Your fridge will only remove a certain amount of heat. As outside temp goes up (say beginning at 90f) your fridge temp will follow. So if your fridge is 45f when its 90f out, it will be around 55f at 100f outside temp. One may argue and say 'mine does this or that at 100f, and that's fine, many things, like shading the coach on the side with the fridge, may affect fridge temps. And, Absorption fridge will take 2 days or more to cool down after being off for the winter. Residential fridges do a much better job of keeping your food at 40f (recommended) and your freezer at 0f (recommended). And a residential fridge installed in your coach exists in an inside, climate controlled environment, thus keeping temps more stable. Since an Absorption fridge works on propane, the whole fridge compartment must be vented, essentially its 'outside' and subject to high ambient temps. Our 4 door Norcold worked as designed, but it never worked as well as the residential fridge that took its place.
