Why Your Mini Fridge Is Not Cold

mini fridge is not cold

If your mini fridge is not cold, it may be because the cooling system is not functioning properly. Some common problems are related to the thermostat, condenser fan motor, and condenser coils. Other problems are related to the control board. If you have tried all the above mentioned methods and the problem still persists, you need to replace the evaporator fan unit.

Problems with condenser fan motor

If your mini fridge is not cooling as well as it should, the problem could be the condenser fan motor. Without it, the fridge will struggle to exchange heat and keep the temperature within the proper range. You can easily replace the motor by unscrewing the cover. To make sure that the fan is rotating properly, make sure that it is free of any obstructions. After this, you can test the mini fridge to see whether it has been affected by a faulty condenser fan motor.

If the fan blades don’t spin freely, check for mechanical obstructions or a loose bearing. If the fan blades are twisted, they could indicate a damaged motor shaft. Alternatively, they could also be jammed by a faulty capacitor. If the capacitor has failed, you can try manually spinning the fan to get it going again.

The most straightforward way to diagnose this problem is to check the wiring. If you have a multimeter, set it to Ohms and test the continuity of each wire. If it still fails to spin, check whether the motor is connected to any other components.

Problems with thermostat

If your mini fridge is not cooling, you should investigate its thermostat. The thermostat controls the temperature of the mini fridge, and if it stops working, the fridge will not be able to cool the contents. Check the thermostat for signs of damage or malfunction and replace it if needed. If the thermostat is in working order, the refrigerator will be able to keep the contents cool, and will not overheat.

You can determine if the thermostat is the culprit if the fridge freezes the contents. In this case, you can use an appliance thermometer to check the temperature and unfreeze the frozen foods. If the thermostat is not working correctly, you’ll likely need to replace the mini fridge thermostat. Depending on the problem, this repair may cost a few dollars. However, the cost of replacing a thermostat is usually not worth the hassle.

If your mini fridge is making a clicking sound or humming sound when you turn it on, it’s most likely the thermostat. Check whether the wires are intact. If so, you should replace the wires. If this doesn’t solve the problem, you can call for professional service.

Problems with condenser coils

If your mini fridge isn’t cooling properly, you may be experiencing problems with the condenser coils. The coils are located in the back of your refrigerator and tend to get dirty over time. You can clean them by using an electronic duster or a manual brush. Dirty coils can lead to a faulty compressor, which can cost as much as $300. To avoid these costs, it is usually cheaper to replace the mini fridge.

The problem may be caused by several factors. First, the water filter head or the housing may be cracked, resulting in leaks. Another possible cause is a faulty defrost heater assembly. This will cause the evaporator coils to become frosted, causing a lack of cooling. A malfunctioning thermostat is also another cause. If it is not working properly, the thermostat will send an incorrect signal to the compressor, which will cause the fridge to overcool and not cool properly.

Another common problem is that the compressor in your mini fridge is not working efficiently. This can cause your refrigerator to malfunction. This can lead to a blowout or overheating. Make sure that you unplug the refrigerator before you work on it.

Problems with control board

If your mini fridge is having problems cooling, the problem might be with the control board. The control board is like the brain of your mini fridge. If it is not working properly, you should replace it. Replacing the control board is not a cheap and time-consuming job, and it is only possible if you have a new mini fridge.

The control board is attached to the control box, which is attached to the top or side of the mini fridge. Check the board for burnt connections or damaged foil, or arcing. If these components aren’t the issue, you might need to replace the control board. If the problem persists, contact a repair service professional for further diagnosis.

The control board is a critical component of a mini fridge, and it needs to be carefully inspected to find the exact problem. If you don’t have an access to the control board, you can check the other components of the unit, such as the thermostat and the evaporator coils. Ensure that the thermostat is working properly to prevent a dangerous overheating situation.
