LG Refrigerator Not Cooling – Why Its Happening? [Explained With Details]

Refrigerator is one of the most important kitchen appliances in our daily life. For keeping food fresh for a long time, we use Refrigerator. Almost all the family have a refrigerator.

There is an claim about the LG refrigerator not cooling properly. Unfortunately, many LG Refrigerator users noticed that their food does not stay cool. Because the temperature is not cold as it has to be.

Some experts said that this problem 90% related to the failure of linear compressor and 10% for start relay if Lg refrigerator doesn’t cool in both sections. But if the freezer is cold on the other hand fridge compartment is warm then an 80% problem is happened for airflow, burnt to deforest thermal fuse or failure of the evaporator fan. In this case, there are some specific reasons for not cooling are discussed below

LG Refrigerator Not Cooling

Dirty Condenser Coils

Condenser coils are the main cooling part of a Refrigerator.  If it becomes dirty then your LG Refrigerator will not cool properly. Most of the situations of cooling problem, Technicians finds condense coil dirty. The condenser coil works for dissipating the heat from Refrigerator so that freeze can maintain the cooling temperature.

If the condenser coil becomes dirty, it becomes unable to maintain the cooling temperature of the machine. Because then it is not able to throw out the heated air from the refrigerator. So there are some solutions for cleaning dirty condenser coils At first, you just open the back unit at the bottom of the machine. If you see any dirty element on the condenser coil then remove it with a stiff brush or compressed air. Before doing it you must unplug the unit from electricity.

Failure Condenser Fan Motor

Condenser fan motor failure is another important factor for not cooling the refrigerator. Because this fan brings air over the condenser coil to cool it properly. To check the fan, go to the bottom part of the refrigerator’s back side, and open the cover .then check if the condenser fan does not run properly then remove it and replace it with a new one. But remember before changing it disconnect the electricity and water supply in the refrigerator. Better you can hire a technician to change the Condenser fan motor.

How Can You Tell If Your LG Fridge Compressor Is Defective?

The simplest method to discover whether the compressor has failed is to lift the fridge slightly away from the wall and listen carefully. If the motor is making a tiny humming sound yet the temperature is above what it should be, there is a chance that the compressor is malfunctioning.

Evaporator Fan Motor Failure

Evaporator Fan Motor Failure

Another important factor that is responsible for not cooling the refrigerator properly and is evaporator fan motor failure.

  • The evaporator fan motor is the supplier of air to both compartments of the refrigerator across the cooling coil.
  • If it doesn’t work properly or discontinue then both sections will not be cool properly or not cool either.
  • To check the fun you must locate the position of it. Normally it locates behind the freezer side.
  • Check, if the Evaporator Fan Motor is running with loud sound then it should be replaced.
  • Or if the fun does not sound when it starts and you are not able to replace it.
  • Call a technician to replace it.

Start Relay Problem

Start relay is a crucial issue for not cooling the refrigerator. If the start relay is faulty then the compressor will not work properly or it will not run either. When the compressor will not run then it is obvious the refrigerator will not cool naturally.

TO check the start relay you will go to the bottom part of the body and access the panel where the device is located adjacent to the compressor. You have to check it with multi checker if it ok then the problem with another thing. Or if you found the problem with the start relay then replace it with the new one. You should call an expert technician to replace it if you are not willing to do it.

Failure of Temperature Control Thermostat

The thermostat is another crucial part of the LG refrigerator. The thermostat monitors the temperature of the fridge after that it will send the temperature report to the main control board. And then the main control board manages it according to reading temperature. When it won’t read temperature properly then it sends an incorrect report to the mainboard.

After that, the fridge will not cool down at the perfect temperature. To check it, At first, unplug the fridge, Check the thermostat to locate at the bottom of the fridge. Check it with a multi-checker if it works ok then. The problem is not in the thermostat check another component of the fridge. Or if you find a problem then replaces it with the help of an expert technician.

Failure Start Capacitor

Failure of the capacitor may be another reason for not cooling the Lg fridge. Start capacitor helps the compressor to start up properly. When you start the fridge the device helps as a charged battery and boosts the compressor to start. If the capacitor becomes damaged then the compressor will not start at all. Check it with a capacitor meter to know its working ability. It is dead, then replace it with the help of an expert.

Compressor Problem

Compressor problem

Compressor plays an important role to refrigerant and circulates the evaporator and condenser coils. After all checking of your Lg fridge, still you notice that your refrigerator does not cool enough. Then you should try to check the Compressor. It might be defective. Check the compressor with multi-meter if find any issue then call expert technician to replace it or repair it.

Temperature Control Board Failure

  • The temperature control board supplies electricity to the fan motor and compressor
  • If your Lg Fridge does not cool properly then check the temperature control board.
  • It might be misdiagnosed often. Because it can obviously happen. So check all the parts correctly and fix them.


I hope now you know why the LG refrigerator not cooling properly.

Frequently Asked Questions:

1.How Can I Repair My LG Refrigerator That Isn’t Cooling?

Ans: To RESET THE REFRIGERATOR, disconnect the appliance or trip the circuit breaker for 30 seconds. Within 24 hours, you should hear the compressor restart, and the device should settle and begin cooling. If not, there is a power supply issue and the machine will need to be repaired.

2.What’s The Deal With My Refrigerator Running But Not Cooling?

Ans: Poor cooling can be caused by clogged coils. Check that nothing is trapped in the condenser fan and that it spins freely (models with rear coils will not have a fan). Clean the fan blades and manually spin the fan to determine if it’s stuck. Connect the refrigerator and ensure that the fan runs when the compressor is turned on.

3.Is The LG Refrigerator Equipped With A Reset Button?

Ans: How Do You Reset the Control Panel on Your LG Refrigerator? Hold down the REFRIGERATOR and ICE PLUS buttons for five seconds with both fridge doors open media. The control panel will sound and the heat settings will appear after 5 seconds of holding the buttons to indicate that DEMO MODE has been disabled.

4.Why Is My Fridge Becoming Warm?

Ans: The refrigerator is overflowing. The cold air that is constantly pumped through the appliance keeps your refrigerator at the right temperature. If your fresh food compartment is overcrowded, the cold air may not flow effectively, resulting in a warm refrigerator.

5.How Can I Tell If My LG Refrigerator Compressor Is Faulty?

Ans: The simplest method to discover whether the compressor has failed is to lift the fridge slightly away from the wall and listen carefully. If the motor is making a tiny humming sound yet the temperature is above what it should be, there is a chance that the compressor is malfunctioning.
