LG is known for the high-end household appliances and they even have other electronics. However, their fridges tend to break down even if you choose the best one in the market. To be honest, the issues like LG fridge not cooling are common and are easy to fix. So, if you are annoyed that your fridge won’t cool and the food will get worse, we are sharing the potential reasons and solutions.
LG Fridge Not Cooling
1) Coils
The issue can occur when the coils (we are talking about the condenser ones) are too dirty. If you don’t know, the condenser coils are responsible for keeping the LG fridge cool as it chills up the hot air that comes from under the fridge. So, when these coils get dirty, there will be cooling issues. To inspect these coils, you need to unplug it and look for the coils (you might have to lay it down because these cools are placed underneath). When you find the coil, see if they are dirty.
In case the coils are actually dirty, clean them up with damp cloth and soap solutions. However, make sure that you clean everything dry before you switch on the fridge. When the coils are cleaned and the fridge is switched on, wait for at least six hours to let the fridge start cooling. However, if there is no cooling up even after six hours, you can check the next solution.
2) Condenser Motor
If the coils aren’t solving your problem, the next step should be checking the condenser motor. This part is responsible for drawing air all around the coils as well as the compressor. So, when the fan motor doesn’t work, the fridge will not cool up. That being said, you can consult the following instructions for checking the motor, such as;
- You need to switch off the LG fridge and always take out the plug
- Look for the condenser fan motor and make sure that the fridge’s fan blade doesn’t have any obstruction around (there shouldn’t be any visible object around it)
- Now, try to rotate the fan blade manually. In case you have to apply too much pressure to move it, it has gone bad and the entire fan motor has to be replaced
- On the other hand, if the fridge’s fan blade is moving freely, use a multimeter the inspect the continuity. If there is continuity, the motor is working optimally and you must check out the next solution to fix the cooling
3) Evaporator Motor
The evaporator motor is responsible for circulating air all across the evaporator coils as well as into the fridge. In addition, it circulates air over the freezer areas. So, when the evaporator fan motor stops working, it won’t be able to create a cooling and you should follow the steps mentioned below the inspect the evaporator fan motor;
- Switch off the fridge and leave the plug out
- Consult your manual to trace the evaporator motor (it will be around the freezer area if you don’t have a manual)
- Now, check the fan; if there is too much noise when it operates. If the sounds are noisy, it needs to be replaced immediately to resume cooling
- On the contrary, if noisiness is not there, you should turn it around manually (in instance that the required movement is requiring too much pressure, you have to replace it
Still, if the blade is turning around fine, use a multimeter the inspect the continuity of the motor. If there is enough continuity, the evaporator fan motor is operating normally and isn’t the reason behind cooling. Also, if there isn’t any continuity, it’s obvious that you have should replace the entire assembly.
4) The Start Relay
Another reason behind the cooling issue could be a damaged start relay. This specific part of the fridge is responsible for initiating winding and it will start up the compressor. On the other hand, when the start relay is defective, it will have a hard time starting the compressor. Now, to check or inspect the relay, we have added the instructions that will help;
- Switch off the LG fridge and take out the switch
- Now, look for the start relay & test the continuity through a multimeter. You must check the continuity between the start and run sockets (the terminal ones)
- If there is no continuity, the start relay needs a replacement, otherwise, you must move to the next part
5) Temperature Thermostat
The temperature thermostat is responsible for sending voltages to the compressor of a fridge, condenser motor and evaporator motor. When the temperature thermostat stops working, the cooling will be impacted. You can check this component by setting it to the lowest as well as the highest settings. While you are turning around the temperature thermostat, do look for the clicking sound.
The clicking sound will ensure that the thermostat is working normally, and when it doesn’t, check the continuity through a multimeter). If the continuity is there, the thermostat is fine and you don’t need to get it replaced. However, you can check the next step for fixing the cooling problem.
6) Start Capacitor
Start capacitor is responsible for starting up the compressor because it sends the power boost to it. When the fridge stops cooling, there are high chances that your fridge’s start capacitor isn’t working. The functionality can be checked by the multimeter (availability of the continuity promises stable functionality). However, if the multimeter doesn’t show continuity, get it replaced and cooling will start in no time.
7) Thermistor
This component is responsible for monitoring the fridge’s temperature and also sends these readings to the primary control board. Also, when the thermistor stops working, it will adversely impact the cooling because it will keep sending incorrect temperature readings. So, just use the multimeter because there will be continuity if the thermistor is working reliably. On the contrary, if there is no contrary, get the thermistor replaced.
With this article, we outlined various components that might be the reason why your fridge isn’t cooling. However, we do suggest that you ask for LG technical support if the fridge is in warranty because you might score free repair and part repair.
