Run capacitors maintain a continuous phase shift to keep compressor and fan motors operating efficiently under load. The 12223 uses a compact round case that fits standard capacitor brackets and disconnect pulls. HVAC technicians replace run capacitors as a routine service repair when a motor exhibits hard-start symptoms, fails to start, or draws elevated amperage due to capacitor degradation.\u003c\/p\u003e\n\u003cp\u003eThis capacitor is suited for single-phase compressor motors, condenser fan motors, and air handler blower motors operating on 370-volt circuits. It is a common replacement part in residential split systems and package units where 45 MFD run capacitors are called out on the unit nameplate. The round form factor fits most standard capacitor mounting brackets found in condensing units and air handlers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45 MFD capacitance rating for consistent motor run support\u003c\/li\u003e\n  \u003cli\u003e370-volt AC rating suitable for standard residential HVAC circuits\u003c\/li\u003e\n  \u003cli\u003eRound case design fits standard capacitor brackets and pull-out disconnects\u003c\/li\u003e\n  \u003cli\u003eSupports PSC compressor motors, condenser fan motors, and blower motors\u003c\/li\u003e\n  \u003cli\u003eDirect replacement form factor for 45 MFD 370V round run capacitors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for single-phase PSC motors in residential and light commercial HVAC equipment requiring a 45 MFD 370-volt round run capacitor. Always verify the MFD rating and voltage rating on the unit nameplate before installation.\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 unit before handling any capacitor — capacitors store a lethal electrical charge and must be safely discharged before removal. Use an insulated discharge tool or resistor across the terminals prior to disconnecting leads. Verify that the replacement capacitor MFD rating and voltage rating match the values printed on the equipment nameplate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 45 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 370 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Style\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 68574412223\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: MARS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51383892967730,"sku":"12223","price":29.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678776.jpg?v=1782610871","url":"https:\/\/voomisupply.com\/products\/mars-12223-round-run-capacitor-45-mfd-370v","provider":"Voomi Supply","version":"1.0","type":"link"}
