Understanding Refrigerator Compressor Clicking
Oh, the familiar thud of a fridge doing the cha-cha instead of keeping your leftovers chilled. If your refrigerator’s compressor is playing percussion with uninvited clicks, you’re not alone. Let’s get to the bottom of why it clicks and how to end the concert.
Faulty Start Relay Drama
That tiny start relay in your fridge? It’s like a conductor for an orchestra. It’s supposed to kick things off smoothly, but when it’s busted, you’ve got yourself a noise symphony. If it’s on the fritz, it struggles to juice up the compressor, making it clickety-click while trying to get going. Without this electrical boost, the compressor’s like a car stuck in neutral—it makes a lot of noise but doesn’t go anywhere.
Getting a pro in to swap out the missing-in-action start relay is usually the fix here. If this isn’t sorted, get ready for lukewarm milk and melted ice cream because your fridge won’t stay cold without a working compressor (Home Alliance).
Timer Tension
Ever watched a clock fall apart? That’s your fridge’s electro-mechanical timer when it’s worn out. It’s got tiny cogs that can stop working properly over time, ending in a click-click saga. When these little gears lose their teeth or just fall out of rhythm, your timer doesn’t do its job, leaving the compressor in a limbo of clicks and no cool air (Quora).
Thus, when you hear those desperate sounding clicks, it’s your fridge trying and failing over and over to reboot its cooling cycle. If you catch your timer in this mess, calling a repair person might save you from more fridge drama.
The loud click when your fridge kicks on or off? That’s normal—it’s your fridge saying it’s working. But if there are more noises joining in, it’s time to have a pro inspect it (Quora).
Understanding these culprits, the faulty relay or the worn-out timer, helps you silence the noise nuisance from your fridge.

Refrigeration Basics
To really get what makes a refrigerator compressor go clickety-clack, it helps to have a grip on how refrigeration works. It’s kind of a magic trick pulled off using thermodynamic principles and something called the refrigeration cycle.
Thermodynamic Principles
Refrigeration is all about clever science called thermodynamics. According to its First Law, energy in a closed system doesn’t just vanish into thin air. When you squash gas, it gets all hot and bothered. Let it spread out, and it chills right down (Boyd Corporation).
Some cool thermodynamic moves behind refrigeration are:
- Compression and Expansion: Squeeze gas molecules tight, and they party close together. This hypes up their energy and heats them up. But give them space, and they chill out as their energy fades away.
- Phase Change: A liquid’s got a one-track mind; its temperature stays put during boiling or condensation. So when refrigerators play the condensation game, the system cools its heels till the gas goes full liquid (Boyd Corporation).
| What’s Happening | Temperature Moves |
|---|---|
| Compression | Jump Up |
| Expansion | Slide Down |
| Boiling (Phase Change) | Stays Same |
| Condensation (Phase Change) | No Change |
Refrigeration Cycle Overview
This cycle is like the never-ending story of keeping your fridge chill. Here’s how it goes, bit by bit:
- Compression: It kicks off at the compressor, giving refrigerant gas a pressure boost, so it’s hot and heavy.
- Condensation: The hot stuff heads to the condenser, where the outside air cools it into a toasty liquid (Boyd Corporation).
- Expansion: Next stop is the magic valve, letting the hot liquid flow into the evaporator where it gets its chill on.
- Evaporation: Here, the refrigerant is like a sponge, soaking up heat inside your fridge and vaporizing back into gas.
- Back to Compression: The gassy stuff comes back for more at the compressor, over and over again.
This setup yanks heat out of the fridge, keeping your grub nicely cold.

Importance of Cleaning Refrigerator Coils
Alright, so your fridge coils might not be the most glamorous part of your kitchen setup, but boy, do they pull their weight in keeping things chilled and bills in check. Keeping those coils squeaky clean can save you from a whole heap of headaches.
Efficiency Impact
Imagine your fridge running a marathon with a backpack full of rocks. That’s what happens when dirt, dust, and fuzz take over your coils. Keeping them clean ensures your refrigerator isn’t huffing and puffing to keep your ice cream from turning into a puddle, which can lead to:
- Overheating: Coils love to stay chill, not bake in a dust blanket. If they overheat, your fridge’s safety mechanisms could kick in, giving you an unwanted surprise—a fridge that’s on strike until you handle the grime (Quora).
- Reduced Cooling Performance: Blocked coils mean your fridge is working overtime to keep things cool, which isn’t great news for either your groceries or your power bill (AtomicTech).
Inquisitive minds can find out more about typical compressor hiccups on our common issues with refrigerator compressors page.
Energy Consumption Concerns
If you’ve ever muttered unmentionables at your electricity bill after a summer month, dirty coils may be the sneaky culprit. They make your fridge pull double shifts to maintain freezing status, guzzling more power:
- Increased Energy Bills: A hard-working fridge means your dollars are working overtime, too. A quick coil clean can ease the burden on both your fridge and wallet (AtomicTech).
- Potential Compressor Failure: Dirt can be a compressor’s arch-nemesis. Neglected clogs lead to strain and eventually, the dreaded compressor collapse, a costly calamity best left avoided with a simple wipe-down (Quora).
| Issue | Effect on Performance | Potential Outcome |
|---|---|---|
| Overheating Coils | Compressor calls it a day | Touching base with room temperature |
| Reduced Airflow | Fridge works harder, longer and loves your energy supplier | Watching perishables perish |
| Dirty Coils | Compressor grinds till it drops | Budget wrecking repairs |
Keeping coils clean isn’t rocket science but a sure-fire way to keep your fridge humming merrily. A little upkeep spells a huge relief from breakdowns and credit card meltdowns.

Types of Refrigerator Compressors
Have you ever wondered why your fridge hums in the middle of the night or makes a clicking sound? Let’s break down the mystery of those sounds by talking about the heartbeat of your refrigerator: the compressor. There are three main types that keep everything cool inside: reciprocating, rotary, and centrifugal.
Reciprocating Compressors
This kind of compressor is like the workhorse of the fridge world, mostly found in homes. Think of it like a mini piston engine under your fridge’s hood. It squeezes the refrigerant and keeps the cycle of cooling running smooth and steady. You’ll find these guys in various sizes, fitting different temperature needs—hot, cold, or just right.
| Feature | Description |
|---|---|
| Common Uses | Your everyday household fridge and freezer |
| Operating Temperatures | Can handle all things cold, from chilly to icicles |
| Cooling Efficiency | Just right, not too fancy but gets the job done |

Rotary Compressors
These fellas are the sneaky, quiet types you’ll find in home A/Cs and some fancy fridges. Instead of pistons, they use a spinning blade to do their thing—fast and quiet. Perfect for folks who like their ice cream cold but their houses silent.
| Feature | Description |
|---|---|
| Common Uses | Household fridges, A/C units, and those toasty heat pumps |
| Mechanism | Twirl it! A rotating vane blade spins around |
| Noise Levels | Whisper quiet, like a library for cool air |
Don’t let the quiet fool you—they still need a little TLC to avoid getting cranky. Curious about keeping your coil happy? Check out our piece on the importance of cleaning refrigerator coils.
Centrifugal Compressors
A big player in the refrigeration world, these are for the heavy-duty jobs—think supermarket freezers or giant AC systems. These mostly spin things up and use speed to make things cool. It sounds fancy, and it is.
| Feature | Description |
|---|---|
| Common Uses | Big jobs like commercial and large-scale fridge systems |
| Mechanism | Spin to win—using rotating impellers |
| Application Scale | Made for big cooling tasks |
Not your typical home style, but your local grocer’s cans of fruit cocktail are staying chilled thanks to these. Things getting a bit noisy? You might want to dive into how thermostat and relay functions play into it all.
Now you’re armed with the know-how on what makes the cool magic happen in your fridge, whether it’s at your home or on a grand commercial scale. Next time it clicks, at least you won’t be left scratching your head. If clicking persists, maybe check out our bit on faulty start relay explanations for more insight.
Common Issues with Refrigerator Compressors
When your refrigerator starts making clicking sounds, it’s often pointing a finger at the compressor. Trouble with this component can spell chaos for your kitchen chill box. We’ve got the lowdown on these common compressor hiccups and how to handle them like a pro.
Motor Suspension Problems
One of the main culprits behind that annoying clicking noise could be motor suspension problems. Inside the compressor, there are usually 3 or 4 springs holding the motor in place. If one takes a break, the motor might start nudging up against the shell, causing extra racket when starting up or shutting down (Quora). This ain’t music to anyone’s ears.
| Symptom | Possible Cause | Solution |
|---|---|---|
| Clicking noise during start/stop | Motor hitting outer shell | Fix or swap out those springs |
Dealing with this means either easing the spring tension or getting new ones entirely. Not a job for the faint-hearted, so calling in a repair guru might be your best bet to keep things cool.
Thermostat and Relay Function
That thermostat in your fridge has a pretty important job. It tells the compressor when to get to work and when to kick back, all thanks to its trusty sidekick: the relay. If either goes haywire, expect a symphony of clicks.
| Symptom | Possible Cause | Solution |
|---|---|---|
| Loud clicking noise | Thermostat or relay troubles | Test and swap out the faulty bits |
If your thermostat is acting up, it might cause the compressor to be overly ambitious, while a tired relay could struggle to even get it going. Pop in fresh components and you’ll probably find the noise backs off.
While some clicking is par for the course with these machines, if it comes with serious cooling issues, a technician’s magic touch may be needed. And for more chatter on how to tackle noisy household gadgets, snoop around our articles on why the dryer gets noisier or why the freezer hums a tune.
Knowing these common compressor glitches can keep your fridge a well-oiled machine, cool as a cucumber, and living a long, happy life. Regular maintenance and prompt fixes play a huge role in keeping your kitchen companions running smoothly.
Choosing the Right Compressor
Picking out the right compressor is key for getting your fridge to run just right, especially if it has that annoying clicking noise. Two big things to keep in mind are whether to go for an inverter compressor and the importance of getting some professional guidance.
Inverter Compressors Recommendation
Inverter compressors, fancy talk for variable-speed compressors, are top picks because they last longer and save on energy. These bad boys change speed based on how cool your fridge needs to be, cutting down on both power use and noise.
Key Benefits of Inverter Compressors
- Energy Efficiency: They sip power by cruising at different speeds instead of doing that annoying start-stop thing.
- Noise Reduction: The smooth speed shifts make them whisper-quiet.
- Durability: Less clanky, more smooth means a longer-lasting compressor.
