Your refrigerator is one of the most reliable appliances in your home. It’s also one of the noisiest. Refrigerators produce a constant humming noise as part of their normal operation, and you don’t need to be worried if you hear it coming from your appliance. The hum that your refrigerator makes is caused by the flow of coolant through the system, which can create a variety of sounds. Read on to learn more about why is my refrigerator making a loud humming noise.
Why Is My Fridge Making A Loud Humming Noise?
The loud humming noise coming from your refrigerator may be due to a variety of issues. The first thing you should do is check the entire unit for any loose or damaged parts. If any parts are loose or damaged, you will want to replace them before attempting to fix the problem.
The Reason Why Your Fridge Makes A Humming Noise?
The Fan Is Broken
If you’ve just replaced the motor of your refrigerator, it’s possible that the fan has broken. If this happens, then the condenser will not work properly and you will have to replace the entire device. If your fan is broken, then you will most likely hear a humming sound from the inside of your fridge. However, this sound will be constant and may get louder when you open the door to your refrigerator. If you’re hearing a humming noise from inside your fridge, then the first thing you should do is to check that the fan is not broken. If the fan is broken, then you will have to replace it as quickly as possible because a broken fan will cause your fridge to overheat and start rusting.
The Motor Has A Problem
If the noise coming from your refrigerator is loud, but the hum is constant, then it’s possible that the motor has a problem. If this happens, then you should replace the motor as soon as possible because a faulty motor will cause the fridge to overheat. A faulty motor will be very loud and will hum at a constant volume. However, a broken motor will also cause the fridge to stop cooling, so if the motor is humming loudly, but the fridge does not seem to be cooling down, then the motor has probably broken.
The Humming Noise Comes From The Evaporator Coil
In addition to the condenser, every fridge has an evaporator coil. This device is responsible for removing the warm air within the fridge and replacing it with cool air that comes from the outside. The evaporator coil transfers the warm air to the outside air through a cooling fan. The fan is responsible for the humming noise that you can hear when you’re standing with the fridge door open. If the noise is constant and loud, then the cooling fan may have a problem. If this happens, then you will have to replace the cooling fan as soon as possible because a faulty cooling fan will cause the fridge to overheat.
Your Fridge Is Too Close To Another Appliance
If you’ve just moved your fridge, and now it makes a humming noise that it didn’t make before, then you may have put it too close to another appliance. For example, you should never, ever put your fridge directly next to your stove because the stove is one of the loudest appliances in your home. When a stove is turned on, it makes enough noise to wake people up in the middle of the night. If the stove is too close to your fridge, then the humming noise from the stove will be transferred to your fridge and you will hear it making a humming noise. This type of humming noise is annoying, but it’s also a sign that you need to move your fridge.
There’s A Defect In The Electronic Brain
We’ve already discussed the reasons why a fridge makes a humming noise, but there’s one more issue that can cause your fridge to make a humming noise and that’s a defect in the electronic brain. The electronic brain is responsible for managing the cooling and defrosting systems inside your fridge. When the electronic brain breaks, it can cause your fridge to make a humming noise. However, like a broken fan or motor, a broken electronic brain can also cause your fridge to stop cooling. If your fridge starts cooling less efficiently, or if your fridge starts making a humming noise that it didn’t make before, then there’s a very good chance that your electronic brain has broken.
How To Fix Humming Fridge?
Check the condenser coil
The condenser coil is the part of your refrigerator that regulates the temperature inside by removing heat. If it’s clogged up with dust, grease, or food particles, it affects the performance of your fridge by making it work harder, which may cause it to be louder. To check this, first unplug your fridge, open the back panel, and look for the condenser coil that’s located on the back wall of your refrigerator. Then use a vacuum cleaner to clean the coil. If you see that the coil is covered in dirt, clean it up as best as you can, or if it’s totally clogged, you might have to clean it with a brush. If cleaning the coil doesn’t solve the problem, it might be time to call a professional.
Clean out your fridge
You might think your fridge is clean, but a quick check behind the drawers and bins will reveal otherwise. You may find a lot of dust and grime, along with some old food items. That can cause the compressor to overwork and make your fridge louder. The best way to manage this is to clean out your fridge regularly. If your fridge is humming, you may also have a persistent odor. The best way to get rid of that odor is to clean out your fridge, including the back wall, drawers, and bins. You can also wipe down the walls with a disinfecting cleaner and a soft cloth. If the odor persists after cleaning the fridge, you may have a food item that has gone bad, or there could be a problem with your fridge’s thermostat. If you’re not sure which one it is, call a professional.
Check the compressor
The compressor is the most common part that breaks down in a fridge. While they’re designed to last 10 years or longer, they can be damaged by power surges, a lack of maintenance, or if they run too often. To check if it’s the cause of your humming fridge, you can unplug your refrigerator’s power source, unplug the fridge, too, then lift up the fridge and check if the compressor is making any unusual noise. If you find that your refrigerator is humming and the compressor seems to be making a lot of noise, it’s likely that it’s worn out and will need to be replaced. This is something you should call a professional for since it’s dangerous to attempt to work on a compressor.
Change your door seal
A worn or damaged door seal might be causing your humming fridge. To check if this is true, first, unplug your fridge and then lift up the fridge door. If the door seal is worn out and looks wrinkled or torn, you’ll know you need to replace it. A good seal will help keep the cold air inside the fridge, and a bad seal will let the cold air out. Replacing the seal is an easy fix, though you’ll need to shut off your water supply to the fridge while you do it. You can use a rubber seal repair kit to fix the seal and stop the humming noise. If replacing the seal doesn’t solve the problem, you might have a broken compressor, which is something you should call a professional to take a look at.
Rotate your fridge’s position
If you’ve changed everything else, you can try rotating your fridge’s position. The humming noise you hear might be caused by vibrations that are caused by your fridge being placed on a hard surface, such as a tiled floor. If you place it on a rug, you might notice the humming stops. Before doing this, you should also check your fridge’s position. Make sure that it’s not placed too close to a wall, as that can affect its airflow, and cause it to be louder. You should also avoid placing it in direct sunlight, as that can make it hotter inside, which can also cause it to be louder. If none of these work, call a professional, as these may be signs of a bigger problem.
Conclusion
If your refrigerator is making a loud humming noise, it may be an issue with one of the system’s parts. While the humming sound is not harmful and does not pose a threat to your health, it may be a sign that there is a more serious issue that needs to be addressed by a professional. If you are experiencing noise from your refrigerator, it is important to identify the source of the noise. Once you know what is causing the noise, you will be able to take the appropriate steps to fix the problem.
