Puma ac unit fan running but no ac

[scoremaster]

Have a mbc20 puma this weekend we went camping all was well after we set up turned on the ac like always and fan kicked on and heard ac unit kick in but no cool air just fan checked all breakers fuses and such all were fine so just thought maybe was having a voltage issue so just let fan run when we got home today plugged into home power and still same issue .
Camper is a 2022 puma xlt lite was hoping something simple short of a trip to the dealer as it takes them forever to take care of an issue
Thanks for any advice

Set the thermostat to AUTO.
