a/c questions

92 34' excella with what appears to be original a/c dometic Penquin 15k btu. unit running for the first time on 30amp connection.

Wanted some input before taking for service from those who have way more experience with these units.

Appears to blow/run correctly for the first night but now that the sun is up it appears to be having issues. Unit will shut down/off completely, then start up and blow cold after the 2min delay... but shut down soon after. Ran great last night, but now with the sun hitting it its not so great.

Are we expecting too much from a 20 year old ac? TT was well cared for from what we have seen after spending a week cleaning and figuring out how everything works. No service records unfortunately.

Could be compressor overload or thermal overload. Without doing accurate measurements of the amp draw at the time of shut-down, it's a crap shoot.

You may also have low voltage at the campground in the morning and not at night. Do you have a volt meter?

That's what I was going to ask about... we had a situation in a campground where the campground was "overloaded" because so many folks were using their ACs ... causing a low voltage situation... (The camp host gave us permission to use our Hondas in lieu of their electricity...that was a first!)
