Demystifying Why Your Refrigerator Compressor Just Clicks
The clicking sound from a refrigerator compressor typically indicates an attempt to start the compressor that is unsuccessful. This can arise due to a variety of issues such as electrical failures, faulty components, or mechanical defects. Let’s delve into each area to help you troubleshoot the problem.
Refrigerator Compressor Just Clicks Troubleshooting
If your refrigerator compressor just clicks, follow the steps below to troubleshoot the problem.
Safety First
Before embarking on any troubleshooting steps, it’s crucial to unplug the refrigerator to prevent any electrical shock. This ensures a safe environment as you investigate the issue.
Check the Electrical Outlet
Your journey begins with the electrical outlet. First, unplug the refrigerator and plug another small appliance, such as a lamp or a phone charger, into the same outlet. This will let you know if the issue is with the outlet or the refrigerator.
If the other appliance works fine, then your outlet is likely in good shape. If it doesn’t work, the issue might be with your home’s electrical circuitry, and it’s best to consult an electrician. This step is vital because the power source needs to be consistent for your refrigerator to function properly.
Inspect the Power Cord
Next on the list is the power cord, often overlooked yet crucial for electrical supply. Unplug it and inspect it for any signs of wear, tear, or fraying. A damaged power cord can result in power supply inconsistencies, which might cause the compressor to click without starting.
If you spot any damage, consider replacing the cord immediately. If the cord has any loose sections, this can also impact power flow, causing similar issues.
Verify the Start Relay
The start relay acts as a bridge between the compressor and the electrical system of the refrigerator. It helps in kicking off the compressor.
To check the start relay, you’ll need a multimeter. Remove the relay (it’s usually a small box-like structure attached to the side of the compressor), and place the multimeter probes on it, setting the multimeter to the Ohm setting.
If the multimeter shows no continuity, it’s a sign that the start relay is faulty and needs replacement. A malfunctioning start relay cannot send the required voltage to the compressor, causing it to click without starting.

Examine the Compressor Motor
If you’ve reached this point and still haven’t found the issue, it’s time to check the compressor motor. The compressor motor can be a complex component to diagnose. If you gently shake it and it rattles, it indicates that the internal motor might be loose or damaged.
However, replacing a compressor is a costly and complex process, often requiring specialized tools and expertise. If you suspect a faulty compressor motor, it’s best to consult with a professional technician.

Other Potential Issues
If all else fails, there are other, less common issues that could be at play. These include problems with the refrigerator’s thermostat, control board, or capacitors.
If the thermostat is not working, it cannot signal the compressor to start. Similarly, a faulty control board can interfere with the compressor’s functionality. Capacitors store and release electrical energy to help the compressor motor start and run. If they’re faulty, they could be the reason behind the clicking noise.
All these are complex components and it’s advisable to consult a professional for proper diagnosis and repair.
When to Call a Professional
If you’ve checked everything outlined in this guide and your refrigerator compressor is still clicking, it’s time to seek professional help. Dealing with complex electrical and mechanical issues without proper expertise can lead to further complications. Moreover, DIY fixes could void your appliance’s warranty.
