A run capacitor stays in the circuit continuously. They are NOT interchangeable — a start cap left in the circuit will overheat and explode. Start caps are typically black cylinders with much higher MFD values than run caps.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch4\u003eWhy does the MFD have a range instead of a fixed value?\u003c\/h4\u003e\n\u003cp\u003eStart capacitors use electrolytic construction with wider tolerances than run capacitors. The 270-324 MFD range means the actual capacitance falls somewhere in that range. As long as the range overlaps with your original cap's range, it will work correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eFitment Guaranteed\u003c\/strong\u003e — if this capacitor doesn't work in your system, we'll send the right one or refund you.\u003c\/p\u003e\n\u003cp\u003eShips same-day from Houston, TX on orders before 3PM CST.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"National HVAC Parts","offers":[{"title":"Default Title","offer_id":63008717537651,"sku":"NHVAC-CAP-0VOPG0","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/61VMxmR3pgL._AC_SL1500.jpg?v=1782073999","url":"https:\/\/nationalhvacparts.com\/products\/270-324-mfd-110-125v-start-capacitor-universal-motor-starting","provider":"National HVAC Parts","version":"1.0","type":"link"}
