Resadential refrigerator is just like your sticks & bricks refer. I have Samsung RF18 in our MH, works great. Never had melted ice nor warm temps in box. Was your inverter on. Could be problem with the refrigerator, should always run even in low temps.

They all have operating different parameters, usually listed in the owners manual. We didn't do it on purpose, but we lucked into one that operates from 10 to 110 degrees F. I blocked off the outside vent so we don't need it to operate in that range, but its nice to know it can.

The side and upper vents should have been sealed and insulated.
It was installed incorrectly.
Easy fix.

Just cover it up inside.

Cool/heat going in out.

I have a refrigerator and a chest freezer in my garage at the sticks and bricks. It gets down into the low 50's out there and have never had an issue with either.

make sure both side and top vents are blocked and insulated. I used spray foam on top vent and 2 inch foam on side vent with openings taped with that aluminum duct tape. Your home fridge is not vented to the outside so neither should your rv fridge be either.

Block off or seal (leaving a good air space between the back of the fridge to the material sealing off the existing propane outside vent)
note! don't forget to put a small "trap door" so you can remove the old metal outside vent and reach in to turn off the water line to the ice maker..(don't ask)

One more thing to consider. Sometimes refer's just go bad for one reason or another.

You should not have the fridge back exposed to outside temperatures, so seal up those sidewall vents and problem will go away. Your residential fridge is designed to cool itself and evaporate condensation by circulating air underneath, up the back, and out again into the interior over the top.

Light bulb

I will run a light bulb (old fashioned non LED) in the outside compartment..no problems. If real cold, I cover some of the outside vents

I have a similar problem, but not to the extent you do. The colder the outside temp, the warmer the refrig/freezer runs. Looking at the "fine print" for my refrig, it says it is not suitable for placement in a garage...thus I deduce the issue is in the design of the refrig, and it is best to seal up all of the exterior vents to reduce the inflow of cool air.

Unheated Beer Fridge Up North...

My 20+ year old "beer fridge" in the unheated garage in WI starts to have problems controlling freezer temperature when the garage gets around 40F. The fridge will maintain 33 to 40F until the garage temperature get below 25 to 30 and then you better bring inside anything that just has water in it as it will get slushy or worse. Anything with a little alcohol in it seems to not freeze unless it gets below 0F in the garage. This weekend after it finally started warmed up above freezing, the fridge started holding 34 to 39 again even though the freezer was up to 42F! During the summer, the freezer and fridge control to about +/- 1F around setpoint.

I would follow the earlier advice given to block the vents that were needed by the replaced absorption fridge. Your installer either didn't know that unblocked vents can cause problems or he thought you are a fair weather camper that stays home when it's cold.
