Dometic AC Capacitor 45/10 MFD - Dual Run Capacitor for Rooftop Air Conditioners - Part# 3311563.000
Dometic AC Capacitor 45/10 MFD - Dual Run Capacitor for Rooftop Air Conditioners - Part# 3311563.000
The Dometic 3311563.000 is a dual run capacitor designed specifically for Dometic rooftop air conditioning units. 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.
Key Features
- Dual Capacitance Rating: 45 MFD for compressor start/run, 10 MFD for fan motor operation
- Genuine Dometic OEM Part: Exact replacement for original equipment, ensuring proper fit and electrical specifications
- High-Temperature Rated: Designed to withstand the extreme heat conditions inside RV rooftop AC units
- Universal Mounting: Standard terminal configuration fits most Dometic rooftop air conditioner models
- Critical AC Component: Essential for proper compressor and fan motor operation in your cooling system
- Direct Replacement: Eliminates guesswork with factory-specified capacitance values
Technical Specifications
| Part Number | 3311563.000 |
| Capacitance Rating | 45/10 MFD (Dual Run) |
| Voltage Rating | 370 VAC |
| Application | Rooftop Air Conditioner - Compressor & Fan Motor |
| Terminal Type | Standard Blade Terminals |

Always verify your existing capacitor's MFD rating before ordering to ensure proper replacement.
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, fan runs but compressor doesn't start, intermittent cooling, or a burning smell from the AC unit. Capacitors can also bulge or leak when failed. Always disconnect power before inspecting electrical components.
Can I use a different MFD rating capacitor?
No. 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.
Is this a start capacitor or run capacitor?
This 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.
Do I need special tools to replace this capacitor?
Basic 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.
