Frozen lettuce, icy milk and eggs that crack in the carton are a frustrating combination. When a fridge starts freezing food in the fresh food section, the cause is often simple, but sometimes it points to a faulty sensor, damper or control.
Why Is My Fridge Freezing Food? The Short Answer
A fridge usually freezes food because the temperature is set too cold, food is sitting in front of the cold air vent, the air damper between the freezer and fridge is stuck open, or a thermostat, temperature sensor or control board is faulty. A cold room, overloading and a worn door seal that makes the fridge run constantly can also contribute. Check the settings and food placement first. If food keeps freezing, a technician should test the sensor, damper and controls.
Common Causes of a Fridge Freezing Food
1. Temperature set too low
This is the most common cause. Dials can be bumped, and number scales are confusing because on many fridges a higher number means colder. Around 3 to 5 degrees Celsius is a good general target for the fridge section. Check with a thermometer in a glass of water. Our guide on how to reset a fridge thermostat explains how.
2. Food blocking the cold air vent
Cold air often enters the fridge from vents at the back or top. Items pushed against the vent can freeze solid while the rest of the fridge is fine. Move food forward and leave space around the vents.
3. Stuck air damper
Many fridges use a damper to control how much freezer air enters the fridge. If it sticks open, too much cold air flows in and the fridge freezes food. Damper faults need a technician.
4. Faulty thermostat or temperature sensor
If the thermostat or sensor reads warmer than reality, the fridge keeps cooling. Our article on faulty fridge thermostat symptoms explains the signs.
5. Control board fault
On electronic fridges, a faulty control board can keep the compressor running or hold the damper open.
6. Worn door seal
A leaking seal lets warm air in, so the fridge runs longer. In some fridges that means the coldest areas become too cold. Clean seals and do the paper test.
7. Very cold room
In a cold garage or laundry, some fridges behave unusually and may freeze food or let the freezer warm up. See how room temperature affects a fridge.
8. Dirty condenser coils
Dirty coils make the fridge run longer, which can contribute to over-cooling in some designs. Vacuum them with the fridge switched off at the wall.

What You Can Check
- Measure the temperature with a thermometer.
- Adjust the setting one step warmer and wait 24 hours.
- Move food away from the vents.
- Clean and check the door seals.
- Clean the condenser coils.
- Check the room is within the fridge’s climate class.
When to Call a Technician
Book a repair if food still freezes after adjusting the settings, if the temperature does not change when you adjust the control, or if the fridge runs almost constantly. A technician can test the sensor, thermostat, damper and control board. For frost-related problems, see our guide on frost build-up in the freezer.

Frequently Asked Questions
Why is my fridge freezing everything?
Usually the temperature is set too cold, food is blocking the cold air vent, the air damper is stuck open, or a thermostat, sensor or control board is faulty.
What number should my fridge be on?
It depends on the model, as some use higher numbers for colder. Use a thermometer and aim for around 3 to 5 degrees Celsius in the fridge section.
Why is food freezing at the back of my fridge?
The cold air vent is often at the back. Food touching or in front of it can freeze. Move it forward and leave space around the vent.
Can a faulty door seal cause food to freeze?
It can contribute. A leaking seal makes the fridge run longer, which can over-cool the coldest areas.
