Dometic AC Capacitor 55/5 MFD - Dual Run Capacitor for Rooftop Air Conditioners - Part# 3313107.036
Dometic AC Capacitor 55/5 MFD - Dual Run Capacitor for Rooftop Air Conditioners - Part# 3313107.036
The Dometic 3313107.036 is a dual-run capacitor rated at 55/5 MFD, designed specifically for Dometic rooftop air conditioning units. 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.
Key Features
- Dual-Run Design: 55 MFD for compressor start/run, 5 MFD for fan motor operation
- Genuine Dometic OEM Part: Engineered to exact specifications for reliable performance and proper fit
- High-Temperature Rated: Built to withstand the extreme heat conditions inside rooftop AC units
- Direct Replacement: Mounts in original capacitor location with existing hardware and wiring connections
- Oval Metal Housing: Durable construction with clearly marked terminals for proper installation
- Critical AC Component: Essential for proper compressor and fan motor operation in your cooling system

Frequently Asked Questions
How do I know if my AC capacitor has failed?
Common 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.
Can I use a different MFD rating or substitute another brand?
No—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.
Is this a DIY repair or do I need a technician?
Capacitor 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.
Will this capacitor fit my Dometic AC model?
This 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.
