Common Causes of Refrigerator Getting Too Cold

Understanding why your refrigerator is freezing food in the fresh food section starts with looking at the most common problem sources. Overcooling can result from simple misadjustments or more complex electrical faults that require professional diagnostics.
Below, we break down the four primary causes so you can better identify what might be wrong with your appliance.

Misadjusted Thermostat

The thermostat is your refrigerator’s first line of defense against extreme temperature fluctuations. If set too low, it can cause the compressor to run longer than necessary, sending too much cold air into the fresh food compartment. Even a small adjustment can make a big difference in maintaining proper temperatures. Many homeowners forget to check the thermostat after cleaning or moving the refrigerator, inadvertently leaving it on a colder setting. Over time, this can lead to frozen vegetables, icy milk, and ruined leftovers. In most cases, adjusting the thermostat to between 35°F and 38°F will resolve the issue. However, if changes to the setting have no effect, the thermostat itself may be defective and require replacement.

Faulty Thermistor

The thermistor works as your refrigerator’s temperature sensor, sending data to the control board so it can regulate cooling cycles. A faulty thermistor can misread the actual temperature, tricking the control system into overcooling the fresh food compartment. This type of malfunction often goes unnoticed until the problem becomes severe. You might see frost forming on items in the fridge, or liquids may start to partially freeze. Testing a thermistor requires a multimeter and knowledge of your refrigerator’s electrical specifications. If readings are inconsistent or outside the normal range, replacing the thermistor with a compatible part is the best solution. At UpFix, we routinely test and replace thermistors to restore accurate temperature control.

Damper Control Issues

The damper control regulates how much cold air from the freezer enters the fridge compartment. When functioning correctly, it opens and closes based on the thermostat’s signals to maintain even cooling. However, if the damper control is stuck open, it will allow too much cold air to flow into the fresh food section. This causes uneven cooling, with items near the vent freezing solid while others remain at an appropriate temperature. Damper control issues can be mechanical, such as a broken flap, or electrical, involving the actuator motor. Diagnosing the problem often requires removing the cover and inspecting for blockages, damage, or malfunctioning components.

Defective Control Board

The control board is the brain of your refrigerator, directing the operation of the thermostat, thermistor, and damper control. If it malfunctions, it can send incorrect commands that result in the refrigerator running too cold. Defective Refrigerator Control Boards may have visible burn marks, damaged wiring, or failed solder joints. In some cases, the failure is subtle and can only be detected through electrical testing. Because control board issues can mimic other component failures, it’s essential to rule out simpler causes before replacing it. At UpFix, we specialize in diagnosing and repairing refrigerator control boards, saving customers from unnecessary full-appliance replacements.

Step-by-Step Troubleshooting for a Refrigerator That’s Too Cold

If your refrigerator is overcooling, a systematic approach to troubleshooting can help pinpoint the exact cause. This ensures you address the root of the problem instead of replacing parts unnecessarily.
Follow these steps to test and correct each potential cause in order of simplicity.

Step 1 – Adjust the Thermostat Setting

Start by setting the thermostat between 35°F and 38°F, which is ideal for most refrigerators. This temperature range helps maintain freshness in perishable food while preventing items from freezing in the fresh food compartment. After making an adjustment, allow at least 24 hours for the temperature to stabilize fully before deciding if further changes are needed. This waiting period ensures that the refrigerator has enough time to respond to the new setting and avoids misjudging its performance. If food continues to freeze despite setting changes, the thermostat may not be functioning correctly. In such cases, replacing it with a compatible unit may be necessary to restore proper cooling levels. Always use a reliable refrigerator thermometer to confirm the accuracy of the temperature setting. Placing the thermometer in various locations inside the refrigerator can help detect uneven cooling, which might indicate other underlying issues. By starting with this simple step, you can often resolve overcooling problems without the need for complex repairs.

Step 2 – Test the Thermistor

Using a multimeter, check the thermistor’s resistance at various known temperatures to ensure it’s within the manufacturer’s specifications. The thermistor plays a key role in sending accurate temperature data to the control board, which in turn regulates the cooling cycle. If the thermistor is giving false readings, the control system might think the refrigerator is warmer than it actually is, causing excessive cooling. Testing requires carefully accessing the thermistor, usually located behind a panel or cover inside the fridge compartment. Take multiple readings at different temperatures to see if the resistance changes in a consistent pattern. If readings are erratic or outside the expected range, the thermistor is faulty and should be replaced promptly. A properly functioning thermistor ensures the control board receives correct data to make efficient cooling decisions. This step is relatively inexpensive but can have a major impact on your refrigerator’s ability to maintain the right temperature. By addressing a faulty thermistor, you can prevent further stress on other cooling components.

Step 3 – Inspect the Damper Control

Remove the damper cover and check if the flap moves freely when temperature changes occur. The damper control regulates the flow of cold air from the freezer to the refrigerator compartment, and if it’s stuck open, too much cold air will enter, freezing food. Mechanical issues such as a broken flap, worn hinges, or debris buildup can obstruct proper movement. Additionally, the actuator motor that operates the damper may fail, causing it to remain in one position. Inspect for visible signs of wear or damage and clear any obstructions that might restrict airflow. Testing the damper’s movement can be done manually or through the refrigerator’s diagnostic mode, if available. If the damper is damaged beyond repair, replacing it will restore proper air distribution. Ensuring that the damper works correctly helps maintain balanced cooling throughout the fresh food compartment. By fixing damper issues early, you can avoid uneven cooling and prevent foods from freezing unnecessarily.

Step 4 – Inspect the Control Board

If the thermostat, thermistor, and damper control are all working correctly, focus your attention on the control board. This component acts as the refrigerator’s brain, processing data from sensors and sending signals to cooling elements. Look for visible damage such as burnt areas, loose connections, or corrosion on the board’s surface. Even minor electrical faults can cause the control board to send incorrect signals that lead to overcooling. Use a multimeter to test the board’s outputs and verify if they align with manufacturer specifications. If anomalies are found, the control board may be malfunctioning and require repair or replacement. UpFix specializes in repairing refrigerator control boards, which can be more cost‑effective than purchasing a brand‑new unit. When the control board functions properly, it ensures all cooling components operate in harmony to maintain the correct temperature. Addressing control board issues is often the final step in resolving persistent overcooling problems and restoring your refrigerator’s optimal performance.
