Strange phenomena in fridge.

[F Murtz]

If I leave an open drink on the top shelf of my fridge (non freezer
section)without changing temp settings, on hot days the drink freezes.

I can only think that the thermostat must be sensing part external
ambient temp and compensating, which does not say much for design.

Or is it that your fridge is not "fan-forced" (to distribute the cold
around the chamber) and the drink is right next to the cooling element?

If the entire chamber was capable of freezing a drink wouldn't
everything else be frozen too?

Heat enters the fridge from all over, but the fridge is cooled at the
top. When the temperature outside is higher, more heat flows in, so to
maintain a steady state inside the fridge, more heat must be pumped out.
The flow of air in the fridge is obstructed, both by the things in the
fridge, and the turbulent flow of the air itself, so that represents a
thermal resistance. The greater the amount of heat flowing through a
thermal resistance the greater the temperature gradient. So, with a rise
in outside temperature, some parts of the fridge get warmer, and other
parts get colder, as you've discovered.

Open the fridge and look at the back. Mine has openings where cold air
enters the fridge cavity.

If I put things a the back next to these inlets they get frozen.

No only the drink on the top shelf in front of what looks like a closed
in box with the words active smart on it which could be a fan (it has
small vent under it.
This freezing phenomena only occurs in hot weather

When I get a tuit I may investigate further and get workshop manual for
a looksee and get a couple of thermometers and investigate but for the
moment it is just interesting.
