Dan is asking good questions,
I have one more question...is is the refrigerator
working best on gas or electric?
In the Scamps and the Burros I have had to use a .25 amp computer fan to boost the performance but not under the temps your in.
Also when leveling the trailer
you are really
leveling the refrigerator
Do not bubble the coach, bubble the fridge
...Also try all the three axis points, the really important one is door to back...I have found that the refrigerator
has been installed so pathetically that on some refrigerators its knocking them out...Since the tech in this fridge
you have is dual carb its supposed to be more forgiving...Norecold more than Dometic.
My gut tells me here we need more info, do not rip it out unless your going to test it...a good test is to remove the sucker and place on a known level surface...with the back wide open run on gas or electric and test its operation...if it runs well the gremlin is in the install.
Any performance test on these absorption units should be a minimum of 6 hours
Happy Camping Safe Trails.
