This 45\/5 MFD capacitor provides the electrical boost needed to start and run both the compressor and fan motor in your RV's AC unit. If your air conditioner won't start, runs intermittently, or the compressor hums without starting, a failed capacitor is often the culprit. This genuine Dometic replacement ensures reliable performance and proper electrical specifications for your cooling system.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#dc2626;margin:32px 0 16px;padding-bottom:10px;border-bottom:3px solid #dc2626;\"\u003eKey Features\u003c\/h2\u003e\n\u003cul style=\"line-height:1.8;margin-bottom:24px;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Capacitance Rating:\u003c\/strong\u003e 45 MFD for compressor start\/run, 5 MFD for fan motor operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Dometic OEM Part:\u003c\/strong\u003e Engineered to exact specifications for Dometic rooftop AC units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Rated:\u003c\/strong\u003e Designed to withstand the extreme heat conditions inside RV roof-mounted air conditioners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Fits multiple Dometic rooftop air conditioner models with matching electrical requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical AC Component:\u003c\/strong\u003e Essential for proper compressor and fan motor startup and operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional-Grade Construction:\u003c\/strong\u003e Metal housing with secure terminal connections for reliable electrical performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#dc2626;margin:32px 0 16px;padding-bottom:10px;border-bottom:3px solid #dc2626;\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table table-bordered table-sm\" style=\"margin-bottom:24px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;width:40%;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e3310711.001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eCapacitance Rating\u003c\/td\u003e\n\u003ctd\u003e45\/5 MFD (Microfarads)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eVoltage Rating\u003c\/td\u003e\n\u003ctd\u003e370 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eRooftop Air Conditioner - Compressor \u0026amp; Fan Motor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eCapacitor Type\u003c\/td\u003e\n\u003ctd\u003eDual Run Capacitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eTerminal Configuration\u003c\/td\u003e\n\u003ctd\u003eMulti-terminal (Common, HERM, Fan)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#dc2626;margin:32px 0 16px;padding-bottom:10px;border-bottom:3px solid #dc2626;\"\u003eCompatible Models\u003c\/h2\u003e\n\u003cp style=\"margin-bottom:12px;\"\u003eThis capacitor is designed for Dometic rooftop air conditioners requiring 45\/5 MFD dual-run capacitors.

If your AC worked fine then suddenly stopped, the capacitor is a prime suspect. Always disconnect power before inspecting electrical components.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom:20px;\"\u003e\n\u003ch3 style=\"font-size:16px;font-weight:700;color:#333;margin-bottom:8px;\"\u003eCan I substitute a different MFD rating?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eNo. Capacitors must match the exact MFD ratings specified by the manufacturer. Using incorrect capacitance values can cause motor damage, reduced cooling efficiency, or complete system failure. Always replace with the same 45\/5 MFD rating for proper compressor and fan operation.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom:20px;\"\u003e\n\u003ch3 style=\"font-size:16px;font-weight:700;color:#333;margin-bottom:8px;\"\u003eIs this a DIY repair or should I hire a technician?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eIf you're comfortable working with electrical components and can safely access your rooftop AC unit, capacitor replacement is straightforward. However, it involves 120V AC power and requires proper safety precautions. Always disconnect shore power and turn off breakers before working on AC units. If you're unsure, consult a qualified RV technician.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom:20px;\"\u003e\n\u003ch3 style=\"font-size:16px;font-weight:700;color:#333;margin-bottom:8px;\"\u003eHow long do AC capacitors typically last?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eRV AC capacitors typically last 5-10 years depending on usage and climate conditions. Extreme heat, frequent cycling, and voltage fluctuations can shorten lifespan.
