New RV Rooftop Air Conditioner Capacitors

Repair or service your RV cooling system with RV air conditioner capacitors for compatible rooftop A/C units in motorhomes, fifth wheels, campers, and travel trailers. This collection features brand-new replacement A/C capacitors for systems from manufacturers including Coleman-Mach and Dometic.

Capacitors are electrical components used within rooftop air-conditioning systems to support the operation of components such as the compressor and fan motor, depending on the specific A/C design. Because capacitor specifications vary between air conditioner models, selecting the correct replacement requires more than simply matching the physical size or appearance of the original component.

RV A/C Start & Run Capacitors

Products in this collection include:

• RV air conditioner capacitors
• A/C start capacitors
• A/C run capacitors
• Replacement rooftop air conditioner capacitors
• Capacitors for compatible Coleman-Mach and Dometic A/C systems

When selecting a replacement RV A/C capacitor, compare the capacitance rating (µF), voltage rating, capacitor type, terminal configuration, manufacturer part number, and stated air conditioner compatibility provided in the individual product listing.

The complete air conditioner manufacturer and model number should also be identified before ordering. Coleman-Mach, Dometic, and other rooftop A/C systems can use different capacitors across model families and production revisions.

A capacitor that looks identical to the original may have different electrical specifications and should not be considered interchangeable based on appearance alone. Where available, cross-reference the original capacitor or OEM part number with the replacement product and verify its electrical ratings.

Because capacitors are electrical service components, diagnosis and replacement should follow the air conditioner manufacturer's service procedures and appropriate electrical safety practices.
