2020 Pinnacle 36SSWS - Main A/C not cold

Hi! Brand new unit....2nd problem with this new Pinnacle on our first trip :(

Main A/C was working fine on Thursday into Friday morning. Last night and now, air isn't coming out cold. 2nd A/C is working fine...thank goodness because I need it cool when sleeping.

Any thoughts???

Thanks in advance.

    If after it sets for a while and starts blowing cold again, back off the temp a little from max to see if that helps to keep it from freezing up. I have to do that on mine

    If you had the fan on low the evaporator possibly froze up. Turn it off for an hour or so and then run it only with the fan on high. If it starts to cool then leave the fan on high for the whole time it's running.
