Refrigerator Compressor Keeps Clicking On and Off: Common Causes and Solutions
If you’ve determined that your refrigerator compressor keeps clicking on and off, you’ll want to understand why this is happening and how to fix it. The following subsections provide an in-depth look at common causes and their corresponding solutions:
Electrical Issues
One of the first things to look for is electrical issues. An inconsistent power supply or a loosely connected plug can cause your compressor to act erratically. Here’s how to handle it:
Check the Outlet: Unplug the refrigerator and test the outlet with another electrical device. If the other device works fine, it indicates that the outlet is not the issue.
Inspect the Cord: Look for visible signs of wear or damage on the refrigerator’s power cord. If you find any, replace the cord immediately.
Secure the Plug: Make sure the refrigerator’s plug is securely inserted into the wall outlet. A loose connection can result in intermittent power, causing the compressor to click on and off.
Faulty Relay
The relay is essentially a switch that provides power to the compressor. When this component is faulty, it can cause the clicking sound you’re experiencing. Here’s how to test and replace it:
Locate the Relay: Turn off and unplug your refrigerator. The relay is usually located near the compressor at the back of the refrigerator.
Remove the Relay: Use a screwdriver to remove the relay from its housing.
Shake Test: Shake the relay gently. If it rattles, it’s likely faulty and needs to be replaced. Relays are generally inexpensive and can be purchased from appliance stores.
Install the New Relay: Place the new relay in the same spot and secure it with screws. Plug in the refrigerator and observe if the clicking has stopped.
Overheating
If your refrigerator is not well-ventilated, the compressor can overheat and start clicking on and off as it tries to regulate its temperature. Here’s how to deal with this situation:
Check for Obstructions: Ensure that there are no items blocking the ventilation around your refrigerator.
Measure the Space: For optimal performance, refrigerators generally require at least a few inches of space on all sides for ventilation. Make sure you provide this space.
Clean the Coils: Over time, the coils at the back of your refrigerator may accumulate dust and grime, making them less effective at dissipating heat. Unplug the refrigerator and use a coil brush or vacuum to clean them.
Check the Fan: Some refrigerators have a fan near the compressor that aids in cooling. Make sure it’s operational. If it’s not, you’ll need to replace it.
