How to fix it
Work through these in order, the most common causes come first.
Diagnosing Your Specific Problem
Everything in the fridge is too cold, not just one spot: the thermostat is likely set too cold overall.
Lower it incrementally and recheck after several hours.
Only items against the back wall or top shelf freeze: a placement issue, not a thermostat issue.
Keep sensitive items away from the coldest zone rather than adjusting the whole unit's setting.
Freezing started after adjusting a separate freezer compartment: check whether that adjustment is diverting more cold air into the ma in compartment than intended.

FAQ
Common questions
Why does my mini fridge freeze drinks and food that aren't in the freezer section?
The most common cause is a thermostat set too cold combined with a single-sensor cooling system. Many mini fridges use one thermostat sensor to control cooling for the entire unit, so a setting that keeps a small built-in freezer compartment cold enough can push the ma in compartment below freezing, especially in models without independent zone control.
Are items near the back of a mini fridge more likely to freeze?
The cooling element or vent is usually located at the back or top of the compartment, so that area runs coldest. Items placed directly against the back wall or directly under the cooling vent are the most likely to freeze first, even when the rest of the compartment reads a normal, safe temperature.
Does the type of mini fridge affect how likely it is to over-freeze?
Basic compressor mini fridges with a single thermostat and no separate freezer compartment are the most prone to over-freezing the ma in space, since there's no independent way to keep the whole unit colder without affecting everything inside. Models with a small internal freezer box and separate airflow control, and thermoelectric mini fridges in general, are less prone to this specific problem.
Is it safe to eat food that accidentally froze in the fridge section?
For most solid foods, yes, it's safe, though the texture may suffer, particularly with produce, dairy, and anything with high water content that can turn mushy or separate after thawing. Glass bottles and cans are the bigger concern, since freezing liquid expands and can crack glass or cause a can to burst. Remove any glass or sealed liquid containers from the coldest zones once you've identified w here over-freezing happens.
