AC only blowing warm air

[Utahcamper12]

I have a 2006 Kodiak by Skamper. We just bought it and it appears as if the AC does not function correctly. When plugged into my home electric, the AC unit seems to be running fine but the air coming out is room temperature. I have cleaned the filter and took off the outside shroud to inspect the roof unit, both are clean. It seems to be running at full power. I set the temp. dial to it's lowest setting to no avail. It has a 13500 btu unit. If it wasn't receiving enough amperage shouldn't the wall supply socket trip since the unit would try to draw more than was being supplied? Does anyone know what type of refrigerant these AC units use? I know they are sealed units but they can be recharged if a port is added. Any suggestions?

Questions:
What's Make/Model of this A/C?
Is it Ducted (like a central home unit, ducts in ceiling, wall thermostat)?
Or Non-Ducted (blows air only from the unit itself, controls are a switch knob and a thermostat knob)?
Can you SAFELY get up on the roof to do an inspection?
DISCONNECT POWER FIRST
Take the plastic cover and some of the internal sheet metal off?
Take and post a couple pictures?
Info:
Yes, it's possible to add a service port, evacuate, re-charge, etc. Usually doesn't work well because of labor cost, trying to find/fix the leak, difficulty of getting the EXACT right charge in it.
Used to use R-22 but have changed as of late.
If it's a Coleman, label on front left side of the sheet metal should tell you.
It uses at least two capacitors.
One is Fan Run, and apparently Fan and Cap are OK since it's moving air.
Other is Compressor Run. Could easily be bad if compressor isn't running.
The two capacitors could be in a common (dual) unit.
MIGHT have a Start Assist Capacitor also.
For Compressor to run, the Run Cap and the Start Assist both have to be good.
If you don't have a Start Assist, the Run Cap must be good.
Run Cap(s) usually metal cases. Start usually plastic case.
Pix we'd like to see: Label/Wiring Diagram, AND Capacitors.
See what you can do and report back.

Fan comes on so AC Unit is getting signal from t-stat.

Does the compressor turn on?

No compressor....no cold air. Start capacitor, bad wiring, bad compressor motor


Compressor turns ON..no cold air cause no coolant. Replace A/C Unit

got the thrmostat set to coo? and some times they hesitate for a minute before the compressor kicks on, if theres a battery in the stat change t, get a helper one to turn it on the other on the roof to listen for the compressor to come on. its 15teen years old bet it died,

Is the compressor coming on or just the fan?
