The capacitor is a one condition item. If it's bad it will not work at all. If it works, it's not bad.

I had the same symptom as did Ron. when the capacitor fried I had a strong odor of burning insulation and a loud hum from the AC compressor. Continuing to try and run the AC will likely result in a fire in those conditions. Replacing the capacitor is not a big deal and there is little you have to remove under the cover. My tech has gone though the route with Dometic many times. He found that the Coleman AC units used a residential grade capacitor that is more robust. Dometic seems to have agreed as their new replacement units look identical to the Coleman ones. I went through 2 capacitors on my main AC / heat pump unit before going to the larger capacitor. It's been 3 years now with no problems from it.

You need the capacitor to send the big voltage spike to get the compressor turning as it takes a huge amount of juice to start. Once running it's fine.
