Fridge Freezer Making Loud Noise? Your UK Fix Guide
A loud fridge freezer is usually down to one of a few common culprits. It could be something as simple as the appliance not being level, causing vibrations. Or maybe the condenser coils are dirty, forcing the compressor to work overtime. Sometimes, it’s just a fan that's blocked.
The good news? Many of these noises, whether it’s a rattle or a loud hum, are things you can often fix yourself with a few simple adjustments and don’t always mean there’s a major fault.
Why Your Fridge Freezer Is Suddenly So Loud
That sudden, strange noise coming from the kitchen can be alarming. One minute, your fridge freezer is just part of the background hum of your home; the next, it’s making a racket you simply can’t ignore. But before you panic, most of these sounds are symptoms of relatively minor issues.
Often, the noise is just a normal part of the fridge’s operation that has been amplified. For instance, a small vibration can easily turn into a loud rattle if the fridge isn't standing perfectly level. This is one of the easiest things to check and fix yourself.
Common Sources of Loud Noises
Figuring out what kind of sound it is and where it’s coming from is the first step towards getting it sorted. The most frequent culprits behind a noisy fridge freezer usually include:
- The Compressor: This is the engine of your appliance. A constant, loud buzzing might mean the compressor is working too hard, often because dirty condenser coils can't get rid of heat properly.
- Fan Motors: Your fridge freezer has at least two fans – one for the condenser and another for the evaporator. If either gets blocked by dust or a build-up of ice, you might hear a whirring or rattling noise.
- Vibrations: Sometimes, the noise isn't from a faulty part. It could be the drain pan vibrating, or even items inside the fridge rattling against the walls.
It’s reassuring to know that many loud fridge freezer problems don’t actually need an engineer. A bit of simple maintenance and a few adjustments can often bring the peace and quiet back to your kitchen.
By getting to know these potential sources, you're in a much better position to figure out what's going on. You might be surprised to find that many common fridge faults and their solutions are quite straightforward.
Decoding the Noises Your Fridge Is Making
Different noises tell different stories about what's going on inside your appliance. Learning to interpret these sounds helps you move from being worried to taking action. Think of yourself as a noise detective—each sound is a clue pointing you towards the source of the problem. A fridge freezer making a loud noise isn't one single issue; it's a symptom that can have many different causes, each with its own signature sound.
The Buzzing or Humming Sound
A constant, loud buzzing or humming often points to the compressor. While a gentle hum is perfectly normal, an unusually loud one suggests it's working overtime. The main suspect is usually dirty condenser coils, which struggle to release heat and force the compressor to run harder than it should.
This sensitivity to household sounds is more common than you might think. During the COVID-19 lockdowns, noise complaints in England saw a 54% spike, as people at home became more aware of appliance noises. You can find out more from the Chartered Institute of Environmental Health.
Rattling and Vibrating Noises
If you're hearing a rattling sound, the fix could be simple. Often, the noise is just the drain pan underneath the appliance vibrating. It could even be a bottle or jar inside leaning against an interior wall and rattling as the compressor runs.
Pro Tip: Gently pull the fridge freezer away from the wall and check that it’s completely level. An uneven footing is a very common cause of mysterious rattling noises.
Clicks, Squeals, and Scrapes
Sharper sounds like clicking or squealing point to moving parts that may be failing or blocked.
- Sharp Clicking: A repeating click could be a failing starter relay on the compressor. If the noise is from your ice maker, it might be trying (and failing) to complete a cycle.
- Squealing or Chirping: This high-pitched sound often comes from a failing fan motor. A worn-out bearing in the evaporator or condenser fan can cause a distinct squeal.
- Scraping: A scraping sound from the freezer section is likely the evaporator fan blade hitting a build-up of ice, signalling an issue with your defrost system.
Pinpointing the exact sound narrows down the potential culprits. This quick-reference table organises these common sounds and what they likely mean.
Common Fridge Freezer Noises and Their Likely Causes
Sound Description | Common Cause | Potential DIY Fix? | When to Call a Pro |
---|---|---|---|
Loud, Constant Buzzing | Dirty condenser coils or a failing compressor. | Yes, you can clean the coils. | If cleaning doesn't help. |
Rattling or Vibrating | Fridge isn't level, or items are vibrating. | Yes, adjust the feet or rearrange items. | If the sound persists after basic checks. |
Repetitive Clicking | Faulty starter relay or ice maker issue. | Possibly, if it's the ice maker. | If it's the compressor's starter relay. |
Squealing or Chirping | Worn out evaporator or condenser fan motor. | No, fan motors are best replaced by a pro. | As soon as you hear this noise. |
Scraping or Grinding | Fan blade hitting ice due to a defrost issue. | No, this points to a more complex problem. | This usually requires an engineer. |
While some issues are simple fixes, others involve electrical components and are best left to a qualified engineer.
Your First Steps to a Quieter Fridge Freezer
Now that you have an idea of what might be causing the racket, it's time for some simple, hands-on action. Many cases of a fridge freezer making a loud noise can be sorted with a few basic checks.
Before you start, there's one golden rule: always unplug your appliance from the mains. Safety first.
Master the Art of Levelling
An uneven appliance is a common culprit for rattling. If your fridge freezer isn't sitting perfectly level, the compressor's normal hum can be amplified. Grab a spirit level and pop it on top. Most models have adjustable feet at the front that you can screw to tweak the height. A tiny adjustment is often all it takes.
Secure the Drain Pan
Another source of rattling comes from the drain pan, which collects condensation. It can sometimes work itself loose and vibrate. Gently pull your fridge away from the wall to get a proper look. You should see a shallow tray near the bottom. Check if it's securely in place—sometimes it just needs a nudge to clip it back into its housing.
Clear Out the Condenser Coils
Over time, condenser coils get covered in dust and pet hair. When clogged, they can't get rid of heat properly, which forces the compressor to work much harder. This strain is a classic cause of loud humming.
Regular maintenance is your best defence. Taking 15 minutes every six months to clean the coils can reduce noise, improve efficiency, and extend your fridge freezer's life.
Use a long, soft brush or your vacuum's brush attachment to carefully get rid of all the dust. This simple task can make a massive difference. For more tips, see our guide with 5 simple tips for fridge maintenance.
Inspect the Fans for Obstructions
Your fridge freezer uses two fans to move air: the condenser fan (near the compressor) and the evaporator fan (inside the freezer). If either is blocked, you'll hear a whirring or scraping sound.
- Condenser Fan: With the appliance unplugged, check the condenser fan at the back for debris. Carefully clear away anything you find.
- Evaporator Fan: This is behind a panel inside your freezer. A build-up of ice can hit the fan blades. If you see a lot of ice, it could point to a problem with the defrost system.
If the sound is still there after these fixes, it might be time to look deeper at the components.
When It Is Time to Call an Appliance Engineer
While a DIY fix is satisfying, it's important to know when to stop. Some noises are clear warnings of a serious mechanical problem where stepping back is the smartest move. Trying to fix complex components without the right training can lead to more expensive damage or create a safety hazard.
If your fridge freezer is making a loud noise that’s still there after you’ve cleaned the coils, levelled the unit, and checked the fans, the issue likely runs deeper.
Red Flags You Cannot Ignore
Certain symptoms should have you calling a professional immediately. A loud, relentless buzzing or clicking from the compressor area is a major red flag, as this often means it’s on the verge of failing. This is absolutely not a DIY job.
Other serious warning signs include:
- Any unusual smells: A burning or chemical odour points to an electrical fault or a refrigerant leak.
- Excessive heat: If the back or sides feel unusually hot, something is working too hard.
- Poor cooling performance: When the noise is paired with your food not staying cold, the core cooling system is likely compromised.
A noisy appliance can be more than an annoyance; it can be a significant disturbance. In the UK, appliance noise is a recognised source of domestic disruption. Learn more about how domestic noise sources impact UK residents here.

Your Questions About Noisy Fridges Answered
Here are answers to some of the most common queries we get.
Is It Normal for a New Fridge to Be Loud?
Yes, it's common. A new fridge freezer can be noisy for the first day or two. When first plugged in, the compressor and fans work hard to bring the internal temperature down. You might hear gurgling as refrigerant circulates or clicks and pops as parts expand. These sounds should settle down within 24-48 hours. If not, check that the appliance is level.
How Can I Reduce Everyday Fridge Noise?
Beyond fixing faults, you can dampen normal operational sounds.
- Give It Breathing Room: Ensure at least an inch of clearance on the sides and top, and two inches at the back for proper airflow.
- Try Anti-Vibration Mats: A rubber or cork mat underneath can absorb compressor vibrations.
- Check the Contents: Bottles and jars rattling against each other can make a real din. A quick rearrange can work wonders.
Can a Loud Fridge Increase My Electricity Bill?
Absolutely. A loud noise often means an appliance is struggling to work efficiently. If dirty coils force the compressor to run non-stop, it's guzzling more electricity. The same goes for a faulty fan or defrost system. Fixing the source of the noise isn't just about getting peace and quiet; it’s a smart move for your wallet.
