Understanding Refrigerator Compressor Noise
Before we dive into the different ways to quiet a noisy refrigerator compressor, it’s important to understand the source of the noise.
The compressor is the heart of your refrigerator and is responsible for circulating refrigerant through the system to keep your food cool.
The compressor can make noise for several reasons, including loose parts, worn-out components, and a dirty or clogged condenser coil.
A typical refrigerator compressor produces around 30–40 dB of noise, which is similar to the sound of a whisper or a quiet library. If your refrigerator compressor is producing more than 50 dB of noise, it’s considered loud and may need to be repaired or replaced.
3 Causes of a Noisy Refrigerator Compressor
There are several reasons why your refrigerator compressor may be making noise. Here are some common causes:
1. Loose parts
One of the most common causes of a noisy refrigerator compressor is loose parts. Over time, the screws and bolts that hold the compressor in place can become loose, causing the compressor to vibrate and make a noise.
2. Worn-out components
Another common cause of a noisy refrigerator compressor is worn-out components. The compressor motor mounts, which hold the compressor in place, can wear out over time and cause the compressor to vibrate and make noise.
3. Dirty or clogged condenser coil
A dirty or clogged condenser coil can also cause your refrigerator compressor to make a noise. The condenser coil is responsible for dissipating heat from the refrigerant, and if it’s dirty or clogged, it can cause the compressor to work harder and make more noise.

4 Steps to Diagnose a Noisy Refrigerator Compressor
Before you can fix a noisy refrigerator compressor, you need to diagnose the problem.
Here are some steps to follow:
- Check the tightness of all connections – Check the screws and bolts that hold the compressor in place to make sure they are all tightened securely.
- Test refrigerator components – With the power off, check each component such as the motor mounts, condenser coil, and compressor for signs of wear or damage.
- Look for refrigerant leaks – Check for signs of refrigerant leaks, such as strange odors or oil residue around the compressor.
- Check wiring and capacitors – Inspect the wiring and capacitors connected to the compressor for any visible signs of damage or wear.
Once you have diagnosed the problem with your refrigerator compressor, you can decide whether it needs to be repaired or replaced to reduce noise levels.

Q2: How do you cure a noisy refrigerator?
Ans: You can reduce the noise with sound-dampening curtains, an anti-vibration pad, or an acoustic foam pad. You can also consider upgrading to a quieter refrigerator compressor that produces less than 50 dB of noise.
Q3: How do you clean a refrigerator compressor?
Ans: To clean a refrigerator compressor, you’ll need to turn off the unit and use a dry cloth to dust away any dirt, dust, and other debris that may have built up around the area. Then use a vacuum brush attachment to remove any lint or other particles that are stuck on the fan blades. Finally, use compressed air with a nozzle attachment to blow away any remaining dirt or dust.
Q4: What does a bad refrigerator compressor sound like?
Ans: A bad compressor will usually produce loud hums and buzzes, which can be very loud and persistent. You may also notice strange gurgling or gasping noises coming from the unit as well.
Q5: When should I worry about my fridge noises?
Ans: If your refrigerator is making unusual noises such as rattling, ticking, or popping, or if it’s louder than usual, it’s best to get it checked by a professional.
Q6: How do you lubricate a refrigerator?
Ans: You should always turn off the unit and unplug it before attempting to lubricate a refrigerator compressor. You can then use a high-grade appliance oil such as SAE 10 or SAE 20 and apply it to the moving parts inside the compressor. If performing this task yourself, be sure to read any manufacturer instructions carefully before beginning.
Q7: How to stop fridge vibration noise?
Ans: To help reduce vibration noise coming from your refrigerator, you can place an anti-vibration pad or acoustic foam pad underneath the unit. This will help insulate and muffle the sound of the vibrating compressor. Additionally, you can also adjust the adjustable feet on the bottom of the fridge to level out any unevenness that may be causing vibrations and noises.
Q8: Can a noisy refrigerator be fixed?
Ans: Yes, a noisy refrigerator can usually be fixed with a few simple steps. Firstly, ensure that the refrigerator is level and that all the adjustable feet at the bottom are set properly. You may also want to consider sound-dampening curtains or foam pads to reduce noise coming from the unit. Finally, check to make sure that all parts are clean and well-lubricated as necessary, and replace any older parts with quieter models if necessary.
Q9: Is it normal for the fridge compressor to make noise?
Ans: Yes, it is perfectly normal for a refrigerator compressor to make some noise. However, if the noise is louder than usual or persists, then it could indicate a problem that needs to be addressed as soon as possible. Additionally, any strange noises such as rattling, ticking, or popping should be investigated and rectified as soon as possible.
Q10: Why is my fridge making a loud humming noise?
Ans: If your fridge is making a loud humming noise, it could be due to the compressor motor or fan blade rubbing against something. If this issue is not rectified immediately, it could cause serious damage to your unit. Check the fan blades to make sure they are spinning properly, and check the interior components to make sure there are no obstructions that could be causing the noise. Additionally, an ill-fitting and damaged gasket could be allowing cold air to escape, causing a loud humming noise.
Q11: Why is my fridge making noise but stopping when the door opened?
Ans: This is likely due to a stuck evaporator fan motor. The evaporator fan motor is responsible for circulating the cooled air inside the refrigerator. When the motor sticks, it produces an intermittent noise that will cease when the door is opened. To investigate this issue further, you may need to unscrew and inspect the fan itself or consult a professional technician.
Q12: What kind of lubricant should I use to quiet a noisy refrigerator compressor?
Ans: For the best results, you should use a silicone-based lubricant or WD-40 to lubricate the compressor fan and reduce noise. Avoid using oil-based products, as these may not be as effective in noise reduction.
