thermostat-control","title":"Raypak Genuine OEM Mechanical Thermostat Control","description":"\u003cp\u003eThe Raypak 003346F is the genuine OEM mechanical thermostat temperature control. It is listed for the ELS 552-2 and 1102-2 models and for the 53A, 53B, 055A, 055B and 105A millivolt pool heater and electric spa units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the thermostat does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe thermostat is the part that decides whether the heater runs. It senses water temperature and closes the circuit that lets the heater fire until the setting is reached. When it fails, one of two things happens: the heater never lights even though water is flowing and gas is available, or it lights and keeps heating past the set point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRaypak used more than one temperature control across its heater range, and the fitment list above is what the source data carries for this part. Check the model and serial plate on your heater against that list. If the heater is a digital model rather than a millivolt one, it uses a different control entirely.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48628735869140,"sku":"RAY-151-3564","price":128.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bed04eb7-c89c-4ccd-8a83-90c1419e4149.jpg?v=1788749402","url":"https:\/\/www.activepoolsupply.com\/products\/thermostat-control","provider":"Active Pool Supply","version":"1.0","type":"link"}
