Brief Overview of the Fridge Compressor
Think of the fridge compressor as the heart of your refrigerator, its main job being to pump the refrigerant throughout the system, playing a key role in keeping your food chilled and safe.
What Does a Compressor Do?
The compressor takes the responsibility of maintaining the circulation of the refrigerant, making sure it switches between gas and liquid states. This is a crucial process in ensuring the right cold temperatures inside your fridge and freezer.
How a Fridge Compressor Works
Visualize it this way: The compressor pressurizes the refrigerant, turning it into a hot, high-pressure gas. This gas moves through the condenser coils located either at the back or bottom of your fridge, where it sheds off heat and morphs into a cooler liquid. This liquid then journeys into the evaporator coils located inside the fridge and freezer, absorbing heat and cooling down the interior of your appliance.
Understanding the Issue: Why Is My Fridge Compressor Constantly Running?
Now, what could cause your fridge compressor to keep running? The plain truth is – it shouldn’t. Ideally, your fridge compressor should cycle on and off as per the requirement to maintain the set temperature. If it’s running non-stop, something is definitely not right. Let’s dive deeper into the potential causes.
Signs Your Fridge Compressor is Running All the Time
Before we tackle the reasons, let’s first look at how to identify that your fridge compressor is always running. Some signs are more evident than others, but all are worth keeping an eye on.
Unusual Noise
If your fridge sounds like it’s working overtime all the time, it could be the compressor trying to tell you something. Excessive or strange noises from your fridge are often a clear sign that your compressor might be constantly running.
Overheating
Is the area around your fridge feeling warmer than usual? Excessive heat can be a clear sign that your fridge compressor is working too hard and running non-stop.
Rising Energy Bills
Been noticing a sudden surge in your energy bills? A fridge compressor that runs all the time can be a power hog, leading to a significant increase in your energy consumption.
Fridge Not Cooling Properly
If your food is not staying as cold as it should, or if the fridge interior doesn’t seem cold enough, your fridge compressor might be the culprit.
Reasons Why a Fridge Compressor Keeps Running
So, we’ve identified the signs that your fridge compressor is working overtime. But why does it happen? Here are some possible culprits.
Faulty Thermostat
The thermostat controls the temperature inside your fridge. If it’s not working properly, it might be causing the compressor to run continuously.
How to Diagnose a Faulty Thermostat
Is your fridge colder than the Arctic, or hotter than a summer’s day? Does it not respond when you change the settings? These could be signs of a faulty thermostat.
Dirty Condenser Coils
The condenser coils are responsible for dissipating heat from your fridge. If they’re dirty, they can’t do their job properly, which could lead your compressor to work overtime.
How to Identify and Clean Dirty Condenser Coils
Visible dust or grime on the coils? Then it’s probably time for a clean. You can do this with a coil cleaning brush or a vacuum with a brush attachment. Just remember to unplug your fridge first!
Leaky Door Gaskets
The gaskets around your fridge doors create a seal, keeping the cold air in. If they’re leaky or damaged, the cold air escapes and the compressor has to work harder.
Checking and Replacing Leaky Door Gaskets
You can check the gaskets by placing a dollar bill between the door and the fridge. If you can pull it out easily, the seal might not be tight. If this is the case, it might be time to replace those gaskets.
Defective Fan
The fan in your fridge helps to circulate the cold air. If it’s defective, the compressor has to work harder to keep things cool.
Identifying and Fixing a Defective Fan
If you notice that your fridge isn’t as cold as it should be, or if you can’t hear the fan running, you might have a defective fan. This might require a professional to fix, but it’s worth checking out.
Why a Freezer Compressor Runs Continuously
Now let’s switch gears a bit and talk about the freezer. Why might your freezer compressor run continuously? Let’s explore some reasons.
Overfilled Freezer
Believe it or not, having too much stuff in your freezer can cause the compressor to run all the time. The cold air needs space to circulate, and if it can’t, the compressor has to work harder.
Incorrect Temperature Settings
Setting your freezer to the wrong temperature can cause the compressor to run more than it should. It’s best to check the manufacturer’s instructions for the optimal temperature setting.
Damaged Door Seal
Just like with your fridge, a damaged door seal in your freezer can let cold air escape, making the compressor work overtime.
Aging or Faulty Components
As your freezer gets older, some components might start to fail. This can lead to the compressor running continuously.
Risks of a Fridge or Freezer Compressor Always Running
So why does it matter if your fridge or freezer compressor runs continuously? Surely, it’s just doing its job? Well, not exactly. There are several risks and downsides to a constantly running compressor.
Increase in Energy Consumption
Your fridge and freezer are among the biggest energy consumers in your home. If the compressor is always running, it’s using more power than it should. This can lead to higher energy bills – something nobody wants.
Shortened Lifespan of the Appliance
Like any machine, a fridge and freezer have a certain lifespan. Constantly running the compressor can wear it out faster, shortening the lifespan of the appliance. This could mean you have to replace it sooner than you’d like.
Potential Damage to Other Components
When the compressor is working overtime, it can cause other components in the fridge or freezer to work harder too. This can lead to additional wear and tear, and potentially damage other parts of the appliance.
Increased Risk of Food Spoilage
If the compressor is constantly running, it might not be maintaining the right temperature inside the fridge or freezer. This could increase the risk of food spoiling, leading to waste and potential health risks.

What to Do When Your Refrigerator Compressor Runs Constantly
Okay, we’ve identified the issue, explored the reasons, and understood the risks. Now, what can you do if your refrigerator compressor is running all the time?
Do-It-Yourself Fixes
Firstly, don’t panic. There are some things you can check and fix yourself. Let’s take a look at these DIY fixes.
Checking and Adjusting the Thermostat
Check if your thermostat is set to the right temperature. If it’s set too high or low, try adjusting it to the recommended setting. If this doesn’t work, you might need a new thermostat.
Cleaning the Condenser Coils
If your coils are dirty, give them a good clean. Remember to unplug your fridge first for safety.
Inspecting the Door Seals
Check the door seals for any leaks or damage. If they’re not sealing properly, you might need to replace them.
When to Call a Professional
If you’ve tried the above and your compressor is still running continuously, it might be time to call in a professional. They can diagnose and fix the issue, saving you time and potentially a lot of frustration.
