Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

If the unit does not cool any better on AC or Propane then likely you have a cooling unit failure. The "coolant" goes to the freezer first, then the refrigerator, so compromised cooling capacity affects the refrigerator first.

Start by making sure cooling capacity is maximized:
1. Defrost if more than 1/4" of ice.
2. Do the "dollar bill test" to verify that the door seals are snug.
3. Insure that the restrictor is in the bottom/outside end of the condensate drain.
4. Check that air flow in the bottom and out the top of the outside refrigerator area is unobstructed.
5. Particularly if the upper refrigerator outside vent is in the side vs roof, make sure there is no "dead space" above the refrigerator that can accumulate heat.
6. Do the burner area tune-up as outlined in your Dometic manual. Even a slight decrease in flame size can have a detrimental affect on cooling performance.
7. Lastly, use a manometer to verify propane pressure.
