SOURCE: will not shut off
Sounds like a stuck relay on the unit itself. Maybe there is a short in the control wire that comes from the thermostat that activates the fan.
The thermostat probably has one hot wire at all times. The thermostat then chooses which wire to send the voltage down based on your selection. One of those wires is probably for the fan only. Make sure that it is in good condition (no bare, pinched or wires)

you have to run a contractor grade extension cord(10-12 gauge) from your rv to run those or theyll do that, the lower the gauge the better, best bet is to plug the rv directly into the outlet, if you cant, get the shortest and thickest extension cord you can.

If the compressor is running with no cold air the unit is more than likely no good. It can not be recharged. you need a new unit. If the compressor is not running you need to check the capacitors.

check the compressor winding resistance from common to start
start to run
run to common
the two lowest should equil the highest
also check shorted to ground
check the capacitors the go bad a lot
