2020 Airstream Atlas

[Island Girl]

Has anyone had a problem with the Atlas thermostat changing temp? I have it set to cool 72 on auto. Works great. However, every now and then, it will read the inside temp at 20 or 64 or 68. It SEEMS that it does this when I come in from the outside or, if I was cooking something on the stove, and have the vent open, when I close the vent, it goes wonky. Then, maybe 10-15 minutes later, it goes back up to the real inside temperature and everything works fine again. ???
