Frequently Asked Questions About RV Air Conditioner Capacitors
What does a capacitor do in an RV air conditioner?
Capacitors store and release electrical energy to help your RV air conditioner start and run smoothly. Start capacitors give the compressor a boost on startup, while run capacitors keep it operating efficiently.
How can I tell if my RV AC capacitor is failing?
Signs of a bad capacitor include a humming sound from the AC unit, warm air blowing instead of cool, or the unit not turning on at all. A bulging or leaking capacitor is also a clear visual indicator of failure.
Are Dometic and Coleman capacitors interchangeable?
No, you should not interchange capacitors between brands unless their specifications—like microfarads (MFD) and voltage—are exactly the same. Always match the replacement capacitor with the original part’s ratings.
Can I install an RV AC capacitor or hard start kit myself?
If you're familiar with RV electrical systems and take safety precautions, yes, installation is possible. However, due to the risk of electric shock, many RV owners prefer to have these components professionally installed.
Which capacitor size do I need for my RV air conditioner?
The correct size (in microfarads) is printed on the side of the old capacitor. Using an incorrect size can damage your AC unit, so always match MFD and voltage exactly, or consult your RV or AC model manual.
