Hey, thanks for all the replies...... FR had failed to install the proper baffling as specified by Dometic. Well, they probably installed it according to Dometics instructions, but Dometic issued a service bulletin later.
However, the REAL problem seems to have been a "bubble" inside the tubing that carries all the coolant around thru the refrig.
The tech tapped it with a hammer a few times and dislodged the bubble. He explained that it's similar to having a bodily artery plugged by cholesterol. So, I guess the unit had a heart attack?
Anyhow, it's working fine now.
