Run capacitors maintain a continuous phase shift to keep PSC motors running smoothly after startup. This capacitor is rated at 370 volts and 4 MFD, making it a compact unit suited for fan motors and compressors in residential and light commercial cooling systems. Licensed HVAC technicians handle replacement of this component as part of routine service or failure diagnosis on air conditioning and heat pump systems.\u003c\/p\u003e\u003cp\u003eThis capacitor fits applications where an oval-form-factor run capacitor is required. Oval capacitors are commonly installed in tight equipment compartments where round capacitors may not seat properly. Typical install scenarios include condenser fan motor replacements, OEM capacitor substitutions during seasonal tune-ups, and field repairs following capacitor failure on split-system air conditioners and heat pumps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 MFD capacitance rating for precision motor support\u003c\/li\u003e\n\u003cli\u003e370-volt rating suitable for standard residential HVAC equipment\u003c\/li\u003e\n\u003cli\u003eOval form factor fits space-constrained equipment compartments\u003c\/li\u003e\n\u003cli\u003eCompact dimensions support installation in high-density wiring areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement run capacitor for residential and light commercial HVAC systems requiring a 4 MFD, 370-volt oval capacitor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eRun capacitor replacement is performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before accessing the capacitor, and discharge the capacitor fully before handling, as run capacitors can retain a lethal charge even after power is removed. Use insulated tools and follow NEC guidelines for low-voltage component replacement. Verify that the replacement MFD and voltage ratings match the equipment nameplate before installing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 4 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 370 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.056 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.212 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744120049\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: M12004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383774544178,"sku":"M12004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670834.png?v=1782607064","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12004-run-capacitor-4-mfd-370v-oval","provider":"Voomi Supply","version":"1.0","type":"link"}
