Usually it can be a broken capacitor that stops your ac unit from blowing cold air and lets it blow warm air instead.
Rv ac system not cooling.

There can be issues with the thermostat or the capacitor in the air conditioner.
As already stated the non ducted system simply blows air into your rv from its central roof top location.
Also a duct system is easily modified if there are cooling problems.
Unless you have two ac units.
There are several potential causes for the ac not keeping the air cool in your rv.
It could simply be too hot outside for your ac to keep up.
Once the temperature was 76 degrees the compressor on the ac would stop running.
The fan would still run but it was no longer cooling the air.
The two most common complaints are not cooling and leaks.
One can face varying issues with camper ac s like the rv ac shuts off on its own or the ac turns on and off repeatedly or sometimes the ac wont blow cold air at all.
The ac unit could be old.
Rv air conditioner non ducted.
Pulling the handle stops the air conditioner from using the ducts and just blows the air out like a non duct system.
