Dometic Dual Run Capacitor for RV Air Conditioners

The Dometic dual run capacitor is a replacement motor run capacitor for Dometic RV rooftop air conditioners. It is also called an AC capacitor or dual run capacitor. It supports the compressor and fan motor so the system starts and runs smoothly. Selecting the correct MFD rating for your unit helps the air conditioner perform reliably in hot weather.

Key Features:

• Dual capacitor design serves both the compressor and the fan motor in one component
• Helps provide steady motor start-up and efficient running performance
• Built for the vibration and temperature changes common in RV rooftop air conditioning systems
• Direct replacement for a worn or failed capacitor
• Available in multiple MFD ratings to match different air conditioner models

A failing capacitor can cause hard starting, humming, weak cooling, or an air conditioner that will not start. Replacing it with a Dometic capacitor restores normal operation. Always disconnect all power and discharge the capacitor before servicing. Choose the variant whose MFD rating and terminal configuration match your unit's original capacitor.
