I saw that box when I had the cover off during one of my "tests" of the unit. Never looked hard at it though. The fact that none of the input or output copper tubes on the compressor are hot or cold, even though the compressor itself gets quite hot, leads me to think there has been a coolant leak. The trailer is going to a local Dometic service outlet on Monday. Hopefully they will diagnose and eventually repair or replace.
Any advice I should give to the service guys? There is no Airstream dealer within 2600 km of here and these guys will have never been in one, much less worked on one. How do they get on the roof without denting it?
