If your rv fridge works on gas but not on 110v ac then try this.
Rv fridge not working on ac.
That means if the evaporator coils are clogged with frost it would prevent airs from passing through and reduce the cooling effect of the refrigerator.
Use thermometers designed for use in refrigerators.
If however you set the temperature right and the ac keeps blowing out hot air then it is possible that the problem itself is in the thermostat.

In the case it appears that the coils have too much frost on them you should use a hairdryer to apply hot airs to coils.
If you fail to make the switch as you approach higher altitudes your burners can well burn out.
No ac power to rv check that there is power to the shoreline receptacle.
