I wish I had found this forum earlier. I had the same issue with my Carrier Central Air. I had to get a tech to come out and look at it. I gave him an explanation of what it was doing(about 30 seconds), he took the side panel off(about 30 seconds), he looked at the upper right where the Capacitor was(about 5 seconds), he says to me "I think that is your problem, the capacitor is swolen". He pulls off the old one(about 30 seconds), puts in a new one, I turn on the unit from inside and Presto.... about 3 minutes and $210.00 later it is running. the sad part is the capacitor was sold to me for $165.00(plus $50.00 for the site visit) but i think i can see capacitors like this for under $30.00. so although i am grateful for his experience, i think sometimes these repair techs want to bleed you. He could have marked it up twice or maybe 3 times, but 5 times is just gouging. So anyways if you have a way to check the capacitor, i would do it.
