It can be quite concerning when your fridge starts making strange noises, especially if you’re not sure what’s causing them. One common sound that many people hear is a knocking or banging noise. In this article, we’ll explore some of the possible reasons why your fridge is making this sound, and what you can do about it.
Loose Components
One of the most common reasons for a knocking sound in your fridge is loose components. As your fridge runs, it vibrates, and this can cause screws, nuts, and other parts to become loose. Over time, this can lead to a knocking sound as these components move around inside your fridge.
If you suspect that loose components are the cause of the knocking sound, you can try tightening any screws or nuts that you can access. However, if you’re not comfortable working with electrical appliances, it’s best to call in a professional.
Blocked Condenser Fan
Another possible cause of a knocking sound in your fridge is a blocked condenser fan. The condenser fan is responsible for cooling the compressor, and if it becomes blocked, it can cause the compressor to work harder than it should. This can lead to a knocking sound as the compressor struggles to keep up.
To check if this is the cause of the knocking sound, you can try cleaning the condenser fan. This is usually located at the back of the fridge, and can be accessed by removing the cover. Use a soft brush or cloth to remove any dust or debris that has accumulated on the fan blades.
Worn Compressor
If your fridge is making a knocking sound that seems to be coming from the compressor itself, it’s possible that the compressor is worn. Over time, the internal components of the compressor can become worn, and this can cause a knocking sound as they move around.
If this is the case, it’s best to call in a professional as replacing a compressor can be a complex and dangerous process. In some cases, it may be more cost-effective to replace the entire fridge rather than just the compressor.
Uneven Fridge
If your fridge is not sitting level, it can cause a knocking sound as the compressor tries to compensate for the unevenness. Check that your fridge is sitting level on the floor, and adjust the feet if necessary.
Conclusion
If your fridge is making a knocking sound, it’s important to identify the cause so that you can take appropriate action. While some causes of a knocking sound are relatively simple to fix, others may require professional help. By taking care of your fridge and addressing any issues promptly, you can help to ensure that it continues to run smoothly and reliably for years to come.
