Why Isn’t My Oil Diffuser Misting? Problems and Solutions

Whether you have a small personal oil diffuser or a large aromatherapy oil diffuser for your home, there may come a time when it just isn’t working as it should.

Oil diffusers must mist to spread the fragrance throughout the room and cover up any unwanted smells.

When they don’t mist properly, that is when problems can occur. If your oil diffuser isn’t misting enough, you will notice right away because of the lack of lingering fragrance in the room.

There are several reasons why this could be happening but rest assured there are solutions to each of them.

Check out these common problems and solutions regarding your essential oil diffuser not misting.

Your coils are dirty

Probably the most common reason why your oil diffuser isn’t misting is that the coils are dirty.

When you use an oil diffuser, the oils sit in a small area (normally on top of the water chamber) and they heat up.

Once they are heated, the oils turn into tiny particles that travel through the air. As they travel through the air, they cool down and form drops of moisture that fall back down to the coil and the water chamber below.

If the coils are dirty, then the drops that fall back into the water chamber won’t be oil.

They will be dirt and dust. This will cause your diffuser to mist heavily at first because the water chamber will be dirty. Once the water chamber runs clear, the misting will taper off.

Unfortunately, you will need to clean the coils on your oil diffuser to remedy this problem.

Your oil diffuser has not been calibrated

Another common reason why your oil diffuser isn’t misting as it should is that it has not been calibrated.

Or, it has been wrongly calibrated

You may have noticed that certain oil diffusers mist a lot more than others. The reason for this is that the oil diffusers have a mist control knob that you can use to control the amount of misting that it does.

You may have turned the knob all the way to the maximum setting and never noticed it.

Fortunately, this is an easy fix.

Simply turn the knob down a notch and you will notice that your oil diffuser starts misting at a normal level.

The tank doesn’t have enough oil

This one goes along with the previous problems but occurs when you don’t have enough oil in the tank. When you put in the right amount of oil, the oil diffuser will mist at a normal rate. If you don’t put enough oil in the tank, then it will mist heavily at first and then taper off.

The reason for this is that the diffuser needs to make up for the lack of oil in the chamber by misting more. Once there is enough oil in the tank, then the diffuser will mist normally.

To try to prevent this from happening, make sure that you put the right amount of oil into the tank.

If you don’t put enough, the diffuser will mist heavily until you refill it with the proper amount.

You are using the wrong type of oil

If you are using the right amount of oil and cleaning the diffuser regularly and it still isn’t misting, it could be because you are using the wrong oil. There are many different types of oils that can be used in an oil diffuser. Some of these oils are great for scent while others are good for things like fighting bacteria.

If you are misting an oil that is supposed to repel bacteria, you won’t be missing very much at all.

Other oils might be too thick and they won’t mist properly either. If you are misting the wrong oil, you will notice that the diffuser is either misting too much or not misting enough.

If you are using the wrong oil, you will need to switch to a different type of oil that works properly.

The mist Timer is set too short

If you are using the right amount of oil and cleaning and calibrating your diffuser, then the mist timer could be the culprit.

The mist timer is the knob on your diffuser that controls the length of time that the mist is dispersed.

If you have the knob set too low, then your diffuser will mist for a very short period of time.

This could lead to your not misting enough to cover up any unwanted smells in the room. If you have your timer set too low, then all you need to do is turn it up.

Turn up the knob and you will notice your diffuser misting properly again.

The mist controller is not working

The mist controller is the knob that is on the side of your diffuser. It is used to control the misting and turn your diffuser on and off.

This knob could be broken and not working properly which is why your diffuser isn’t misting as it should.

If this is the case, then the only way to fix it is to replace the knob. You can go and buy a new one at any hardware store or you can call the manufacturer and get a new knob.

The unit Isn’t getting enough power

If you have tried all of the above solutions and your diffuser isn’t misting, it may be because your unit isn’t getting enough power.

This is usually the problem when you have bought a cheap diffuser and it doesn’t work as it should. There are certain cheap diffusers that don’t have a high enough voltage and they can’t mist properly.

The ideal solution here is to check the connections between the diffuser and the power source.

Ensure that it is properly connected.

There is something wrong with the device itself

Sometimes there might be something wrong with your oil diffuser itself. If you have cleaned the coils, calibrated the device, and put the proper amount of oil in the tank and it is still not misting, then it might be that there is something wrong with the device.

There could be something blocking the misting ports or there could be a loose wire inside.

Whatever the problem is, it needs to be fixed by a professional or you run the risk of causing more damage to the device and voiding your warranty.

Or just buy a new essential oil diffuser.


When you are using an oil diffuser, it is important to make sure that it is working properly. If it isn’t misting, there is a problem that needs to be addressed.

And if one of the solutions is a replacement, ensure that you get it from a reliable source.
