Our fridge is in the slide and was having cooling issues also. When I opened the top vent to see what was going on the metal aid dam( not sure of technical term) that is supposed to force hot air of of top vent was actually sitting in front of coils forcing the hot air to go in cavity above the ridge. Took the metal out and refitted it behind the coils and now you can feel the heat come out of the top vent. We also ad four ice packs into fridge every eight hours or so when temps get above 90° it that seems to make a big difference. Per wife, next fridge will be residential as she is tired of dealing with warm fridge temps and limited time in keeping it opened. Good luck.
