The can measures 2\" across by 3-3\/4\" tall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatching the part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA run capacitor is chosen by two numbers, the capacitance in MFD and the voltage rating, both of which are printed on the side of the old part. Both have to match, with the one exception that a higher voltage rating is acceptable and a lower one is not. The source also carries a set of substitute numbers used by other suppliers, including RD50370, 3190029, 17586350, 319-0029, 628318313 and 628318-313, which is useful when the number stamped on your failed capacitor is not the U.S. Seal one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you start\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCut power at the breaker and discharge the capacitor before you touch the terminals. A capacitor holds a charge after the motor has stopped, which is the part of the job that catches people out. If the motor hums but will not spin, or starts slowly and runs hot, the capacitor is a common cause and a cheap thing to rule out.\u003c\/p\u003e","brand":"US Seal","offers":[{"title":"Default Title","offer_id":48633714147540,"sku":"USS-601-5162","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_f6a8a5e2-2297-4477-b438-cfcb61dde23f.jpg?v=1788812385","url":"https:\/\/www.activepoolsupply.com\/products\/run-capacitor-50-mfd-370v","provider":"Active Pool Supply","version":"1.0","type":"link"}
