Quick history all.

AC's were running, then back ac quit last week, Fan runs on high and low no problems , compressor wouldn't energize, slight hum. This morning, front ac fan was running, but compressor wouldn't start and a terrible odor, something melted maybe??? Anyway, after I open the windows and ran the fantastic fans a while, I ran both ac's on high and low fan, all was well,. Tried to run the ac's for cooling and heard compressors try to start, followed by a humming, I turned them both off immediately, oh and no breakers tripped and no fuses burned. Any suggestions will help, thanks. I got Rv on a dedicated 30amp / 125vac feed, and excellent line voltage / and amperage protection in the Rv, fed from my 200 amp house panel.

Capacitors!Just about everyone has to replace one during ownership.
The smell was the rubber/plastic capacitor case etc trying to burn.
This has happened a lot over the last decade.
Had a conversation with AC parts warehouse mgr. Home units RV units.
He has those marked made in the USA but are identical to ones marked made in China because they are but cost $10.00 more.
Home units replaced four in to years. So far on RV replaced two. Found old ones, made in the USA in Elkheart Indiana.
We have two new units for home and so far in a year not replaced capacitors. They don't have to be identical to the old ones to work and ones marked with a higher rating will work as long as they have have the required spades. Extras on it don't matter is what he said. ..but they do have to fit need to be held in palace by that clamp or something.
