roof air failures
In just the last 3 months 7 of my friends have their roof air units fail. 4 of the RV's were new. Has there been a design change? Have any of you seen a similar situation? Seems weird to me.

Dometic can have a poorly soldered board. I had 3 new units installed on my 12 year old RV last year. When the last one went in, there were 12v issues, the unit was slow to turn on, and sometimes would not turn on.
The Tech came back and did a visual inspection of the board and found that some of the components were not fully soldered in to the circuit board. He replaced it and the issues are gone.
I worked as a manufacturing eng for 10 years, and even in the best soldering machines you can have fluctuations in the solder wave as boards flow over it. This causes cold solder joints and lack of a complete solder joint. It happens. And several hundred boards can be made before it is discovered.
