This 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—and this is the genuine Dometic replacement part.\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-Run Design:\u003c\/strong\u003e 55 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 reliable performance and proper fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Rated:\u003c\/strong\u003e Built to withstand the extreme heat conditions inside rooftop AC units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Mounts in original capacitor location with existing hardware and wiring connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOval Metal Housing:\u003c\/strong\u003e Durable construction with clearly marked terminals for proper installation\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\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\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;width:35%;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e3313107.036\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\u003e55\/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;\"\u003eCapacitor Type\u003c\/td\u003e\n\u003ctd\u003eDual Run (Compressor + Fan)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eHousing Style\u003c\/td\u003e\n\u003ctd\u003eOval Metal Can\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\u003e3-Terminal (Common, Compressor, Fan)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight:600;background:#f8f9fa;\"\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eDometic Rooftop Air Conditioners\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;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv style=\"margin-bottom:20px;\"\u003e\n\u003ch3 style=\"font-size:16px;font-weight:700;color:#333;margin-bottom:8px;\"\u003eHow do I know if my AC capacitor has failed?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;color:#666;\"\u003eCommon signs include: AC won't start at all, compressor hums but doesn't run, AC runs briefly then shuts off, fan runs but compressor doesn't start, or visible bulging\/leaking from the capacitor itself. Capacitors can fail due to age, heat exposure, or electrical surges. If your AC is more than 5 years old and showing these symptoms, the capacitor is a likely cause.\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 or substitute another brand?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;color:#666;\"\u003eNo—capacitor ratings must match exactly. Using the wrong MFD rating can cause compressor damage, reduced cooling efficiency, or complete system failure. The 55 MFD side powers the compressor while the 5 MFD side runs the fan motor. Always use the Dometic-specified capacitor for your unit to ensure proper operation and avoid voiding warranties on other 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;\"\u003eIs this a DIY repair or do I need a technician?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;color:#666;\"\u003eCapacitor replacement is straightforward for those comfortable with basic electrical work, but safety is critical. You must disconnect all power, discharge the old capacitor properly (capacitors store electrical charge even when power is off), and connect wires to the correct terminals. If you're not experienced with AC electrical systems, hire a qualified RV technician. Improper installation can damage your AC unit or create safety hazards.\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;\"\u003eWill this capacitor fit my Dometic AC model?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;color:#666;\"\u003eThis capacitor is used across many Dometic rooftop AC models. To verify compatibility, check your current capacitor's label for the 55\/5 MFD rating and 370V specification, or reference your AC unit's model number in the Dometic parts manual. The capacitor is typically located in the electrical compartment of the rooftop unit, mounted near the compressor. If your existing capacitor matches these specs, this is your replacement.\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 that keep your RV systems running smoothly.
