This 45\/10 MFD capacitor provides the electrical boost needed to start and run both the compressor and fan motor in your RV's AC system. 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 safe operation.\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, 10 MFD for fan motor operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Dometic OEM Part:\u003c\/strong\u003e Exact replacement for original equipment, ensuring proper fit and electrical specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Rated:\u003c\/strong\u003e Designed to withstand the extreme heat conditions inside RV rooftop AC units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Mounting:\u003c\/strong\u003e Standard terminal configuration fits most Dometic rooftop air conditioner models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical AC Component:\u003c\/strong\u003e Essential for proper compressor and fan motor operation in your cooling system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Eliminates guesswork with factory-specified capacitance values\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:35%;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e3311563.000\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\/10 MFD (Dual Run)\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;\"\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003eStandard Blade Terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eUniversal Bracket Mount\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;\"\u003eCompatibility\u003c\/h2\u003e\n\u003cp style=\"margin-bottom:12px;\"\u003eThis capacitor is designed for Dometic rooftop air conditioning units.

Capacitors can also bulge or leak when failed. 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 use a different MFD rating capacitor?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eNo. Using incorrect capacitance values can damage your compressor or fan motor, cause poor cooling performance, or create safety hazards. Always replace with the exact MFD rating specified by Dometic. The 45 MFD handles the compressor, while the 10 MFD runs the fan motor.\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 start capacitor or run capacitor?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eThis is a dual run capacitor, which means it provides both starting boost and continuous running support for the compressor and fan motor. It stays in the circuit during operation, unlike a start capacitor which only engages briefly during startup. Most modern Dometic rooftop ACs use dual run capacitors.\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;\"\u003eDo I need special tools to replace this capacitor?\u003c\/h3\u003e\n\u003cp style=\"margin:0;line-height:1.6;\"\u003eBasic tools are needed: screwdriver to access the AC unit, needle-nose pliers for wire terminals, and a voltage tester to confirm power is off. IMPORTANT: Capacitors store electrical charge even when power is disconnected. Discharge the capacitor safely with an insulated screwdriver across the terminals before handling. If you're not comfortable working with electrical components, hire a qualified RV technician.\u003c\/p\u003e\n\u003c\/div\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;\"\u003eWhy Choose Elkhart RV Parts?\u003c\/h2\u003e\n\u003cp style=\"line-height:1.8;margin-bottom:16px;\"\u003eAt ElkhartRVParts.com, we specialize in hard-to-find Dometic replacement parts for RV owners who need the right part the first time.
