Something wrong with your thermostat, but if you are using a electronic thermostat and have the indication of supply like light in your control then you can replace the miniature relay that triggers the cool mode of the unit. But no indication of supply try to check the fuse, then if not works you to replace new thermostat.

It is a closed system, (ends are soldered) that said, a heating and cooling guy may be able to install fill valves and re-charge for you, but make sure you get a quote ahead of time. How old is the unit? Not normal for them to need re-charge, and I've seen them work good for 15 years, if maintained properly. Has it been completely cleaned recently?

If the Air comeing out is the same as the temp inside the RV make sure the compressor is running and not just the fans. It could be low on freon. If freon is ok then you would need to ck the wiring to the selector switch for a short. It would be obviouse because there will be melted wires. I am leaning toword low on freon since you have already been inside the wiring/control unit.
