Fixing a Mini Fridge That Isn't Cooling Properly
A mini fridge is practical and convenient for those who do not have access to a larger refrigerator. But like all other mechanical appliances, they can experience problems and require attention. If you've noticed your mini-fridge isn't cooling as it should be, following these 7 tips can help keep your mini fridge running at optimal temperatures and efficiency.
1. Keep out of the Sun and Away from Heat Sources
It is important to place your mini fridge away from direct sunlight and heat-producing appliances such as TVs, microwaves, and ovens. An ideal spot would be in a dark corner of a room, away from windows and other appliances. Sunlight and heat can cause the inside of a mini-fridge to become too warm and make it run inefficiently.
2. Choose the Right Floor Surface
Carpets, rugs, and other materials that hold heat can prevent your mini fridge from cooling as it should. The best surface to place it on is a cool, hard floor such as tile, concrete, or linoleum. If carpet is your only option, try placing something between the mini fridge and the floor for insulation.

3. Clean Underneath It
Heat will be trapped underneath your mini fridge if there is clutter and dust build-up. Therefore, it is important to clean underneath it often to ensure it has proper air circulation. Use a vacuum cleaner or other cleaning tools to ensure dirt and dust are removed regularly.
4. Give It Room to Breathe
A mini fridge needs adequate space in order to properly disperse heat. Refrain from crowding it with furniture or leaving it blocked in tight spots. Keep enough distance around it for air to circulate and provide better cooling performance.
5. Store Cool Items
If possible, store items such as ice cubes and cold drinks inside the mini fridge to help cool it down. If you need to store hot food, wait until it cools off before putting it in the fridge.
6. Check Door Gaskets
Door gaskets are important because they ensure a tight seal between the door and the fridge, preventing cold air from escaping. If the door gaskets are weak or showing signs of wear, replace them with a new one.
7. Don't Overfill It
Carefully consider how much food you need to put in your mini-fridge when shopping for groceries. Overfilling blocks airflow, which will prevent the fridge from cooling properly.
Making these simple changes to your mini fridge can help ensure it is running as efficiently and effectively as possible. Additionally, this website has plenty of useful projects and articles about refrigerators and other home appliances. Keep browsing our blog for more helpful information.
Expert Tip:
Be sure to clean and replace the condenser coils on your mini fridge on a regular basis. This will help to maintain a constant temperature and ensure that your mini-fridge operates efficiently.
8. Inspect the Ventilation Holes
Check the ventilation holes at the back of the mini fridge to see if they are blocked. Clean these holes with a pipe cleaner or a vacuum to ensure air is able to flow freely, helping it to cool down effectively.
9. Keep Doors Open for Short Time Periods
Opening the door for extended periods of time will cause cold air to escape and warm air to enter. To avoid this, keep the door open for only short amounts of time, such as when taking items out and putting them in the fridge.
10. Use an External Thermometer
If your mini fridge does not have a built-in thermometer, consider purchasing a stand-alone thermometer. This way, you can monitor the temperature inside the mini fridge and make sure it's an ideal cooling environment.
11. Do Not Put Warmer Drinks in the Fridge
Take temperatures into account when deciding what to put inside your mini fridge. Warm drinks should stay outside until they cool off, as adding them to the refrigerator will raise the overall internal temperature.
12. Avoid Frequent Temperature Changes
The refrigeration system of a mini fridge works best when it is not frequently changed. If the temperature needs to be adjusted, do so slowly to avoid overloading the system.
13. Ensure Proper Voltage Supply
Make sure the plug connecting the appliance is not defective and has the correct voltage supply. If in doubt, consult with an electrician for assistance.
14. Clean Inside the Fridge
Just like cleaning underneath, it is important to clean inside the mini fridge regularly, too. Remove expired food and clean shelves and drawers with warm soapy water or a cleaning solution.
15. Manage Humidity Levels
Keeping relative humidity levels inside the mini fridge between 40-50% helps it to cool properly. If the fridge is in a humid environment, use a dehumidifier or install an extractor fan to reduce moisture levels.
16. Have an Expert Check It
If you follow these tips and your mini fridge still won't cool, it could be an issue with the compressor or other internal components. Have a professional examine your appliance to help identify the exact problem and provide appropriate repairs.
