LG Freezer Isn’t Freezing? Immediate Steps to Take

Key Points

  • The most common reason your LG freezer isn’t freezing is a lack of power.
  • If power isn’t the cause, you could have set the freezer temperature too high.
  • Another common reason is an improperly closed door.
  • A blocked air vent can also cause the freezer not to freeze properly.
  • Cleaning the mechanical compartment where the condenser coils are located could improve your LG freezer’s performance.

There is hardly something more disheartening than opening your freezer’s door, ready to whip up a quick meal, just to find that the freezer didn’t freeze and all your food has gone bad. Some of the most common issues include improper use, such as turning off the refrigerator accidentally, setting the freezer temperature incorrectly, or forgetting the door open. Other issues could be more serious, but you can still take steps to solve them. Let’s see what to do if your LG freezer isn’t freezing and you’re sure you’re using the appliance correctly.

Step 1: Reset the Power and Control Board

Resetting the power and control board could restore the freezer’s performance.

Most LG refrigerators have a safe mode that is activated when the appliance experiences power outages. This mode protects the fridge’s components from electrical overloading, and it should return to normal mode automatically when power returns. However, the appliance could sometimes remain stuck in safe mode.

If your home was recently affected by blackouts, you can reset your LG refrigerator’s power to turn off the safe mode. Simply unplug the appliance (or switch off the circuit breaker) and wait for five minutes. Return power to the fridge, then open the freezer door and push the light switch three times. This will initiate the cooling cycle. Monitor the temperature for at least 24 hours to see if it works.

If the freezer still doesn’t freeze, you can also reset the control board. You can do this at any moment while the refrigerator is running. Open the fridge compartment door and locate the refrigerator and ice plus buttons. Press and hold for around five seconds until the panel chimes. The temperature settings will now be reset so you can set the temperature again for both the fridge and the freezer compartment. Monitor for 24 hours to see if it worked.

Step 2: Defrost the Freezer

An accumulation of ice could prevent your LG freezer from freezing.

Almost all LG refrigerators have an automatic defrost function that prevents the accumulation of ice in the freezer compartment. However, if the temperature is set too low or you leave the freezer door open for too long, ice could build up.

Excess ice could block the vents between the freezer and fridge compartments, compromising the freezing function. So, if the freezer is filled with ice, but you notice the food isn’t frozen properly, you can defrost the freezer manually.

Remove all the food from your fridge and freezer, and unplug the appliance. Wait until all the ice thaws, then remove excess water and clean the refrigerator. Dry it thoroughly, plug it back in, and wait for 24 hours to monitor the freezing performance.

Step 3: Check the Door Seals

Another common issue why the LG freezer isn’t freezing is a broken door seal. In this instance, your refrigerator would appear to work normally. However, the broken seal would allow warm air from the kitchen to seep into the freezer, compromising normal operation.

Open the freezer door and inspect the rubber gasket around the edges. Check for damages or obstructions that could prevent it from sealing the freezer compartment when the door is closed, such as grime or food residues. Clean the door seal if necessary or call a technician to replace it if it is damaged.

Step 4: Check the Thermostat

A faulty thermostat could compromise freezing.

If everything seems right, but the freezer doesn’t freeze, the reason could be a faulty thermostat. This sensor is responsible for registering the temperature inside the refrigerator and switching on cooling when it rises above a certain threshold. A broken thermostat may not register the temperature correctly, or it may not be able to switch on the cooling process.

A simple way to test the thermostat is by turning it from the lowest to the highest setting. A click sound indicates the thermostat is working properly. So, if you don’t hear this sound, the component might need replacement.

If you’re skilled enough, you can also test the thermostat for continuity with a multimeter, looking for a resistance value between zero and one ohm. Unfortunately, there is little you can do if the thermostat is broken other than calling in a technician.

Step 5: Clean the Mechanical Compartment

Keep the mechanical compartment clean to prevent poor freezing performance.

LG refrigerators use condenser coils to dissipate warm air from the unit and keep the interior at the set temperature. These condenser coils could become too dirty to work properly, especially if your environment is excessively dusty or there is significant pet traffic. Cleaning the mechanical compartment, where the condenser coils are located, could improve your freezer’s performance.

Unplug the appliance and pull it away from the wall. Locate the mechanical compartment at the bottom of the unit and remove the panel in front of it. Use a vacuum cleaner to remove all dust and grime from the condenser coils.

Step 6: Check for Other Technical Issues

Other components, such as the compressor, capacitor, or relay, could also compromise the freezing function.

Beyond the issues above, there are other technical components that could impact the freezer’s performance. For instance, a faulty compressor, capacitor, or relay can prevent the cooling function. Coolant leakage is another possible problem, or the control board could be faulty.

All these problems require professional assistance. So, if you’re sure you’re using the appliance correctly and the steps above didn’t solve the issue, you should call in a technician.
