1Clicking every few minutes
The fridge tries to start, the overload trips, and it clicks off. Then it tries again.
How we fix it: We test the start relay and overload first, then the compressor windings.

The problem
What the Compressor Does, and How It Fails
The compressor is the pump at the heart of your fridge. It sits in the back, near the floor. It squeezes refrigerant gas and pushes it through the coils so heat can leave the fridge. When it runs, your fridge cools. When it cannot start, nothing cools.
Here is the good news. Many “bad compressor” calls are really a failed start relay or overload. These are small parts clipped to the side of the compressor. They cost far less than a compressor and can be replaced in under an hour.
Newer fridges, like many LG and Samsung models, use inverter or linear compressors. These are run by an inverter control board. When the board fails, the compressor looks dead but is fine. We test both before we decide.
A true compressor failure means sealed system work. That includes brazing, a new filter drier and a fresh refrigerant charge. We cover that part on our sealed system repair page.
Common causes
Signs Your Compressor Needs Attention
Each sign below has more than one possible cause. That is why testing matters.
2Loud hum but no cooling
The compressor gets power but cannot turn over. A weak start device or a locked compressor can cause this.
How we fix it: We check start current and, if needed, the compressor itself.
3Fridge runs nonstop
A tired compressor may run all day but cannot move enough heat. Dirty coils can cause the same thing.
How we fix it: We measure amps and temperatures. See Condenser Coil Cleaning if coils are the cause.
4Compressor very hot to touch
Heat builds when the condenser fan stops or coils are packed with dust.
How we fix it: We fix airflow first. See fan motor repair.
5Breaker trips when the fridge starts
A shorted compressor or wiring problem can trip the circuit.
How we fix it: We test insulation resistance and wiring safely.
6Inverter error code
Many LG and Samsung fridges show a code when the inverter board cannot drive the compressor.
How we fix it: We test the inverter board. See control board repair.
Before you call
What You Can Check First
These checks are safe and help us diagnose faster. Do not open the electrical cover on the compressor.
Safe checks you can do
- Listen at the back bottom of the fridge for clicking or humming.
- Make sure the fridge is on its own outlet, not an extension cord.
- Feel if air is flowing out of the vent at the bottom front.
- Clean dust off the coils and around the compressor area.
- Give the fridge 4 inches of space at the back for airflow.
- Write down any error code on the display.
Call a pro when
- You hear clicking every few minutes and no cooling.
- The fridge hums loudly but stays warm.
- The breaker trips when the fridge starts.
- You smell burning near the back of the fridge.
- The display shows an inverter or compressor error.
Repair or replace
Compressor Repair vs. New Refrigerator
A compressor job is one of the costlier fridge repairs. Here is how we help you decide.
| Situation | What it usually means | Our advice |
|---|---|---|
| Bad relay or overload | Low-cost part, compressor is fine | Repair. Quick and affordable. |
| Inverter board failure | Board drives a healthy compressor | Repair. Replace the board. |
| Compressor failed, fridge under 8 years | Sealed system job, often warranty-covered | Check warranty, then repair. |
| Compressor failed, fridge 8–12 years | Major repair on a mid-life fridge | Compare. |
| Compressor failed, standard fridge 13+ years | Cost can near a new fridge | Often replace. |
| Built-in luxury fridge, any age | Made to last 20+ years | Usually repair. See built-in repair. |
Warranty tip: many brands cover the compressor for 5 to 10 years, and some LG linear compressors carry even longer coverage. Check your manual or registration before paying out of pocket.

Questions
Refrigerator Compressor FAQs
What homeowners ask us most about compressors.
How do I know if my refrigerator compressor is bad?
Common signs are clicking every few minutes, a loud hum with no cooling, a very hot compressor or a fridge that runs nonstop. A test is needed, because a cheap start relay often causes the same signs.
Can a refrigerator compressor be repaired?
The parts around it, like the relay, overload and inverter board, can be repaired. A failed compressor itself is replaced, which is sealed system work.
Is it worth replacing a compressor on a 10-year-old fridge?
Sometimes. If the fridge is in good shape and the price is well under half of a new one, it can make sense. We give you both numbers.
Why does my fridge click but not start?
That is usually the overload or start relay tripping. It can also be a compressor that is locked up. Testing tells us which.
Is my compressor covered by warranty?
Many brands cover compressors for 5 to 10 years. Check your registration or manual. We can help you find the model and serial number.
Can heat damage a refrigerator compressor?
Yes. Hot rooms, garages and dusty coils make the compressor run hotter and longer, which shortens its life.
