When your LG refrigerator stops cooling, there are a number of things that you can try to fix. These include resetting the compressor, repairing the fan motor, and resealing the doors. If these don’t work, you may want to consult a repair professional.
Noise problem
LG refrigerators are known to make noises, but you can usually resolve the problem without expensive in-home service calls. You can report your issue to LG Support or a trained technician.
Loud, whirring, or knocking sounds in your LG refrigerator is often an indication of a malfunctioning motor or fan. If the sound continues, you will need to replace the motor or fan.
The noise can also be caused by a faulty water inlet valve. The inlet valve is located on the bottom back of the refrigerator. You can check the valve by pressing the dispenser lever. If the valve is leaking, you will need to replace it.
If the noise continues, you may have a faulty evaporator fan motor. The blades of the fan will likely be obstructed, which will cause low airflow. If you don’t fix the problem, your LG refrigerator will not sustain proper temperatures.
Some other common causes for LG refrigerator noises are damaged evaporator and condenser fans. If you are not able to find the source of the noise, you can try turning the fan off and on.
Faulty seal system
LG refrigerators are known for their durability and reliability, but that doesn’t mean they’re without faults. There are a few common issues that can occur, including a faulty seal system, which can prevent the compressor from running.
Getting your refrigerator repaired is no easy feat. It can take weeks, or even months, to get it fixed. You’ll need to find a reliable and certified service provider.
Before committing to a repair, you might want to do some research online. This will give you a better idea of what the cost of repairing your appliance will be. You may also need to have an extended warranty to cover the repair.
It’s not uncommon for an LG refrigerator to fail two years after purchasing it. This usually happens with the linear technology compressor.
One of the best ways to identify a problem with your refrigerator is to do some troubleshooting. This includes checking the thermistor, which monitors the temperatures inside your fridge.
Faulty fan motor
If you’re not having any luck with your LG refrigerator, it may be due to a faulty fan motor. This component is essential to the fridge’s ability to stay cool. It draws air from the outside through the fan, passes it over the evaporator coils, and then back out through the bottom exhaust grill. If this is not working, you’ll need to have it checked out.
The condenser fan motor is usually found near the compressor in the lower rear of the fridge. To access the motor, you’ll need to open up the rear panel. To do this, you’ll need to unplug the refrigerator.
Before you plug it back in, you’ll want to perform a few tests. The first test is to check the voltage of the fan. To do this, you’ll need a digital multimeter. You should set it to measure AC voltage. If the readings are infinite, you know your motor is in trouble.
The second test is to check for continuity. You can do this by removing the control board from the fridge. If the wires are intact, you can simply take the control board to a repair center or parts store. If they’re not, you’ll need to replace the control board.
Resetting the compressor
When your LG refrigerator isn’t working properly, you might need to perform a refrigerator compressor reset. But before you do, you should first determine the cause of the problem. You can do this by performing an electrical or mechanical test.
First, you’ll need to shut down the main control panel on your LG fridge. This will reset the main control board or motherboard. It may take a couple of minutes to do so. Once you’ve finished, you can turn the unit back on.
Next, you’ll need to unplug the fridge from the wall. Typically, you’ll see the circuit breaker on the back of the refrigerator. It can be flipped to reset the power.
Once the unit is unplugged, you can use a digital multimeter to check for continuity between the start and run pins. If the meter reads “Continuity” or “Failure,” it’s possible that the capacitor or start relay has failed. You can then replace the part.
You may also have a problem with your ice maker. If it doesn’t dispense ice, it could be damaged. You should have it repaired by a technician. The problem may be caused by a faulty fan motor, the tank, or the defroster system.
