Why are fridge questions so popular?!!
I have searched the internet and this forum for an answer, and I am really more puzzled now than before.
I have read much about how RV fridges don't work well in cold weather, along with some of the ideas for fixing the problem, but everything I read has to do with pretty cold temps, usually close to zero or below.
Just went through a couple days of cold weather; mid 20's at night, 30-40 during day, plus wind chill.
So I get up this morning and look to find some things in the freezer compartment to be nearly completely thawed, and most everything in the fridge compartment to be warm to the point of being unsafe. Thermometers show temps to be in the unsafe zone for both compartments, so I ended up tossing some food that just didn't seem safe to keep.
So here is the problem (or two).
When the outdoor temp drops below freezing, (32, give or take) the fridge just shuts down. It doesn't work less efficiently, it just won't come on. No burner burning, no warm coils, etc.. But as soon as the outside temperature rises above freezing (give or take a few degrees), it starts working. Actually, the hotter it is outside, the colder the food, because then it runs constantly.
It's almost as if the thermostat for the fridge is located outside the box, so it is only activated by the outside temp, not what's going on inside the fridge! Along those lines, Dometic told me some time ago when I asked about another issue that it was probably installed incorrectly; in their opinion bad installs happen frequently. I noticed that there is an inch to two inches of space around the box (top and sides), so I considered that maybe the entire box is affected by the outside temp because it isn't insulated enough, thus confusing the system. Should there be any space around the top and sides?
