When lettuce turns to ice and milk slushes up in the fresh-food side, the fridge is running too cold for that compartment. Sometimes it's a simple setting or where you've put the food; sometimes a part that controls airflow or reads the temperature has failed. Here's how a tech narrows it down, and what's safe to try first.
It sounds obvious, but a bumped dial or a setting change is the most common cause. The fresh-food section should sit around 37°F; set colder than that and items near the vents freeze.
Check it: Set the fridge to about 37°F (freezer 0°F) and give it 24 hours. Put a cup of water with a thermometer on the middle shelf to confirm.
Cold air enters the fresh-food section through vents (usually along the back or top). Items pushed against those vents get blasted with freezing air and ice up, while the rest of the fridge is fine.
Check it: Pull food a couple inches off the back wall and away from the vents, and don't overpack — air needs to circulate.
The damper is a small door that regulates how much freezer air flows into the fridge section. If it sticks open, too much cold air pours in and freezes your food.
Check it: You can sometimes hear/see the damper (often behind a panel in the fresh-food compartment), but a stuck or broken damper is a tech repair.
The control board reads a thermistor to know when to stop cooling. If that sensor misreads the fridge as too warm, the board keeps cooling and everything freezes.
Check it: No safe DIY test — a tech checks the thermistor and control board and replaces the failed part.
A weak door gasket lets humid room air in, which the fridge fights by running colder and longer — sometimes cold enough to freeze the items nearest the airflow.
Check it: Check the gasket for gaps or a poor seal (a dollar bill should drag when closed in the door). A worn gasket is an affordable replacement.
Almost always repair — a damper, thermistor, or gasket is an affordable part, far cheaper than a new refrigerator. Replacement only enters the picture on an old unit with a failing sealed system on top of the freezing issue.

If it freezes even when set warm, the problem isn't the setting — it's usually a stuck air damper pouring in freezer air, or a failed thermistor telling the board to keep cooling. Both are tech repairs.
About 37°F for the fresh-food section and 0°F for the freezer. Colder than 37°F in the fridge and items near the vents will start to freeze. Use a cup of water and a thermometer to check the real temperature.
Often it's a free fix (setting or food placement) or an affordable part like a damper or thermistor. Your $50 Quick Check credits toward the repair if a part is needed.
