A dehumidifier is necessary if you want to be more pleasant and comfortable during the summer and spring seasons. A dehumidifier may significantly reduce humidity and make your home more comfortable to live in.
Even though dehumidifiers are silent, they occasionally produce noises that can be loud or excessive in some circumstances, making it impossible to sleep or work in a peaceful environment. This commonly happens when you don’t clean and maintain your dehumidifier on a regular basis.
Below we have a complete guide on How to fix a noisy dehumidifier. Have a look!
Why Is Your Dehumidifier Making A Noise?
A dehumidifier can make noises due to various reasons, and most of those reasons are directly related to cleaning and maintenance. Since if the dirt gets inside the filters or blocks the fan movement, the dehumidifier will eventually create weird noises that will disturb you all the time.
Apart from that, if the dehumidifier’s air intake is blocked, it will also lead to noise creation. Since when the air passes through the blocked air vent, it causes buzzing, which leads to noise and vibration.
Another reason why your dehumidifier is making noises is that it has loose screws or bolts or some other parts which are causing it to vibration and make noise as well.
How to Fix A Noisy Dehumidifier? (Complete Guide)
There are several steps you need to try out in order to fix your noisy dehumidifier because there is no single reason which causes noise in a dehumidifier.
Start by inspecting the dehumidifier placement. If your dehumidifier is sitting on an uneven surface, it will create a rattling sound or vibration while operating. You need to make sure that the dehumidifier is placed on an even surface.
You can ensure this by adjusting the legs of the dehumidifier if it has adjustable legs. If the dehumidifier does not have adjustable legs, you can use an object like a coin, book, etc., to adjust and make the surface even for all four legs of the dehumidifier.
Tighten the Parts
If adjusting the legs or placing the dehumidifier on a leveled surface does not fix the dehumidifier noise creation problem, you need to check the other components of the dehumidifier.
Start by inspecting all the nuts and screws, as loose nuts and screws can create rattling sounds and vibration as well. Make sure to look underneath the dehumidifier for any loose screws or components.
Also, ensure that the lid is tight and firm in place and not making any noise. Furthermore, shake the dehumidifier a few times to ensure that there are no loose components inside the dehumidifier that are producing the noise.
Repair or Replace the Dehumidifier Compressor
All dehumidifiers include a compressor unit that functions similarly to an air conditioner compressor. The dehumidifier compressor eliminates moisture from the air by compressing the refrigerant gas into a high-pressure, high-temperature gas that flows through the dehumidifier coils.
When hot gas passes through the coil, it emits heat, which generates moisture in the surrounding environment and collects it on the coils.
If the dehumidifier compressor is faulty or damaged, the dehumidifier won’t be able to run effectively and smoothly. Moreover, it may start creating noises whenever you turn it on.
If the dehumidifier compressor is causing the noise, then you need to replace the compressor completely. We recommend that you get it replaced by a specialist.
Clean the Filter
Most dehumidifier comes with an air filter that ensures you breathe in a clean environment. However, with the overuse of the dehumidifier and no maintenance, it gets clogged and starts naked a humming sound.
If you hear humming or buzzing coming from your dehumidifier, you must clean or replace the filter. If you are not sure how to replace the filter in a dehumidifier, you must contact customer service for assistance.
Check Fan Movement
The fan sometimes does not move, or if it does, it makes noise because the blades create friction due to dust buildup inside the dehumidifier.
If this is the case, you may need to replace the fan entirely or clean the dehumidifier from the inside to ensure that the fan moves freely without touching the housing.

Frequently Asked Questions:
How to Reduce the Fan Noise in A Dehumidifier?
While there is no direct way to lessen noise, you can reduce the fan’s speed if it is adjustable. If this does not minimize the noise, inspect the fan’s internals to ensure they are functioning properly. You should clean it if there is dust accumulation.
How to Fix Excessive Vibration in Dehumidifier?
If your dehumidifier is creating excessive vibration, you need to check its fan. Make sure the fan blades are working smoothly, and there is no dust around them.
You may also check the blade shape and ensure it is in the correct shape. Since if the fan blades are bent, it will lead to excessive vibration, which will eventually create noise in your dehumidifier.
When Should I Replace the Dehumidifier Filter?
Depending upon the brand recommendation, you can change the dehumidifier filter. Most of the dehumidifier filters should be replaced after every 12 months or 1 year of use to ensure safety.
How Often Should I Clean My Dehumidifier?
Ideally, you should clean the dehumidifier once a month or every two weeks, depending on the air quality of your home. Make sure to clean the tank and dust from inside as well.
What Should I Do If My Dehumidifier is Leaking Water?
If your dehumidifier is leaking water, then there are several things you need to check and fix:
1. Turn off the dehumidifier and remove the water collection bucket or drip tray.
2. Next, check the water tank and hose for any damage, clogs, or kinks.
3. Fill the dehumidifier water tank and check if it is leaking.
4. You can use waterproof adhesive tape to seal any small leakage in the hose or tank. But it is a temporary fix; you may need to replace the component later.
5. Besides that, check the switch and drain reservoir to ensure everything is working properly. You can use a volt-ohm meter to check the switch and unclog the drain if required.
6. Lastly, make sure to adjust the dehumidifier placement so that water flows downward without spilling.
So that’s how to fix a noisy dehumidifier in your home. If this is your first time using a dehumidifier, you should be aware that it creates some noise due to fan movement, air intake, exhaust, and air compressor noise.
However, if your dehumidifier is creating unusually loud or bothersome noises, you should investigate. Check various components such as the nuts and bolts, clean the fan motor and blower wheel, and place them on an even surface for smooth operation.
