Dual run capacitors supply the starting and running current to two motors from a single unit, keeping wiring clean and replacing two separate capacitors with one component. Licensed HVAC technicians install this type of capacitor as a direct replacement when a failed or out-of-tolerance capacitor causes hard-start conditions, motor failure to run, or system shutdown on high amp draw.\u003c\/p\u003e\n\u003cp\u003eThe M12180 is suited for residential and light commercial split-system air conditioners and heat pumps where a single oval dual run capacitor serves both the compressor and the condenser fan motor. Its oval form factor fits standard capacitor brackets found in most outdoor condensing units. Technicians typically reach for this part during cooling season service calls when capacitance readings fall outside the plus or minus 5 percent tolerance range required for reliable motor operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual run capacitor supports both compressor and condenser fan motor from a single unit\u003c\/li\u003e\n  \u003cli\u003e20\/5 MFD rating covers common compressor and fan motor pairings in residential condensing units\u003c\/li\u003e\n  \u003cli\u003e440-volt rating provides margin above standard 370-volt systems, extending service life\u003c\/li\u003e\n  \u003cli\u003eOval form factor fits most OEM condensing unit capacitor brackets without modification\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 residential and light commercial air conditioning and heat pump condensing units requiring a 20\/5 MFD, 440-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 condensing unit before accessing the control compartment. Capacitors store a lethal electrical charge even after power is removed — discharge the capacitor through a resistor before handling or removing any terminals. Follow local codes and the equipment manufacturer's wiring diagram when reconnecting leads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 20\/5 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 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: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744121800\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: M12180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383316545842,"sku":"M12180","price":30.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670744.png?v=1782593229","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12180-dual-run-capacitor-20-5-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
