Dometic refrigerator icing/frosting very quickly
All of a sudden our dometic fridge in our 25' 2016 flying cloud is icing on the fridge fans and frosting up in the freezer super quickly - within a matter of days of defrosting both fridge/freezer it is iced up again and has significant frost in the freezer.
I have it set on 4 out of 5 - when I set it on 3 it barely stays under 40 degrees.
Set on 4 it is staying at 37/38 so it is cooling. It is not running constantly or anything - just icing up.
We are in SoCal - so it is warm but not hot - 70's during the day and the unit is not in direct sunlight.
Any ideas what might be wrong? I checked the door seals on both and they are all fine - so it isn't outside air getting in. It isn't an issue of shoving too much stuff in the unit - it is full but not overstuffed.
