Dometic Duo Therm RV Air Conditioner Hard Start Capacitor

The Dometic Hard Start Capacitor for the Dometic Duo Therm 13,500 BTU and the 15,000 BTU RV Air conditioners will install with ease.

  • This will allow your RV Air conditioners to start without pulling so many amps.
  • With one of these installed, a 2000 Watt Generator has enough power to start and run a 13,500 BTU Dometic Air Conditioner and a 3000 Watt generator has enough power to start and run the 15,000 BTU Dometic Air Conditioner with no problem.
  • We recommend pairing your air conditioner with this capacitor because not only will you be able to buy a smaller generator, but it won't be as hard on your air conditioner trying to start it.

Good Deal ON Hard Start
Got this installed and now I can use my Honda 2000 watt generator. It barely starts it, but it does do it now. The run time doesn't bother it all. Thanks a bunch, I had a hard time finding someone who still carried this.
