Fridge Making Clicking Noise? 6 Common Problems and How to Fix Them

1. Normal Functionality

To start, it’s important to know that some clicking sounds from your refrigerator are completely normal. Various internal components, like switches, activate and deactivate as part of regular operation. Additionally, when the defrost cycle kicks in, the movement of refrigerant through the evaporator coils can produce slight ticking noises. These sounds are typically quiet, occur intermittently, and shouldn’t be disruptive.

The Solution

In this case, no action is required. If you want reassurance, an SD Appliance Repair professional can inspect the unit to rule out any hidden problems, but otherwise, there’s nothing to worry about.

2. Ice Maker Not Connected to Water Supply

If your ice maker is turned on but not connected to a water supply, it may produce a clicking sound when attempting to fill it with water. On the other hand, if it is connected and still making clicking noises, a malfunctioning component could be preventing it from producing ice properly.

The Solution

To eliminate the clicking sound from a disconnected ice maker, simply switch it off by adjusting the metal arm that controls its operation. If the ice maker is active, occasional clicking is expected. However, if the noise is accompanied by performance issues or leaks, it may be time to have a professional inspect or replace the unit.

3. Faulty Start Relay

The start relay in your refrigerator controls the power supply to the compressor, ensuring it runs efficiently. If the system detects an overload, the relay will shut off power as a protective measure. When the start relay malfunctions, it may continuously click because it mistakenly senses an overload while the fridge attempts to cool. This can result in frequent clicking sounds before the compressor engages, or in some cases, the refrigerator may struggle to maintain a cold temperature.

The Solution

The ideal solution is to replace the switch that controls power to the compressor. Since this involves electrical components, it’s safest to have a professional handle the repair.

4. Evaporator Fan Issues

A rapid, subtle clicking sound may indicate a problem with the evaporator fan. This could be due to a malfunction or ice accumulation interfering with its operation.

The Solution

You have the option to replace the evaporator fan on your own or seek professional assistance for the job. Additionally, cleaning the evaporator coils is recommended to help prevent future ice buildup.

5. Defrost Timer Switch

If there’s a problem with the defrost timer switch, it may produce clicking sounds when activating the defrost cycle. This type of clicking typically occurs once or twice a day. If this issue arises, you might also notice excessive frost accumulating in your refrigerator or freezer.

The Solution

To replace the electrical switch, it’s best to hire a qualified SD Appliance Repair professional for the job.

6. Failing Compressor

A potential cause of clicking sounds from your fridge could be a malfunctioning compressor. If the compressor is damaged internally, it might produce clicking noises. Additionally, the start relay may click as it attempts to power up the faulty compressor.

The Solution

If your fridge is relatively new, it’s best to hire a professional to replace the compressor. However, if the appliance is old and approaching the end of its lifespan, replacing the entire unit might be a more cost-effective solution in the long term.

When to Call a Pro

For simple tasks like turning off a disconnected ice maker that’s clicking or replacing a fan that’s easy to access, you might be able to handle the repairs yourself. However, for anything more complex, it’s safest to contact a professional. Many fridge parts involve electrical elements, which can be hazardous to fix, particularly since they’re near water sources like ice maker lines and defrosting areas. To ensure the job is done correctly and safely, it’s best to reach out to a local repair service.
