My Fridge Is Not Cooling or Freezer Not Working

Troubleshooting fridge not cooling and freezer not working. 5 Common causes

A fridge is a vital appliance in any home or business premises, as it keeps, stores and maintains freshness of the food that we eat daily. Having a fridge not working or freezer full of stored meat, vegetables and any other food, not working is a nightmaire. In fact it is one of the common household or business emergencies that does not require the police or ambulance, but an Appliance Technician. 

There are several causes for your fridge not cooling or freezer not freezing enough to preserve your food. Here we look at the five common causes that you may want to consider in diagnosing the fault, whether you are a DIY person.

1. Dirty or Clogged Condenser Coils

The condenser is the part of a refrigeration system that removes heat from the refrigerant. Over time, the condenser coils at the back or bottom of your fridge can accumulate dust, dirt, and debris, hindering their ability to release heat effectively. This buildup forces the compressor to work harder, leading to inadequate cooling. To remedy this, unplug your fridge and use a vacuum cleaner with a brush attachment to gently remove the buildup from the coils. Repeat this process every six months to keep your coils clean and your fridge running efficiently.

2. Faulty Evaporator Fan

The evaporator fan is responsible for circulating cold air from the evaporator coils throughout the fridge and freezer compartments. If this fan malfunctions, it disrupts the airflow, causing inconsistent cooling or no cooling at all. To diagnose this issue, listen for any unusual noises coming from the fridge. If you don’t hear the fan running, it may need to be replaced. Remove any obstacles that may be blocking the fan blades, and if the problem persists, consult a professional technician to replace the fan motor.

3. Low Refrigerant Levels

Refrigerant is a cooling agent that absorbs heat and leaves cool air behind when passed through a compressor and evaporator. It changes from a liquid to vapor or gas state as it goes through the refrigeration process. It is responsible for absorbing heat from inside the fridge and transferring it outside. If there’s a leak in the refrigerant system or if the levels are insufficient, your fridge won’t be able to cool properly. Signs of low refrigerant levels include reduced cooling capacity and ice buildup on the evaporator coils. A qualified technician can locate and repair any leaks in the system, recharge the refrigerant, and ensure proper pressure levels to restore your fridge’s cooling performance.

4. Defective Defrost Timer or Thermostat

The defrost timer and thermostat work together to regulate the defrost cycle in your fridge. If either of these components malfunctions, it can lead to excessive ice buildup on the evaporator coils, obstructing airflow and preventing proper cooling. Test the defrost timer by manually advancing it until the compressor turns off. If the defrost heater activates, the timer is likely working correctly. Similarly, test the thermostat for continuity using a multimeter. Replace any defective components to restore proper defrosting and cooling operation

5. Damaged or Worn Door Seals

The door seals, also known as gaskets, create an airtight seal when the fridge doors are closed, preventing warm air from entering and cold air from escaping. However, over time, the seals can become worn, torn, or misaligned, compromising their effectiveness. Inspect the seals for any signs of damage, such as cracks, tears, or gaps. If you notice any issues, replace the seals to ensure a tight seal and optimal cooling performance.
