brand new AC dosent work

[Rammer]

The AC does not work on my brand new unit. Starts up fine but never kicks down into a normal run so the generator overpowers or when I am plugged in it instantly blows the breaker. Anyone else have this problem before?

If you're plugged into a normal 15 amp household circuit, no it probably won't work and will trip the breaker. We have a separate 30 amp outlet and breaker that we use when we have the trailer at home.

Are the problems when your only on a geny and what size? If the voltage is below 103 the compressor will not run.

I have a 3000SEI yamaha. The AC also will not run when connected to a building. It blew a 15AMP breaker in seconds

Won't run/start on a 15 amp circuit, it takes a 20 amp because of the start surge.

If you were told that it would run on a 15 amp circuit they told you wrong.

This is from the Coleman Spec sheet:

Use time delay fuse or circuit breaker (U.L. H.A.C.R. Type C.S.A.) Rated at 20 amps.
Supply wires 12 AWG Min. (Copper)

You should be plugged into the 30 amp outlet on your generator. This will provide 25 or so continuous amps and more than enough for the a/c. On my Honda 3000 I needed a special RV adapter to from RV plug to geny plug.

I've found 20a min to run the AC.

Yes and no.My ac on my new trailer doesn't work.I run it hooked up to my 2 Honda eu2000i's in parallel.The idle on the gens kicks up slightly when I turn fan on but dosnt idle any higher when placed in cool.Also never hear a deep hum from the compressior kicking on nor does the air from the vents get and colder.

With shore power disconnected I can here the 12 volt relays clicking when I work the thermostat.Im thinking the control box in the ac may be bad.Im taking it in on the 6th to have the entry door replaced I'll have them look at it then.

If its a brand new unit,Than call the dealer that sold it to you,as stated by some post here,just verify that your supply power is correct ....

Could be as simple as a loose connection behind the thermostat. They use wire nuts and one may not have been connected right. Did it work when you did your PDI?

I think it did but I was about 60 degrees out when we did the pdi.

They only ran it for a few seconds during PDI. I am using the 30amp attachment on the Genny but it still overloads the generator. It almost seems like the AC never kicks down when it starts. I have it booked in for this week and we will see.
