It is a new OEM part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe heater runs its controls on low voltage. The transformer takes the incoming supply and steps it down to feed the control board, the ignition control and the switches around them. When it fails, the heater goes completely quiet: no display, no fan, no response to a call for heat, even though power is present at the unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore replacing it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA dead panel has more than one possible cause, so check for output on the secondary side before condemning the transformer. Isolate the heater at the breaker before opening the electrical compartment.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634258391252,"sku":"STA-151-6261","price":76.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_532957a1-3ccd-402a-8418-f30f700a4f7f.jpg?v=1788827819","url":"https:\/\/www.activepoolsupply.com\/products\/transformer-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
