Refrigerator Repair: Tips to Fix a Cold but Not Frozen Fridge

When it comes to refrigerator repair, a common issue that many users face is a fridge that remains cold but does not freeze. This can be frustrating, as it prevents the appliance from functioning at its optimal level. Fortunately, there are several easy ways to resolve this problem. In this article, we will explore the different factors that can cause a fridge to stay cold but not freeze, and provide some tips to fix it.

Dirty Condenser Coil
The location of the condenser coil in a fridge can vary, with some being located below, behind, or on the walls of the appliance. The coil that is inside the fridge is typically better protected and therefore less likely to get dirty and require regular cleaning. However, for fridges where the coil is located on the back or bottom, it is important to clean it at least once every six months. This is because both sides are in an open area and easily accessible, making them more prone to accumulating dirt and debris.

Temperature Control Thermostat Not Working
The temperature control thermostat has a significant impact on the compressor, condenser fan, and evaporator fan motor. If the thermostat is not working properly, it can cause problems in the cooling system. To check if the thermostat is functioning normally, adjust it from a low setting to a high setting until you hear a "click" sound. If you don't hear a click, the thermostat is most likely damaged and needs to be replaced.

The Condenser Fan Not Working
The main function of the condenser fan is to draw air out of the condenser to cool the fridge. If the fan motor has a problem or is not working, air cannot be drawn into the condenser, making the fridge less cold or unable to freeze. Owners should check the fan motor bearings for wear and tear and replace them if necessary.

Closed Evaporator Coil
A closed evaporator coil is caused by a problem with the defrost system. The defrosting system turns on several times every day to melt ice that may have accumulated on the evaporator coil. If the defrost system is not working correctly, ice will form, and the fridge will be cold but not frozen. To test the continuity of the system, use a multimeter.

The Starter Relay Not Working
The starter relay supplies power to the compressor. If it doesn't work, the compressor will not work either, causing the fridge to lose performance. To check if the start relay is working, use a multimeter. If it smells burnt, it must be replaced immediately.

Defective Evaporator Fan Motor
The evaporator fan motor circulates air in the evaporator coil to all parts of the fridge. If this component stops working, the fridge cannot be used for freezing. To check the condition of the evaporator fan, open the freezer compartment door and activate the manual door switch. If the switch is in the ON or active position, but the evaporator fan motor still does not work, it needs to be replaced.

Compressor Not Working
The compressor compresses the refrigerant and circulates it through the condenser and evaporator. If the compressor is not working, it will be difficult for the fridge to cool down. A professional technician should be called in to fix the compressor.

Aside from these issues, owners should also keep the fridge away from heat-generating appliances such as ovens, stoves, and toasters. Additionally, unstable electrical voltage can cause malfunctions in electronic devices, including fridges. If the fridge is not cold, it is essential to check for any electrical power problems and contact an expert if necessary.

In conclusion, if your fridge is cold but not frozen, there are several potential causes that you can check for before calling in a professional technician. These include a dirty condenser coil, a faulty temperature control thermostat, a malfunctioning condenser fan, a closed evaporator coil, a defective starter relay, a faulty evaporator fan motor, and a non-working compressor. By identifying the root cause of the issue, you can take appropriate steps to fix it and ensure that your fridge is functioning properly. Remember to always exercise caution and safety when performing any repairs on your fridge, and don't hesitate to seek professional help if needed.
