Nothing worries you more than unexpected refrigerator troubles when summer is just around the corner. Especially if your Refrigerator making a knocking sound. If that’s the case, now is the time to figure out what’s causing the problem, or it could end up costing you a fortune.
But don’t worry, we’ve got you covered, from the first warning signals to possible solutions. The compressor or condenser fan is the most likely source of knocking noise in your refrigerator. This is usually caused by a buildup of dust in the fan, which reduces air movement and causes a banging or clicking noise.
Probable causes
Before we go into how to start fixing this problem, let’s have a look at some of the most common causes:
Condenser fan motor or blade
Try to figure out where the noise is coming from the next time your refrigerator makes a banging noise. If the noise emanates from the back or bottom of the refrigerator, the condenser fan motor or blade is most likely to blame. You may need to remove the panel to get to the condenser fan motor, which takes only a few seconds.
After that, you may see if the fan blades need to be cleaned; if they don’t, you’ll need to look at the motor. If the knocking noise is coming from the motor, this is the first sign of a faulty motor. Fortunately, such motors can be replaced, so you won’t have to buy a new refrigerator.
Evaporator fan motor or blade
Evaporation is one of the most important refrigeration processes. When the fridge door opens, you’ll hear a knocking sound if it’s broken. This requires the same technique as before, ensuring that the blades are clean or purchasing a new motor.
The compressor
To be clear, the noise coming from the back of the refrigerator could be caused by a variety of things. This could be a condensing mechanism or a compression system that isn’t balanced. It is critical to seek professional assistance with this one.
Circulation of refrigerants
With all of these possible explanations, we can’t miss the most obvious one. This is due to the refrigerant, which is rather typical. You won’t need professional assistance because Freon goes through compressors and condensers as it transitions from gas to liquid. That is how the knocking sound arises, which at first appears to be scary.
We recommend that you ignore this knocking sound if it isn’t overly loud and your refrigerator’s cooling levels aren’t declining.
Water hammers
Water hammers may appear intimidating, but they are simple to use. When water flowing through pipes is forced to stop or shift course, it causes water hammers. When a tap is turned off or an appliance’s valve closes, for example. This causes a loud knocking or “hammering” sound and can cause damage if left untreated.

How to determine if your refrigerator compressor is making a knocking noise
Let me provide a few pointers to assist you in diagnosing the problem on your own.
- Step 1: First and foremost, you must determine where the knocking sounds originate. It’s most likely a leveling issue if your refrigerator makes knocking noises from the outside or behind the panel.
- Step 2: Get a helping hand and tilt the refrigerator backward to make accessing the front legs simpler. Check to see if they’re unequal, and if so, even them out.
- Step 3: Finally, return the refrigerator to its original position. Whether the knocking continues, check to see if the compressor is loose and tighten the nuts using a screwdriver.
Conclusion
Let’s wrap up this discussion on a positive note: the knocking sounds aren’t always alarming, and it’s a good idea to wait for a little to see if it continues. In the vast majority of cases, the noise originates in the compressor or condensing system. Above all, leveling the refrigerator’s front legs can be a simple remedy.
If the knocking continues after you’ve tried all of the offered remedies, you might want to consult an expert. See more useful articles at my website blog2success.net.
