Content Summary
A mini fridge is one of the most used appliances. When it stops cooling, it can be frustrating and even costly if you need to replace it. In this guide, we'll take you through the steps on how to troubleshoot and fix an "un-cool" small fridge. Read on!
Step 1: Check The Power Supply
The first thing you want to do is to check the power supply.
- Make sure the power cord is plugged in and that the outlet is working.
- An electrical surge or power outage may have caused it to trip, which could be a simple fix.
- Check if the power socket is working smoothly by plugging another appliance into the outlet.
Step 2: Check The Location
Other appliances' heat may negatively affect its cooling power.
- When an appliance (oven, dishwasher, microwave, washing machine, dryer) is situated too close to the fridge, it can effect the fridge's cooling performance.
- Create at least 2 inches of space between the appliances for ventilation.
Step 3: Check The Freezer
Check if its door closes properly, and if ice and frost have been accumulating inside.
- In case your fridge has a freezer, the last defrost may have been many months ago. Then defrost your fridge (see our instructions on how to defrost a mini fridge).
- If this doesn't handle the malfunction, try the next step.
Step 4: Check The Thermostat
Then check to see if your fridge’s thermostat is set to the recommended temperature.
- If it is set too high or too low, this may cause it to not cool properly.
- Most times, the thermostat setting might have been lowered unknowingly.
- The optimal temperature range for a mini fridge is between 34°-40°F.
- If your thermostat is set within this temperature range and your mini fridge is still not cooling, move on to the next step.
Step 5: Check The Compressor
If, after adjusting the thermostat, the fridge still isn't cooling, check the compressor.
- The compressor circulates the refrigerant to cool the fridge.
- A problem with the compressor may cause it to stop cooling.
- Call a professional to check the compressor and replace faulty parts.
Step 6: Clean The Coils
When you have confirmed that there is power and your mini fridge is still not cooling properly, check the back of the unit.
- The coils collect dust and dirt over time which can affect the cooling performance.
- Clean them by using a vacuum or brush, and coil cleaner. Read our related guide on how to clean the mini fridge inside out.
- After cleaning, make sure it is two inches from the wall to ensure proper air circulation.
Step 7: Check The Door Seal
If your mini fridge is not closing properly, the cold air will leak out.
- Check the door seal by placing a piece of paper between the door and the fridge, closing the door, and trying to pull out the paper.
- If the paper comes out easily, your door seal likely needs to be replaced.
- You can purchase a replacement door seal online or at your local hardware store.
Step 8: Check The Refrigerant
Not cooling properly could be due to a low refrigerant level.
- Refrigerant is a vital component of any refrigerator, including mini-fridges. It's the compound that makes the fridge cool.
- This can only be fixed by a professional, as refrigerant handling requires special tools and knowledge. (Note: refrigerant is a dangerous chemical compound, so don't try to fix it yourself.)
- Contact a professional refrigeration technician to assess the problem. If the refrigerant is low, they can refill it if necessary.
Step 9: Call A Professional
If you have tried any of the above steps to troubleshoot and quickly fix your "un-cool" mini fridge without result, it’s time to call a professional repair technician. They will be able to diagnose the problem and repair your mini fridge.
We hope this guide has helped you to understand the steps you need to take when your mini fridge isn’t cooling. By following these steps, your fridge will soon be back in shape and maintain an optimal temperature for your food and drinks.
