Turbs is closest to what my problem "may" have been. I ended up taking it to the dealer, and they said there were areas of air leaking back and forth. I think this plus a combination of me running the ac on low when it was Uber-humid caused my problem. Time will only tell.

It's probably not going to get a real test until next warranty no less, wish me luck

A/C freezing up is usually caused by 1 of 2 things. Insufficient airflow across the evaporator or low refrigerant.

Freeze up is not normal. You have low coolant gas. And...SOME Dometic units do have a port for recharging. (I don't know about others) The issue is why do you have low coolant? There must be a leak because it does not evaporate on its own. They do make a sealer for RV units, but it is very very expensive.....But it will work to seal any pinholes you may have. If you are under warranty take it in now.

Good Luck!

You don't necessarily have to have low refrigerant in these units to have them freeze up. It's very easy to get these units to freeze up by affecting the air flow through them or increasing the humidity to the point that the unit can't shed it from the evaporator coils. That's why they have freeze coils on them. Because the mfg's know that it's going to happen.
