Most common repairs needed to fix a LG refrigerator

Compressor Replacement

A locked refrigerator compressor can exhibit several symptoms indicative of a malfunction. The most noticeable sign is a lack of cooling in the refrigerator compartment, leading to elevated temperatures and the potential for food spoilage. The freezer may also fail to maintain the desired freezing temperatures, resulting in no ice production from the ice maker or dispenser. Additionally, you'll observe that the compressor is unusually silent or fails to produce its typical humming sound during operation. In some cases, the compressor may attempt to start but fail, resulting in repeated clicking noises. The inability of the compressor to circulate refrigerant properly can affect the defrosting process, leading to ice buildup in the freezer. Furthermore, a faulty compressor could send a sudden influx of melting frost to the drain line, causing it to back up, preventing adequate draining, and potentially causing water leaks.

Ice Maker Assembly Replacement

A faulty refrigerator ice maker can have diverse effects, impacting various aspects of the refrigerator's operation, including its ability to make ice. Increased noise during the ice-making process could indicate a problem in the ice maker's components. A malfunctioning ice maker may lead to water leaks around the ice maker assembly, potentially causing water puddles in and around the refrigerator. If the bail arm fails to shut off ice production, it could result in the ice maker drawer jamming due to an overproduction of ice, potentially leading to damage to the drawer or adjacent shelf. The failure of other components in a refrigerator that stops cooling will affect ice production, so a thorough inspection of the refrigerator by a Sears Home Services professional is recommended for an accurate diagnosis.

Electronic Control Board Replacement

A defective electronic control board can lead to various failures in a refrigerator, including a lack of power or cooling and water leaking. This is because the board serves as the brain of the refrigerator, controlling crucial operations such as regulating internal temperatures, running fans, managing defrost cycles, overseeing the ice maker, and controlling dispenser functions. If the electronic control board malfunctions, it can disrupt communication between many different components, including automatic doors if equipped. A failing board may cause a chattering or clicking noise from the refrigerator and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.

What to expect when you experience an LG refrigerator not working issue

How is the not working problem fixed?

Correcting most not working problems usually involves replacing the compressor, ice maker assembly or electronic control board. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a refrigerator that is not working

When the refrigerator is not working it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling LG refrigerator repair with a local Sears Home Services professional who can perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of refrigerator failures.

What to look out for with a refrigerator not working diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your refrigerator problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

LG Fridge Stopped Working: Expert Troubleshooting Tips

If your LG fridge stopped working altogether, follow these expert tips to troubleshoot the problem.

Check the house circuit breaker for the refrigerator and reset that circuit breaker if it’s tripped. That may restore electrical power to your LG fridge that stopped working.
If the house circuit breaker isn’t tripped check the refrigerator power cord. Plug the power cord back in if it is loose or unplugged.
Check the electrical outlet for power if you find no problems with the power cord being plugged in. Plug a small lamp or night light into the refrigerator electrical outlet to verify that it has power. If the electrical outlet is dead, have an electrician repair the outlet.

If the control has power but the compressor isn’t running, unplug the refrigerator and check the compressor start relay if you’re confident in your ability to safely access that part. It is the small box attached to the side of the compressor that helps start the motor. Remove the machine compartment cover on the back of the refrigerator cabinet and release the clip holding the start relay in place on the side of the compressor. Disconnect the wire from the start relay and pull it out. If you see burn marks or the compressor start relay rattles loudly when you shake it, it’s likely bad. Replacing that part may allow the compressor to start so your refrigerator begins working again.

If these tips don’t help when your LG fridge stopped working, schedule refrigerator repair service and we’ll send a Sears Home Services technician to your home to fix the problem.

Glossary Terms

What is Refrigerant?

Refrigerant is a chemical compound used in HVAC systems and refrigerators to absorb heat from the environment by cycling through states of evaporation and condensation, enabling the cooling process through its cycle of evaporation and condensation.

What is R-12 Refrigerant?

R-12 refrigerant, also known as Freon-12, is a chlorofluorocarbon (CFC) compound that was once widely used in air conditioning systems, refrigerators, and aerosol propellants before its phase-out due to environmental concerns.

What is CFC Certification?

CFC certification refers to the credentialing process that qualifies HVAC technicians to handle chlorofluorocarbons (CFCs) and other refrigerants in a manner that complies with environmental regulations. It is essential for professionals who install, maintain, or repair HVAC systems and refrigeration equipment.

What is a Refrigerator Thermostat?

A refrigerator thermostat is a device within a refrigerator that regulates its temperature by turning the cooling system on and off based on the interior temperature compared to the set desired temperature.
