LG Fridge Troubleshooting Guide

LG Fridge Troubleshooting Guide

LG refrigerators are innovative, modern appliances with advanced technology, but problems occur. If they’re too cold or hot, don’t defrost, are noisy, leak, or the icemaker or water dispenser doesn’t function properly, here are some troubleshooting solutions.

Common Issues with LG Refrigerators

Are you facing issues with your LG fridge freezer? Does it freeze your lettuce or cause your ice cream to melt? Are you determined to identify the problem and fix it yourself? If you’re experiencing temperature fluctuations, unusual noises, or troubles with the water or ice dispenser, let’s explore some standard refrigerator components that might be the culprit behind your LG refrigerator problem.


The temperature in the fridge and freezer needs to be just right, or food will spoil. The cooling problem could be due to the temperature settings needing adjustment, the temperature control thermostat, condenser coils, condenser or evaporator fan motor, start relay, start capacitor or thermistor, temperature control board or main control board, or the linear compressor.

LG Fridge Noise Problems

Does your fridge hum, bang, or rattle and keep you awake at night? Unusual or loud fridge noise can tell us of potential problems. Rattling, grinding, or squealing noises may be caused by the fan blades, evaporator or condenser fan motor, compressor, or water inlet valve. Bangs, thumps, or whistles often indicate a compressor problem.

Water dispenser

Is your water dispenser dribbling nonstop? Water trickles or doesn’t flow at all? The water dispenser may have a frozen or leaking water tube, faulty water inlet valve, dispenser control board, or low water pressure. Some issues may be linked to the ice maker or ice dispenser too.

LG Freezer Problems

The freezer is part of the refrigerator, so temperature and noise issues are linked. However, if the unit isn’t defrosting, it could be due to the defrost control board or thermostat, sensor or fuse, defrost timer or heater assembly, or the main control board.

A faulty ice maker could be due to the freezer temperature, water inlet valve, filter, water supply pressure, assembly, icemaker module, door or icemaker switches, ice level control board, etc., or icemaker mold thermostat.

Ice Dispenser

The ice dispenser is linked to the water dispenser and icemaker. So, if it has problems, they may be connected. It could be the dispenser control board or switch, auger motor, dispenser actuator, dispenser door motor or solenoid, ice bucket auger, or ice crusher blades.

LG Fridge Troubleshooting Suggestions

Once you’ve identified the problem, you need to try and isolate the cause to determine if you can fix it or need to hire a specialist who knows how to fix it. Fixing some issues may be simple, while others require special skills, training, tools, and parts. Always check the manual for part location and maintenance or repair suggestions too.


The most common LG refrigerator repairs are temperature issues. Check the settings and adjust if they are too low or high. Check the condenser coils for dust and debris and clean them with a vacuum.

Ensure the condenser and evaporator fans are free of obstructions and spin freely. The motor needs replacing if it doesn’t spin easily or is noisy. Check the continuity of each motor with a multimeter. If there is no continuity, replace the defective motor.

The start relay is another common problem. Check continuity between the start and run terminal sockets with a multimeter. Replace the start relay if there is no continuity or it has a burnt smell.

The temperature control thermostat controls the condenser and evaporator fan motors and compressor systems. Turn the thermostat from the highest to the lowest setting or vice versa. If it clicks, it’s fine. If there’s no click, check with a multimeter for continuity and replace if there is none.

Two other common LG refrigerator troubleshooting issues are the start capacitator which provides start-up power to the compressor, and the thermistor, which monitors temperatures in the fridge and freezer. If the capacitator or thermistor fails, the compressor often won’t start. Check both with a multimeter and replace them if defective.

The linear compressor is another common culprit that can be tested with a multimeter. However, if it is leaking or needs replacement, the repair must be carried out by a licensed technician.

The temperature control board is seldom the problem but check with a multimeter if other components test out. If it is defective, replace it. The same applies to the main control board.

LG Fridge Noise Problems

If the fridge is noisy, the most common cause is a fan blade. Check that the evaporator and condenser fans spin freely. Replace the affected motor if they don’t spin easily or squeak or squeal.

The evaporator fan motor is another common LG fridge repair. It should be replaced if it seems noisy and even louder when the fridge door opens. If the noise doesn’t increase when the door opens, check the condenser fan motor and replace it if necessary.

Banging, gurgling, thumping, or whistling noises commonly emanate from a failing compressor. The water inlet valve commonly makes a noise when filling the icemaker. It may be due to mineral deposits if it is louder than usual. It should be replaced, not cleaned.

Water Dispenser

If water doesn’t dispense, disconnect the tube at one end and try blowing through it. If no air goes through, it is plugged with ice. Ensure the freezer is between 0°F and 10°F.

The water inlet valve is another common problem. Test the continuity and replace it if defective. Also, the valve requires a flow 20psi to operate, so water pressure is essential.

A clogged water filter that can interfere with water flow should be replaced every six months.

The door switch prevents the flow of ice or water when the door is open. Check it for continuity and replace it if required.

Dispenser switches control different functions in the dispenser system. If one component doesn’t work, test with a multimeter, and replace it if there is no continuity. If all components fail, it is like a faulty dispenser control board.

Freezer Problems

Defrost and icemaker issues are freezer problems. If defrost isn’t functioning, test the defrost control board, heater, and thermostat using a multimeter. Another solution is to check the defrost sensor with a fuse and test for continuity.

The defrost thermostat is another issue. It monitors the evaporator coil temperatures and controls the defrost cycle. If everything tests out, check the main control board.

Ice Dispenser

Test each dispenser switch for continuity if the ice dispenser isn’t working. Inspect the dispenser actuator. If damaged, replace it. Ensure the auger motor spins and test with a multimeter. Also, test that the dispenser door motor is receiving power. If not, replace it.

The dispenser solenoid opens and closes the door flap. If it’s defective, replace it if everything checks out, and test and replace the dispenser control board.
