fridge cooling problem Dometic DM2852
Having a cooling problem with my fifth wheel fridge. 2011 Crossroads Cruiser Sahara. Since day one cooling has only been adequate. I had it check right after we bought it and was told working fine no problem. Our last outing cooling was great, outside temps were only in the 80’s. On the way home stopping half way for a quick lunch the fridge temp was 52 deg. I took it back in to the same dealer and they say I need a new fridge. #@%!’ers. Cooling unit out. I have been monitoring it over the last few days and my results are below

75 Outside temp 2:00PM fridge 33 deg fins 24
One hour after switching back to controlled electric
75 Outside temp 6:00PM fridge 43 deg fins 38
Electric heat element check
Outlet was pushing 124V. Amp rate on the heating element was 2.68A
2.68A X 124V = 332W
+/- 10% (33) = 365W element seems to check out!
Gas is just as bad, so I’m kind of think control board since when bypassed temps dropped to freezing.
Am I missing anything? Any help would greatly be appreciated!
