Probably low on freon. You may need to have a tech come and recharge it. This type of ac generally do not have a charge port.

Good thinking... you need to hire a service technician (a good one!). Too many jackasses think they know these systems. Obviously, there's something wrong with the system.. if so, you need someone who knows what they're working on/with.

yes if it has service ports but if it lee=aked out you need to fix leak first

There are a variety of probable causes of your AC's failure to blow cool air. Unfortunately, it is difficult to diagnose your situation without being there. However, I have a great, handy diagnostic article that specifies the main problems so that you can definitely come to find the cause applicable to your AC's failure. I'm not too familiar with RV AC's and how they may differe a bit from house AC's, but your AC very well may need a recharge of refrigerant/Freon by a technician, but short of that, try this first:

This should defintely help.
Good luck!

The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Find thermistor/thermostat that is usually attached by plastic holder at back on one of the fins in fridge compartment. Pull it off, and move it over to left 2 fins, then give 24-48 hrs and see if any change.
