Introduction to LG Refrigerator Compressor Not Running
Your LG refrigerator is more than just a pretty face in your kitchen. It’s a complex system and its heartbeat? That’s the compressor. But what happens when this crucial part stops running? Chaos, friends, chaos. You might be looking at an LG fridge full of lukewarm drinks and spoiling food. So, let’s get a handle on this situation pronto!
Brief Overview of LG Refrigerator Compressor Issues
Imagine you’ve just returned from grocery shopping. You load up your fridge, close the door, and then… silence. Instead of the usual hum of your LG refrigerator, you’re met with a concerning quiet. It could be your compressor, a critical component in cooling, is having a moment.
The compressor’s job is a bit like a marathon runner – it’s designed to keep going, against all odds. When it doesn’t, there’s usually a reason. Maybe it’s a faulty thermostat or a wonky start relay, or perhaps the compressor motor itself has decided to retire early. The tricky part? Identifying which piece of the puzzle is causing your LG refrigerator compressor not to run.
Understanding the Role of the Compressor in Your LG Refrigerator
Do you know what the heart does in your body? Well, in the body of your refrigerator, the compressor does a similar job. It circulates the refrigerant, which absorbs heat from the inside of the fridge and releases it outside, keeping your groceries nicely chilled.
Basic Function of a Refrigerator Compressor
The refrigerator compressor, in its simplest terms, is the heart of your fridge’s cooling system. It circulates the refrigerant, absorbs heat, and expels it outside. It’s sort of like a merry-go-round: the compressor moves the refrigerant around in a cycle, pulling in warm refrigerant gas, pressurizing it, and sending it out as a cooler liquid.
How a Failing Compressor Affects Refrigerator Performance
So, we’ve established that a compressor is like the beating heart of your LG refrigerator. But what happens when this heart starts to falter? Well, much like in the human body, it’s not good news. A failing compressor can drastically impact the performance of your refrigerator, leading to a range of issues.
First and foremost, a malfunctioning compressor can result in insufficient cooling. If the compressor isn’t running, it can’t push the refrigerant through the system to remove heat. This means the interior temperature of your refrigerator may rise, potentially spoiling your food. This can be more than just an inconvenience. It can also be a waste of money and resources. After all, nobody wants to throw away a week’s worth of groceries because their refrigerator stopped doing its job.
Another consequence of a failing compressor is excessive noise. While your refrigerator normally operates quietly, a faulty compressor may cause it to generate strange noises like humming, buzzing, or rattling. These sounds are a clear sign that something is wrong. Remember, your refrigerator shouldn’t sound like a construction site.
In some cases, a failing compressor might also cause your refrigerator to overheat. This can happen if the compressor is working too hard or if it’s not properly cooling down after running. Overheating not only impacts your refrigerator’s performance but can also be a potential safety risk. If the outer surface of your refrigerator feels hotter than normal to the touch, it’s time to investigate.
Ultimately, a failing compressor can cause your LG refrigerator to lose its cool (literally), making it less efficient and potentially unsafe. Recognizing these signs and understanding how a faulty compressor affects your refrigerator’s performance is the first step in resolving the issue and restoring your fridge to its former glory.
Common Signs Your LG Fridge Compressor Is Not Working
Let’s face it, we often take our refrigerators for granted. They’re like that silent friend who’s always there for us. But when things go south, it’s hard to ignore. Here are some tell-tale signs your LG fridge compressor might be on strike.
No Cooling
Are your favorite drinks losing their chill? Is the butter softer than usual? These could be signs of your compressor not doing its job. Without the compressor’s continual cycle, the refrigerant can’t do its heat-shifting magic, and your fridge’s inside starts warming up. Not quite the tropical vacation you were dreaming about, huh?
Strange Noises
When your fridge starts making noises that would rival a horror movie soundtrack, it’s definitely not a good sign. A faulty compressor might make grinding, buzzing, or clicking noises. If you hear these, it’s high time to play detective and track down the source.
Refrigerator Overheating
If the sides of your refrigerator feel hotter than a summer day in the desert, it might be your compressor working overtime. An overworked compressor can cause overheating, which is a red flag that something’s not right. Don’t ignore it!

Diagnosing a Non-Running LG Refrigerator Compressor
You’ve spotted the signs, and you suspect the compressor. Now what? It’s time to put on your detective hat and start the investigation. Remember, folks, safety first! Unplug your refrigerator before beginning any checks or tests.
Checking the Thermostat
The thermostat in your LG refrigerator is like the boss of the operation. If it’s not working properly, it won’t send the signal to start the compressor, even if everything else is fine. So how do you figure out if it’s the thermostat causing the silent treatment?
How to Identify Thermostat Problems
First, you need to check if the thermostat is set correctly. If it’s not set to a cooling mode, then your compressor won’t have any work to do! If the settings are correct but you’re not getting any cold air, your thermostat might just be the villain of this story.
Testing the Thermostat with a Multimeter
If you have a multimeter handy (don’t worry if you don’t, they’re not too expensive and could become your new best friend for home DIY), you can test your thermostat. This website explains how to do it step-by-step, and it’s easier than baking a pie, promise!
Inspecting the Start Relay
You’re probably wondering, what on earth is a start relay? Let me explain. The start relay is like the pep squad for the compressor. It helps kickstart the compressor into action. If it’s faulty, the compressor might refuse to start or might not run properly. To diagnose this, you’ll need to take a look at the start relay itself.
Understanding the Function of a Start Relay
Think of the start relay as a personal trainer for your compressor. It gives it a good shake and gets it going. It does this by boosting the compressor motor’s windings momentarily until the motor runs properly. Just like how a personal trainer might give you an initial push at the gym until you find your rhythm.
How to Test the Start Relay
Testing the start relay isn’t as daunting as it sounds. Again, you’ll need your trusty multimeter (told you it would come in handy!). But remember, safety first. Always unplug your refrigerator before attempting any repairs.
The start relay is usually located at the back of the refrigerator, attached to the side of the compressor. To get to it, you’ll need to remove the back panel of your fridge. This typically involves removing a series of screws, but the process can vary slightly depending on your specific model.
Once you’ve located the start relay, you’ll need to remove it from the compressor for testing. It should pull right off, but be gentle to avoid causing any damage. With the start relay in hand, give it a little shake. If you hear a rattling noise, this could be a sign that the start relay is faulty. A functioning relay should not make any noise when shaken.
For a more precise test, you’ll need a multimeter. Set your multimeter to the lowest setting for Ohms of resistance, then place one probe on the start relay’s common terminal (usually labeled “S”) and the other on the start terminal (usually labeled “M”). If your multimeter does not show a reading, or if the reading is far off from the relay’s specified range, this is a strong indication that your start relay is faulty and may need replacement.
Again, it’s important to mention that if you’re not confident or comfortable performing these steps yourself, it’s always wise to call a professional technician. They’re trained to handle these tasks safely and efficiently, and it could save you from the stress of doing it yourself.
Evaluating the Compressor Motor
Now we’ve arrived at the big player – the compressor motor. If you’ve checked everything else and they all seem fine, it’s possible that the compressor motor itself is the issue. But don’t panic just yet. There are ways to check this too.
Signs of a Bad Compressor Motor
If your compressor motor is failing, it might start making unusual noises, or it may overheat. You might also notice that your fridge isn’t cooling as it should. In some cases, a faulty compressor might trip your circuit breaker, causing your fridge to power off. Don’t worry, though; it’s not all doom and gloom. There are ways to deal with a faulty compressor motor, too.
How to Test the Compressor Motor
Testing the compressor motor is a bit more advanced than some of the other troubleshooting steps we’ve discussed, but we’re here to guide you through it. As always, safety comes first. Be sure to unplug your refrigerator before you get started to avoid any electrical shocks. Let’s proceed with the testing.
Once you’ve located the compressor and removed the panel covering it, you’ll see a set of wires leading to it. These wires connect to the compressor via a terminal, which is what we’ll be testing.
Remove the terminal cover on the compressor, and you’ll find three terminals: Start, Run, and Common. Our aim here is to measure the resistance between these terminals. Remember the multimeter we used earlier? We’ll need it again for this step.
Set your multimeter to the Ohms setting. You’ll be taking three readings – between the Start and Run terminals, the Run and Common terminals, and the Start and Common terminals. Note down the resistance values for each of these measurements.
Here’s the important part: the resistance between the Start and Run terminals should be equal to the sum of the resistance between the other two pairs of terminals (Start and Common, Run and Common). If your readings don’t add up, it’s a clear sign that your compressor motor is faulty.
Keep in mind that testing the compressor motor is quite a complex process. If you’re not comfortable with this level of troubleshooting, there’s no shame in calling a professional. After all, it’s their job to solve these kinds of problems, and they have the right tools and experience to do it safely and efficiently.
Looking into the Condenser Coils
Last, but definitely not least, let’s take a look at your fridge’s condenser coils. These guys are responsible for dissipating heat as the refrigerant passes through them. If they’re dirty or damaged, your fridge might not cool properly, causing your compressor to work harder and potentially fail.
The Role of Condenser Coils in Cooling
The condenser coils are like the lungs of your refrigerator. They breathe out the heat that’s taken in from the inside of your fridge. If these coils are dirty, they can’t release the heat effectively, causing your compressor to run longer and potentially overheat.
Cleaning and Maintenance of Condenser Coils
Cleaning your condenser coils is an easy bit of maintenance that you can do to keep your fridge running smoothly. You can use a coil brush or a vacuum to gently clean the coils. Just be sure to unplug your fridge first to stay safe.
What to Do If Your LG Fridge Compressor Is Not Running
