  2. The primary purpose of having a refrigerator is to keep food and beverages cold. Cold temperatures help food stay fresh longer. The intention behind refrigeration is to gradually decrease the activity of bacteria (which all food carries) so that it takes longer for the bacteria to spoil the food. • Here are some of the causes which make your refrigerator not cooling properly. If your refrigerator is not cooling, here are the top six most probable causes

  3. Common Causes for Refrigerator is Not Cooling

  4. Dirty condenser coils • To cool the air inside the compartments refrigerators use a compressor to pump refrigerant through two different kinds of coils, the condenser coils usually located at the bottom of the appliance and the evaporator coils normally found behind the rear panel. • The refrigerant in gas form is first pumped into the condenser coils where the gas is condensed into a hot liquid the condenser coils dissipate the heat as liquid travels through them over time these coils will collect dust, dirt, and hair preventing the coils from properly dissipating the heat and reducing the refrigerator ability to cool. • You should use a condenser coil brush to clean off the coils periodically to ensure optimum refrigerator operation.

  5. Malfunctioning Condenser Fan Motor • A malfunctioning condenser fan motor could also prevent the refrigerator from cooling properly by failing to draw air past the condenser coils the component can fail mechanically or electrically. • A broken fan blade or a blade that does not turn freely could indicate a mechanical failure. • If the motor is receiving the power but doesn't run then the motor is probably failed electrically • Once the refrigerant has passed through the condenser coils and a capillary tube it travels to the evaporator coils where the liquid expands into a gas making the coils cold.

  6. Defective Evaporator Fan Motor • The evaporator fan motor draws air over the coils to cool it and circulates the air through the freezer and refrigerator compartments. • If the evaporator fan is defective the cold air will not be circulated into the refrigerator • If the motor is unusually noisy when the refrigerator is running or the fan blade does not run freely you should replace the motor with new one. You can also use multi meter to test the motor windings for continuity, if the motor tests negative for continuity then the component has failed electrically.

  7. Evaporator Frosted Over • The evaporator coils collect frost as the air passes over them since frost build-up can cause airflow problems the coils require periodic defrosting older models needed to be defrosted manually but most of today's models use an automatic defrost system consisting of • Defrost heater • Defrost thermostat and • Defrost control

  8. Depending on your model the control may be a defrost timer or defrost control board. • If the control thermostat or heater fails the evaporator coils will possible frost over causing poor cooling in the refrigerator. You can test both the heater and thermostat for continuity to determine if a continuous electrical path is present. • Be aware you'll need to test the thermostat at a temperature of 15 degrees Fahrenheit or lower for a proper reading if both thermostat and heater tests positive for continuity, it's likely that the control is defective and will need to be replaced

  9. Faulty Start Relay or Capacitor • The start relay or capacitor works in conjunction with the start winding to cycle the compressor on and off if the relay or capacitor is faulty the compressor may fail cycle properly or may not work at all.

  10. Malfunctioning Temperature Control Board • The temperature control board allows voltage to be sent to the compressor and the fan motors. • If the control board is malfunctioning the cooling system won't cycle on. Since this is not a common problem you should verify that other components are working properly before replacing the board
