Dual run capacitors serve two loads simultaneously, typically the compressor and the condenser fan motor, in a single oval-shaped housing. This reduces cabinet space requirements compared to two separate capacitors. The oval form factor measures 1.806 inches wide by 2.806 inches long by 4.25 inches tall, making it a compact fit for most condenser unit capacitor brackets. Licensed HVAC technicians install and replace this component during routine maintenance or when a failed capacitor is identified as the cause of compressor or fan motor startup failure.\u003c\/p\u003e\n\u003cp\u003eThis capacitor is used in residential and light commercial air conditioning and heat pump systems where the condenser unit relies on a single dual run capacitor to energize both the compressor and the condenser fan motor. It is a common replacement component serviced during cooling season maintenance, after hard-start diagnostics, or when capacitance testing reveals a reading outside acceptable tolerance. The oval housing fits standard capacitor brackets found in a wide range of split-system condensers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual run design supports two motor loads from one capacitor housing\u003c\/li\u003e\n  \u003cli\u003e45\/5 MFD rating covers both compressor and condenser fan motor circuits\u003c\/li\u003e\n  \u003cli\u003e370-volt rating suitable for standard single-phase residential condenser units\u003c\/li\u003e\n  \u003cli\u003eOval housing fits common condenser unit capacitor mounting brackets\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions minimize space requirements inside the condenser cabinet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dual run capacitor for single-phase residential and light commercial air conditioning and heat pump condenser units requiring a 45\/5 MFD 370-volt oval capacitor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCapacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out all power to the condenser unit before opening the electrical access panel. Capacitors store a charge even after power is removed and must be safely discharged using an insulated discharge tool before handling. Follow NEC guidelines and local electrical codes when replacing capacitors in HVAC equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 45\/5 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 370 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Oval\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.806 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.806 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744121749\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M12174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383533338930,"sku":"M12174","price":33.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670743.png?v=1782599684","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12174-dual-run-capacitor-45-5-mfd-370v-oval","provider":"Voomi Supply","version":"1.0","type":"link"}
