LG Fridge Freezer Problems And Troubleshooting


LG fridge freezers have huge storage capacities holding up to 21 bags of food! With new bottom frost-free freezers meaning you’ll never have to defrost, and inverter linear compressors that are quieter and longer-lasting, these appliances are a kitchen must-have.

Occasionally things can go wrong and knowing where the issue is can stop your frustration and save you time – even if you can’t fix the glitch yourself. See some LG fridge freezer problems and troubleshooting here…

LG refrigerator not cooling

When the refrigerator cabinet feels warm there may be a problem with the optimal setting which may need to be lowered. Other aspects to consider are the cooling vents – these may be obstructed and will need to be cleared, as poor air circulation can stop the fridge from cooling properly.

The doors and drawers need to close and seal securely to prevent warm air from entering into the fridge. If door seals are damaged, they will need to be replaced. Another issue related to tight gasket seals is whether the appliance is sitting on a level floor. An unlevel platform can also affect the door alignments.

If the unit isn’t cooling at all this may be related to the control panel – the display mode may have to be disabled. All of these difficulties can quickly be diagnosed by an experienced appliance repair technician, and effectively put right.

LG refrigerator freezer not freezing

There are many factors that can cause the LG refrigerator freezer not cooling and these include dirty condenser coils which prevent the dissipation of heat – greatly reducing the cooling capacity of the freezer.

If the coils are frosted over this indicates a problem with the defrost system that turns the heater on throughout the day to melt away the accumulated frost. If the defrost heater is struggling to turn on it may need repairing or replacing.

The condenser fan motor draws air through the condenser and over the condenser coils – if the fan blades are obstructed this will prevent the freezer from cooling. Fan blade motor bearings also wear out over time resulting in the fan motor needing to be replaced.

LG bottom freezer refrigerator troubleshooting also takes into account other components such as the evaporator fan motor which draws air over the evaporator coils and circulates it throughout the freezer. If this is defective the freezer won’t cool, and the motor may need replacing.

If the start relay is faulty the compressor may run intermittently or not work at all. If this happens the freezer won’t cool – you may notice a burning smell around the start relay itself.

The compressor is a pump that condenses the refrigerant and circulates it through the evaporator and condenser coils. If this part isn’t working the freezer won’t cool – this needs to be assessed and tested with a multimeter.

The temperature control thermostat directs power to the compressor, evaporator fan motor, and the condenser fan motor. If this is defective the system won’t get any voltage and the freezer won’t cool. A replacement part can easily be fitted by an experienced appliance repair engineer.

Very occasionally your LG refrigerator may have faulty user control and display board, or a fault with the main control board. Your LG appliance technician will determine that all of the other components are working properly before replacing the control board itself.

If the freezer only freezes the top shelf there may be a sealed system leak in one of the shelves – and repairs can be very costly.
