Incorrectly Connected or Faulty Dispenser Correctly connect the ice dispenser to the water supply and if it doesn’t dump ice, call an expert 6. Clogged Water Line Clean the water line to get rid of the clogging 7. Failing Compressor Replace the compressor if the appliance fails to cool or freeze Is A Noisy Fridge Dangerous?
As I hinted earlier, a fridge is rarely quiet. So, you cannot expect it to run silently. Generally, the fridge unit or the refrigerator will make a noise when running.
For example, they’ll produce a low humming sound when the dispenser or ice maker runs. Such a noise only becomes concerning when it’s too loud.
You can also expect your ice maker to make a clicking sound when filling up with water and a brief banging sound when dumping ice. The door will also beep if left open for long as the running compressor produces a low buzzing sound.
But once these sounds become too loud, too weird, and last longer, that’s a cause for concern. It could indicate a major component failure which could mark the damage to your fridge or refrigerator.
That’s why you’ve to learn to listen to your fridge and act when you identify a weird or loud noise that won’t stop, and it starts with a loud humming sound.
Why Is My Fridge Making a Very Loud Humming Noise?
Generally, your fridge or fridge is making a loud humming noise for one of these seven reasons.
1. The Appliance Is Unleveled
Your fridge or refrigerator must be resting on a level surface. If it’s not, it’ll vibrate excessively, and the screws may loosen and make noise.
While the noise may not necessarily be a loud humming sound, sometimes it is. That’s why you should check the appliance’s leveling as the first step.
Fix
Ensure the appliance is stable and uniform. If it’s not, try adjusting its leveling feet or move it to a more solid and even spot. Meanwhile, check if there are any loose screws and screw them back on.
2. The Evaporator Fan Blade Could Be Ice-Obstructed or Damaged
The evaporator fan is an essential part of your fridge cooling function. It aids in absorbing heat and releasing cold air, which it cannot do when the blade accumulates frost.
Usually, ice builds up over time and prevents the blade from turning, and when it tries doing it, it hits the ice, producing a loud humming sound. But still, the noise could be because the blade is damaged, thus unable to spin correctly.
Fix
If the evaporator fan blade is frosted over, the fix is to defrost the fridge. Just unplug the refrigerator and leave its door open for several hours. That’ll defrost the unit naturally, and it’s safer than using a hair blower or heat gun.
Meanwhile, inspect the fan blade for damage. It could be bent, thus unable to spin smoothly and hitting some parts of the appliance.
If it indeed looks damaged, replace it. You’ll need to take down the back panel to access the evaporator fan and perform this troubleshooting.
3. The Condenser or Evaporator Fan Motor Could Be Defective (Refrigerator Making Loud Humming Noise Not Cooling)
Now that we’ve taken down the back panel to inspect the evaporator fan blade, you may as well examine the condenser fan motor and evaporator fan motor for fault.
First, the condenser fan motor dries up the water in the drain pan every cycle. Not only will it fail to do that when it’s defective, but it may also produce a loud humming sound.
When it comes to the evaporator fan motor, it usually makes a low hum when running well, but the buzz gets loud when it’s faulty. That means it’s unable to distribute cold air (fails to cool) by turning on the fan blade.
Sometimes these fans make a loud humming noise because of losing their lubrication and, at other times, due to wearing out.
Fix
If the fan motor is defective, you’ll have to replace it. That means you’ve to inspect it for wear. But first, try to lubricate it if it looks dry. If that doesn’t work and the fan motor won’t rotate the fan blade, replace it.
4. The Condenser Coils Could Be Filthy
The next stop is your fridge’s top part, where you’ll find the condenser coils once you take out the panel. The condenser coils generally help to hasten the cooling and freezing process, but they often fail to do so when they accumulate dust and dirt.
While this does not indicate any serious malfunction, your fridge will make a humming sound or fail to do its job (freezing).
Fix
Locate the condenser coils near the top rear side of your fridge, or use the manual to do it and inspect them for excessive dirt. If they look filthy, clean them using a vacuum cleaner with a brush attachment.
You can also wipe the coils gently with a soft, damp cloth.
5. The Ice Dispenser Could Be Incorrectly Connected or Faulty
While the ice maker makes a low humming sound when running, especially when the ice doesn’t, sometimes the sound could be too noisy to indicate an issue with the ice dispenser and not the ice maker.
It could be that the dispenser is not correctly connected to the water supply or is faulty. So, consider the two issues.
Fix
Ensure the ice dispenser is properly connected to the water supply. If it’s not, connect it properly. While at it, check to see if the ice dispenser is dumping ice. If it’s not, the chances are that the dispenser is faulty, and you should have an expert check it.
6. The Water Line Could Be Dirt-Clogged
The water line needs cleaning from time to time. If you don’t do that, dirt will clog it and obstruct water flow. Once that happens, water will try to force itself and will thus produce a loud humming sound.
Fix
Inspect the water line for dirt clogging and clean it.
7. The Compressor Could Be Faulty
Lastly, if the fridge is still making a loud humming noise up to this point, the problem could be the compressor failing. The compressor is the centerpiece of your fridge and is responsible for compressing the liquid coolant (or refrigerant) and circulating it.
If it’s faulty, not only will the fridge fail to cool and freeze properly, but it may also produce a loud humming sound.
Fix
Consider replacing the compressor as the last option, expressly if the appliance won’t cool or freeze or does it improperly.
GE Fridge Making Loud Humming Noise
Different issues could force the GE fridge to make a loud humming noise. Notable ones are:
An unlevelled surface that causes the refrigerator to vibrate excessively
An iced-over or bent evaporator fan blade that won’t rotate properly
Dirty condenser coil
An incorrectly connected ice maker or a faulty one, in that matter
A blocked water line
Whirlpool Fridge Making Loud Buzzing Noise
Your Whirlpool fridge is making a loud buzzing sound because it’s excessively vibrating (for resting on an unleveled surface) or due to an ice-obstructed or bent evaporator fan blade, failed fan motor, or dirty condenser coils.
So, you must ensure the appliance rests on a stable, vibration-free surface, the evaporator fan blade is spinning correctly, and the fan motor is running. If it’s none of those issues, it could be a failing compressor that needs replacing.
Frigidaire Fridge Making Loud Humming Noise
If your Frigidaire fridge is making a loud buzzing or humming noise, do not forget to perform these checks:
Ensure the refrigerator is resting on a leveled surface – Away from excessive vibrations
Defrost the fan blade if it’s ice-clogged, and if it looks bent, replace it
Ensure the fan motors (condenser and evaporator fan) are running correctly and if they aren’t, replace them
Unclog the water line if it looks dirt clogged
Clean the condenser coil if it’s filthy
Ensure the fridge is doing its job (freezing), and if it does not, check the compressor
