duo therm issue

Thanks for all the assistance on this issue. I replaced the starter capacitor and found that the old starter capacitor had burnt a hole in the run capacitor. I then had to purchase a new run capacitor. Total purchase of 2 capacitors was $45. Everything was hooked backed up today and Air is working great. Planning on a trip to Lakewood campground in Myrtle Beach on July 7 to really give the air a workout. This is our first time at this campground. Hopefully, I will have an event free vacation.

It will be fine. The small black item on top is a PTCR device, which works by getting hot (it conducts power until it heats up, which it does in a fraction of a second) The replacement will have a heavier duty PTCR installed.

Would it have damaged the run capacitor or compressor?

One of the terminals was loose.

pic of capacitorLooks like I was lucky there wasn't a fire the small capacitor is burnt up pretty good and wires melted to terminal. Any ideas what would cause this? I would guess compressor is still ok. Plan on replacing both capacitors.

I just got off the roof and removed the cover of the ac unit. I did not see anything that looked like a cylinder capacitor. I see the compressor and a small tank cylinder beside compressor. There is a metal box where electrical wires come out. Is this were capacitors are found? The unit is on a 2007 cedar creek.

My first thought is the start capacitor shorted.

I would agree, check the start capacitor. It will probably smell burned. If not that, the compressor may be bad.
