{"product_id":"terminal-board-fuse","title":"Sta-Rite Terminal Board Fuse","description":"\u003cp\u003eSta-Rite 32850-0099 is the terminal board fuse for the Max-E-Therm SR-200, SR-333 and SR-400 heaters. It is a new OEM Sta-Rite part, and it is also listed within the Pentair MasterTemp gas heater electrical and burner system parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the fuse protects\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe terminal board carries the low voltage control side of the heater. The fuse sits in that circuit so that a surge, a shorted sensor lead or a failed component opens the fuse rather than cooking the board behind it. That makes it a deliberately cheap sacrificial part in an assembly that is not cheap at all.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to suspect it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA Max-E-Therm that shows nothing on the panel, with power confirmed at the heater, is a classic blown terminal board fuse. Checking the fuse takes minutes and rules out the least expensive cause before anyone starts pricing a control board.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo not stop at the fuse\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf the replacement opens again right away, the fuse is doing its job and reporting a real fault. Trace the short or the failed component before fitting another one, because repeat fuse failures are a symptom rather than the problem.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48629115355348,"sku":"STA-151-6232","price":16.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_58cb980d-ba74-4d72-8eee-29ea81bc5901.jpg?v=1788759784","url":"https:\/\/www.activepoolsupply.com\/products\/terminal-board-fuse","provider":"Active Pool Supply","version":"1.0","type":"link"}
