Hi all,
Just getting ready to leave for the fall convention and discovered my Dometic 2652 fridge is not cooling .
the freezer seems to be feeezing however the lower section is 55'.
Has anyone had the same issue?
Thanks in advance,

Not sure what fridge you have but we have an all electric and the freezer was warking but the fridge wasnt . in ours there is a fan that circulates cold air from the freezer section to the fridge bottom section this fan was not working maybe check if you have a similar setup

Bob, assuming your rig is perfectly level for this exercise and you have also properly cleaned: (i) the burner orifice (which is a synthetic ruby BTW), (ii) the burner and (iii) the chimney all well, the chimney baffle is intact and not rusted away, and nothing changed in the venting of your frig like debris in the upper vent, try this progression:
1. If you haven't already, run it on AC shore power, not propane. Wait a day and then check your frig temp. If it works on AC, you've got an issue with your burner or venting. The baffles can rust away and prevent the burner heat from heating the Ammonia solution enough.
2. If AC doesn't cool the frig, unplug the thermistor from the control board (the thermistor on a Dometic is the wire clipped on a plastic clip on the rightmost cooling fin in the frig compartment). Run the frig on 120 V AC and see if the frig cools, if so, your thermistor is likely bad. There are aftermarket thermistors that are adjustable knobs and not the imprecise slider Dometic supplies or you can just replace it.
3. If #'s 1 and 2 above don't solve the problem, you may need a new cooling unit.
4. Rebuilt cooling units for your model are about $450 versus over $2,500 for a new frig. There are YouTube videos on how to R&R the cooling unit, it isn't difficult.
5. Several Amish companies make new or rebuilt cooling units and these companies are reputed to make superior units but I do not have any personal experience.
I had exactly the same problem with my Dometic several weeks ago and found that cleaning everything and replacing the thermistor did it for me. Before, I couldn't get the frig below 45 or 50, afterwards, minus 10!
