7 Common Reasons Why Your Refrigerator Isn’t Cooling

Posted By On 10-08-2022

If you open your refrigerator and find sour milk or warm wine, it should be obvious that your refrigerator is not cooling properly. The issue is more than simply inconvenience and scents; it is also a health hazard. Listeria and other foodborne pathogens, as well as mould, can develop in warm refrigerators.

There is often no need to hurry out and buy a new refrigerator. While some repairs may need the services of an appliance specialist, others are easy and require no special tools or training.

Here are seven simple reasons why your refrigerator isn't chilling and what you can do about it.

Temperature Control Is Improperly Set

The ideal temperature for a refrigerator is between 3 and 5 degrees Celsius. New refrigerators typically come preset at this temperature. However, the thermostat dials inside the fridge can sometimes get bumped, which can change the set temperature.

If your digital thermostat is located in a spot where it can be easily changed, you may want to consider locking the settings. This will prevent anyone from accidentally raising the temperature. If the temperature does get changed, reset it to the safe zone and allow a full day for the temperature to stabilize.

Damaged Refrigerator Compressor

If the refrigerator is not working properly, the compressor may be damaged. To check the condition of the compressor, unplug the refrigerator and remove the access panel. Inspect the compressor coil and the connections. If the coil is blackened or burned, the compressor is damaged and needs to be replaced. Check the connections to ensure that they are tight. If the connections are loose, reconnect them and replace the access panel.

Deterioration of the Rubber Seal

If the rubber seal around the refrigerator door deteriorates, the door will not seal properly, and the refrigerator will not keep food cold. If the seal is deteriorated, replace it with a new one.

Here are more reasons (Food Items Are Blocking the Air Vents, Refrigerator Is Understocked, Inconsistent Power, Damaged Ice Sensor) why your refrigerator isn't cooling.

Food Items Are Blocking the Air Vents

If your refrigerator isn't cooling, one of the first things you should check is whether or not the air vents are blocked. If the air vents are blocked, the air can't circulate properly, and the fridge won't be able to maintain a consistent temperature.

Refrigerator Is Understocked

Another reason why your fridge might not be cooling properly is if it's understocked. If there isn't enough food in the fridge, the air will circulate too freely, and the fridge won't be able to maintain a consistent temperature.

Inconsistent Power

If the power to your fridge is inconsistent, that can also cause the fridge to have trouble maintaining a consistent temperature. This can be caused by several things, including a power outage or a tripped circuit breaker.

Damaged Ice Sensor

If your fridge has an ice sensor, that can also cause the fridge to not cool properly if it's damaged. The ice sensor is responsible for telling the fridge when to turn on and off the cooling cycle, so if it's not working properly, the fridge won't be able to maintain a consistent temperature.


There are several potential reasons why your refrigerator is not cooling. It could be that the fridge is not set to the proper temperature, the door is not sealed properly, the condenser coils are dirty, or there is a problem with the evaporator fan. By troubleshooting each of these potential issues, you should be able to figure out what is causing your fridge to not cool properly.
