Your LG freezer might not be sufficiently cold due to issues such as a defroster system problem or dirty condenser coils, fan failures or leaky door gaskets. While you might notice the cooling issue begin within the freezer, you’ll quickly find that the LG refrigerator and freezer not cool enough. To prevent food from spoiling it is essential to swiftly solve the issue.
How can you prevent air leaks from keeping your LG freezer too cold If your LG freezer isn’t warm enough to keep the frozen ice cream firm, or you notice lots of frost in the freezer the freezer, warm, humid air could be coming out of the refrigerator. Replace any damaged gaskets and inspect the door gaskets. If the gaskets are in good shape, but a door moves on its hinges, creating gaps between the gaskets and cabinet within door openings, adjust the hinges of your LG refrigerator so that gaskets can be sealed to the cabinet.
If the accumulation of frost is restricted to the freezer’s back wall, then the auto freeze system might be malfunctioning. When working properly, the defrost system melts frost off the evaporator coils every 8 hours or so to keep the air paths through the evaporator clear so the refrigerator and freezer compartments are properly cooled. If the defrost mechanism that is automatic breaks, frost builds up on the evaporator and the back wall of the freezer compartment. T
he frost buildup hinders cooling air flow through the evaporator, which means that the LG freezer isn’t able to cool properly. How to fix other problems that stop your freezer getting cold enough If the evaporator fan isn’t running, check the freezer compartment to see if it is cooling. If it’s not functioning you should replace the fan that is evaporating.
Dirty condenser coils can cause cooling problems in the freezer. It is recommended to disconnect your LG refrigerator to check for dust and dirt buildup. If your coils are filthy, clean them. Ensure that you clean the coils every when you perform routine LG refrigerator maintenance. If the freezer is not getting cold enough, check whether the condenser fan working. If the fan ceases to run and the condenser stops working, it will not cool refrigerant efficiently. If the condenser fan isn’t working, it must be replaced. These repairs may help solve the problems with your refrigerator.
Replace the LG refrigerator’s defrost sensors: The LG refrigerator’s defrost sensing device, also known as the bi-metal termination thermostat trips when the temperature of the refrigerator is at a certain level. The defrost sensor will trip when it senses that the temperature in the evaporator has been too high and shuts off the heating element.
The sensor for defrost could fail if it’s not functioning correctly. This can result in frost accumulation on the evaporator fins and eventually cause the refrigerator and freezer to not as cool. A volt/ohm tester can be used for checking the continuity of your defrost sensor. If it doesn’t show continuity at 0 degrees F then replace the defrost sensors. Clean the LG condenser tubes of the refrigerator. The dusty LG refrigerator coils could cause problems in the cooling system of your refrigerator as well as efficiency.
Cleaning condenser tubes must be done according to the directions in the owner’s manual. Unplug the LG refrigerator before accessing and cleaning the coils. The majority of LG refrigerators’ coils are located behind the bottom grill. By using a coil brush remove the condenser coils. Replace the LG condenser fan of the refrigerator The fan is situated inside the machine compartment of the LG fridge next to the compressor. It circulates air over the condenser coils to help chill the refrigerant that is hot that is coming from the compressor. The refrigerant is cooled prior to it is pumped through the expansion device to the evaporator. Replace any condenser fan that is defective.
Repair the LG refrigerator freezer defrost: In order to increase heat exchange in the LG refrigerator’s automatic defrost periodically melts frost from evaporator. The compressor will stop and the heating element for defrost turns on. If the compressor ceases to operate the frost melts off the evaporator’s fins. The condensate flows into the drip pan of an evaporator below the evaporator. It then flows through a drainage tube to the drain tray that is next to the compartment of the machine.
The condensate evaporates out of the drain pan prior to the next defrost cycled. If the defrost cycle fails, identify the problem and fix the issue. Replace the LG refrigerator fan The fan is installed on the top of the evaporator unit. It circulates air over the evaporator fins and through the cabinet to cool. Replace the fan if damaged. Repair the LG refrigerator thermostat control board. The temperature control board regulates the compressor and other components of the LG refrigerator. It is able to be tested by following the diagnostic testing procedures on the tech sheet of the refrigerator. If the temperature controller board doesn’t perform as it should or stops functioning, replace it.
Replace the LG refrigerator’s temperature control thermostat. The thermostat is equipped with an sensor tube that senses the temperature inside the LG refrigerator. The cabinet’s temperature is controlled by the thermostat, which is controlled by turning on and off the compressor according to the sensor tube that senses temperature. If it is unable to accurately measure temperature or is unable to turn off the compressor, the temperature control thermostat must be replaced. Replace the LG refrigerator thermistor. A faulty thermistor can send temperature information to the thermostat.
Replace the LG refrigerator’s defrost timingr. The defrost timingr electronic device that regulates the time between automatic defrost cycles. The motor in the defrost timer drives and controls the components. If the contact contacts for defrost move into the defrost cycles the compressor stops. The heater for defrost then turns on for a set period to melt off the frost of evaporator fins. This allows for a an efficient exchange of heat through the evaporator. After the time period for defrost ends the defrost timer’s contacts are reset to allow normal cooling operation within the LG refrigerator. It is necessary to replace the defrost timer in case it doesn’t advance when it is activated. Defective contacts on the timer could also cause the heater to not be able to energize or to continue to energize. In such cases, you should replace the timer.
The door to the freezer or the refrigerator door. Refrigerator and freezer doors are hinged and swing, which could be damaged or bent. The doors can begin to sag and allow warm moist to flow into the fridge. This creates excessive frost that could cause the drain tube or freezer to become frozen. Replacing or repairing the hinges of refrigerators requires you to adjust the hinges to make them function properly and ensure that they are aligned.
Replace the LG refrigerator door gasket: The door gasket attaches to the freezer or refrigerator door panel and prevents air from entering or escaping the cabinet when the door is shut. The gasket can be damaged and permit humid, warm air to enter the LG refrigerator door when it’s closed. This could cause frost damage as well as cooling issues. If your door seal is broken or damaged, you should replace it. Replace the LG refrigerator’s electrical control board. If it detects that the compressor needs to be running in order to cool the fridge, it sends voltage to the compressor and fans. The electronic control board receives signals from temperature sensors to monitor the temperatures inside the refrigerator and freezer. The electronic control boards controls the defrost cycles based on this information.
Electronic control boards are usually tested for faults to determine if they are functioning properly. There are a variety of tests can be performed however the most well-known is the Forced Defrost test. See the tech sheet for the instructions to run the diagnostic tests. If the electronic control board you have isn’t functioning correctly, you may need to replace it.
Routine LG refrigerator maintenance
Cleaning condenser tubes should be performed according to the instructions included in the owner’s manual. Prior to taking care of the coils, unplug the electrical outlet of your LG refrigerator. The coils are located behind the refrigerator’s front grills on the bottom. Clean the condenser coils using a coil brush. Other regular maintenance tasks include cleansing the water filter, changing the bottom front grille and adjustment of hinges in the event that doors aren’t sealed securely.
