Cleanse evaporator coils
The next step is moving onto the Evaporator coils. The coils will regulate the airflow entering the refrigerator and ensure that the temperature is at the ideal level. In the absence of this, the principal problem that pops up is the appearance of frost. If there’s a lot of ice on the coils, it may cause a blockage against the airflow. It’s why it’s crucial to keep your coils as tidy as possible. To accomplish this, you’re likely to need to clean the frost off and examine the refrigerator’s temperature settings. This is an excellent remedy if you suspect that the airflow affect and there’s no other issue in the temperature.
Make sure the motor’s fan is working good
After you’ve cleaned the coils that evaporate, it’s time to turn your attention toward the motor. The motor is responsible for driving the fan blades and allowing air to flow through the LG fridge. This is the reason why you need to be aware of the blades. If there’s debris in them, the fan blades don’t rotate as they suppose to. This is because the airflow slows down, and the component gets hotter. Your aim is to ensure that the debris takes and is out of the way to allow the motor’s blades to work.

Reset your fridge by unplugging it
The final alternative is to reset the refrigerator. You’ll have to start by unplugging your LG refrigerator and letting it sit for about 15 minutes. The goal is to make sure that the fridge isn’t running electricity through it when you’re setting it. It’s as simple as waiting 15 minutes before plugging it back into. The next step is to check the thermostat to determine whether there are any temperature issues. If everything is normal, you’ll observe the temperature fluctuation after a short time.
Factors that LG refrigerators aren’t cooling
Condenser fan that is not working properly
LG is a well-known maker of household appliances and comes with a cooling system built on the continuous circulation of cool air. One of the most critical components of this system is the condenser fans – it is a device that moves air over coils that cool the air. If the airflow block or not present, the issue is in the dirty condenser’s fan blades or the motor is damaged.
Check to make sure you have turned off the power before you start working on anything that requires electricity. The first step to check is to search for particles on the motor or in its vicinity. Then ensure that it is spinning freely. After that, you should test the motor’s continuity by using a multimeter. This will find out if the issue is in the motor’s winding. If you suspect the problem is with the engine, you’ll require to contact LG to request a replacement.
The evaporator motor is not working
In the case of refrigerators, many of them are equipped with one fan for evaporation, which is located at the rear part of the freezer. The fan cools the refrigerator and freezer sections by moving air over the cooling coils and then into the areas. If it’s not producing sufficient cool air, the refrigerator won’t keep the refrigerator or freezer sections cool.
Switch off the appliance, and then locate the motor of the evaporator fan within the freezer compartment. If you notice that the engine is thunderous, it is an indication that it needs to be replaced. Then turn the fan blade manually. If it is stuck, take it off and replace the evaporator motor. Check the engine of the fan for continuity. If it fails, then we need to replace the motor.
Failed linear compressor inverter
LG refrigerators are made to remain calm, regardless of the compartments. However, if your refrigerator isn’t cooling correctly, you could have a few issues. If your refrigerator is hot and the freezer remains cold, airflow is restricted. It could be from a burned defrost thermal fuse or the evaporator fan failing. If your fridge is hot while the freezer remains cold, it could result from a malfunctioning linear compressor for the inverter or the start relay.
LG refrigerators decided to update their compressors and then test them extensively to ensure their reliability. The new generation of LG refrigerators is designed to resolve the most common issues like cooling issues and frequently breaking. Pay attention. If your fridge isn’t cooling properly and you’re not sure why to remove it from its place, take off the panel on the back, and check whether the compressor is operating.
Faulty start relay for compressor
LG refrigerators are equipped with two essential components of the cooling process: the compressor and the starter relay. If the start relay isn’t functioning correctly, it could also stop the compressor from working correctly. To fix the issue, you’ll need to lift the panels on the back of your LG refrigerator to reach the inside of it. The first thing to do is disconnect the outlet from the refrigerator. If your refrigerator is connected to a water line, you must disconnect it. Then, move the fridge to access its back.
The relay for starting is situated close to the compressor. We’ll use a multimeter to check if there’s any connection between the run and start terminals. If that is not the case, we’ll have to change the relay. It’s time to reach out to LG to learn how to replace the start relay in your refrigerator. After replacing the component, make sure you turn it back up and connect the waterline if it disconnects. After completing all of that, plug it into the outlet and switch it on.
Dirty condensing coils
Condenser coils are among the most vital component that any refrigeration system has. They hold the coolant and move it around these coils. The coolant squelches the heat from the air inside the refrigerator, and the waves draw heat from the fridge. Condenser units are essential for keeping the refrigerator at the correct temperature. When you feel the fridge is hot, it may be a problem within the condenser unit. Or, the coils might require cleaning. To access the condenser, you’ll need to reach the refrigerator’s back by removing the bottom.
If you require to move the appliance, disconnect the unit and disconnect the waterline. Before inspecting it, make sure that the team is disengaged and disconnected. If your coils are dirty, it is recommended that you take out any particles with a stiff brush or an air hose. Employ a toothbrush with soapy water or a scrubbing pad to get rid of hardened dirt.
Incorrect temperature control thermostat
The thermostat is among the electrical elements of the LG refrigerator. It controls how three cooling components (Evaporator fan condenser, condenser, and compressor) will work. If it’s not functioning correctly, one or more of these components won’t function correctly. If you suspect that the issue is with the thermostat for temperature control, you’ll have to look at the inside of the device. The thermostat is easy to find and is located at the lower part of the appliance. To verify if it’s functioning, turn the knob and see whether the knob clicks.
When you change your thermostat, it is essential to ensure that it’s working correctly. This is a step to ensure there’s no issue with the thermostat while you adjust it. If you find that the thermostat is not working correctly, it recommends that you call LG and request a replacement for your refrigerator.
These are the steps to take if you are dealing with the LG refrigerator temperature control issue you are dealing with. When you experience LG refrigerators that have problems controlling temperature, many reasons to blame. Some include an unresponsive thermostat, blocked fan blades or frost on the coils that evaporate. To fix LG refrigerator temperature control problem, switch your thermostat down to its lowest level and then to the highest setting, waiting for a “click” sound. If the sound doesn’t occur, the thermostat needs to be replaced. This is why you need to be meticulous and follow the steps outlined in this article. LG refrigerator temperature issues will vary, and you’ll need to go through the steps step by step. For some, it’s the thermostat, while others will be dealing with a damaged motor to take care of.
