Refrigerator Making Clicking Noise and Not Cooling
A clicking or ticking sound combined with a refrigerator that isn't cooling is a classic symptom of a specific problem — most commonly a failing start relay or a struggling compressor. Here's what's happening and what you should do.
What Causes the Clicking Noise?
1. Faulty Start Relay
The start relay is a small component that helps the compressor start. When it fails, it sends power to the compressor, which tries to start, fails, and then clicks off — creating a click-click-click pattern every few minutes. This is the most common cause of a clicking, non-cooling fridge.
How to test: Unplug the fridge, locate the start relay on the side of the compressor, remove it, and shake it. If you hear a rattling sound, the relay has failed and needs replacement. A new relay costs $20–$50 and a technician can swap it in under an hour.
2. Compressor Failure
If the start relay is fine but the clicking and cooling problem persists, the compressor itself may be failing. Compressors are the most expensive component in a refrigerator and cost $300–$600 to replace — sometimes making replacement the better option for older units.
3. Overload Protector Failure
The overload protector prevents the compressor from overheating. When it fails, it repeatedly trips and resets, causing a clicking sound.
4. Low Refrigerant
Though less common (since refrigerators are sealed systems), a leak can cause the compressor to work harder and overheat, creating similar symptoms.
Samsung Freezer Ice Buildup at Bottom
Samsung refrigerators have a known issue with ice forming at the bottom of the freezer compartment. This is typically caused by a defrost system failure — the drain becomes clogged with ice, causing water to pool and refreeze. A technician can clear the drain and recalibrate the defrost cycle.
LG Refrigerator Not Cooling
LG fridges have a known linear compressor issue covered under an extended warranty. If your LG fridge isn't cooling, check whether your model is covered. Symptoms include a quiet compressor that runs constantly without cooling effectively.
Fridge Door Won't Stay Closed
A refrigerator door that won't seal properly wastes energy and can cause the compressor to run continuously. The most common cause is a worn or damaged door gasket (the rubber seal around the door). Test it with a dollar bill — close the door on it and pull. If it slides out easily, the gasket needs replacing.
