Why Does My Humidifier Keep Turning Off? 3 Vital Checks

Why does my humidifier keep turning off? And what can I do about it?

This is the dilemma that many people find themselves in at one time or another. Your appliance works just fine and then one day, it starts turning itself off, without lowering the humidity.

On this blog, we have discussed many humidifier problems before, including ultrasonic humidifiers making white dust.

We also looked at the most important checks you can carry out if you notice that your Pure Enrichment humidifier is not working.

Here, we shall look at another common problem of your humidifier turning off after every so long.

So, why does my humidifier keep turning off? It could have run out of water, or it could be broken down. Also, when the humidifier is not set up properly, it might not sense the tank and therefore it might refuse to turn on.

If it is too old, perhaps it is time to toss it into the trash can and get another one. But if it is new-ish, well, it is time to do these three checks:

1. If it is a warm mist humidifier – check the heating elements

If you have a warm mist humidifier, sometimes, a layer of minerals could coat the heating elements. The appliance will just refuse to start or it will shut down after a short time.

Once you clean the elements, it should work. Perhaps you might even need to change the elements.

If it is a cool mist humidifier, try the most common checks. First, you should check whether the tank has water. Since this appliance produces mist from the water in the tank, if there is no water, it just won’t turn on. If it does, it will not run for long.

2. Check the humidity settings

If your humidifier keeps turning off, you need to check the humidity settings that you have entered. If the humidity setting is too low and the humidistat senses that the set humidity level is good, it will just shut off. Even if you restart it, it will shut down after some time.

To ensure that this is not the problem, try setting the humidity a bit higher and then watch what happens. If it works alright, you definitely have set the humidity level too low.

Also check that the tank contains enough water, ensuring it is full.

3. Check mineral deposits on the filters

Cool mist humidifiers come with filters, and when they clog up with minerals, they become hard to fix. Thus, you have to open the appliance to access the filters. You can either clean them or replace them altogether.

It is vital to note that not all cool mist humidifiers come with filters. Therefore, do not be surprised if yours doesn’t have one.

Just follow the guidelines in the user manual to open up the appliance and check inside to see what could be wrong.

If you are not sure how to go about it, just leave it so that you don’t void the warranty.
