Levoit Humidifier Keeps Turning Off? – (7 Easy Solutions)

If your Levoit humidifier keeps turning off after a while, even though you didn’t power it down, it’s likely due to a safety feature.

In rarer cases, hardware damage or issues with the power supply can also prevent it from working.

Don’t worry. We’ve got you covered – the fixes to these are relatively straightforward.

To keep your Levoit humidifier from turning off, start by checking if the fan is working and ensure proper water levels. Next, clean the sensors, restart the device, and check the power connections. 

Why Does the Levoit Humidifier Keep Turning Off?

Levoit humidifiers, especially modern ones, have built-in countermeasures that prevent the device from working if certain conditions aren’t met.

For example, if the sensors detect that the water tank is not fully seated or there is another issue, your device will power off automatically.

Here are some of the top causes for your Levoit humidifier having power issues:

• Hardware Damage
• Power Issues
• Software Glitches
• Incorrect Room Setup
• Humidistat Stopping Use
• Too High Humidity Levels

Now that you know the basics of the top causes, let’s try fixing them individually!

How to Fix Levoit Humidifier Keeps Turning Off?

Tip: Follow our steps below in their order for optimal results!

1. Check if The Fan is Working

Sometimes, if your humidifier fan is not working, your device might automatically power down to prevent hardware damage.

If this is the case, you must manually disassemble your Levoit humidifier until you can access and service its fan.

The steps below might vary based on your humidifier mode.

Here is how to check if the air intake fan is working:

1. Turn off and unplug the humidifier.
2. Access the fan compartment, usually located beneath the filter.
3. Examine your Levoit humidifier fan for obstructions or dust.
4. Clean the fan gently using a soft brush or cloth.
5. Ensure fan blades move freely; if you notice damage to the fan blades, consider ordering and installing a replacement fan.
6. Test the unit for noise and imprompt powering down after reassembly.

Note: If the fan makes a loud noise when working, put a few drops of silicone lubricant on its bushings.

2. Ensure Proper Water Level and Clean Sensors

Numerous humidifiers, Levoit included, possess a safety mechanism that only permits operation when there’s an adequate water amount.

This is to prevent potential damage from too much or too little water.

The solution to this problem lies in maintaining the advised water levels for your Levoit humidifier model.

Here’s a procedure to inspect the water levels in your Levoit humidifier:

1. Disconnect your Levoit humidifier from power sources.
2. Gently open the water compartment and visually assess the water quantity.
3. If it’s depleted, refill the reservoir to the level indicated in the instruction manual.
4. Make sure the water tank is firmly set within your Levoit humidifier.

After you have refilled your water levels, it’s essential also to clean the Levoit sensors to ensure that they don’t prevent your device from staying on. 

• For this step, simply locate the sensors on your device and wipe them with a soft cloth to ensure they are not obstructed. 

After these steps, reconnect the humidifier to its power source and see if the issue persists.

Note: Overly high room moisture can jeopardize electrical parts in your Levoit humidifier.

3. Restart the Humidifier

With regular use, your device can build up an electric charge from the constantly moving particles.

This can cause static electricity build-up in your humidifier, potentially causing power stability issues. A simple power cycle can resolve this issue.

Here’s a guide to reboot your Levoit humidifier:

1. Disconnect your Levoit humidifier from any electrical socket.
2. Detach the humidifier from the power source if your device allows the removal of its power cable.
3. Wait around 10-15 minutes so the device gets rid of any static electricity.
4. Reconnect the humidifier to the power source and switch on the humidifier to see if it works as intended now.

Note: Some humidifiers are equipped with a safeguard that stops them from functioning on uneven surfaces.

4. Examine Power Connection

It’s critical to make sure that your Levoit is getting the necessary power.

If the power cord is compromised or the adapter isn’t appropriate, your Levoit might have issues staying powered on.

Always use the factory default power cable when using your Levoit.

Follow these simple steps to ensure your Levoit’s power source is operational:

1. Disconnect the Levoit humidifier from the power source.
2. Look over the humidifier’s power cord for any noticeable damage, like frayed cables or misshapen pins.
3. Check that your Levoit’s power adapter is securely connected to the base of the humidifier.
4. If you detect damage to the power cord, consider a replacement from the manufacturer.
5. Lastly, try using a different electrical outlet to plug in the humidifier. A faulty power socket or extender might cause the power issue.

Note: Ensure that your power strip or surge protector isn't overwhelmed with multiple concurrent electrical loads.

5. Review Room Conditions

Some Levoit humidifiers have a pre-set condition to turn off once a certain humidity threshold is reached. This is because excessive moisture can cause health issues in the form of mold or bacteria.

Here are some tips on how to ensure your room’s humidity level isn’t exceeded.

1. Use an external hygrometer (if you have one) to measure the current humidity level in the room. 
2. Look at the settings on your Levoit humidifier to see your target humidity level.
3. If the room’s humidity is close to or exceeds the target level set on your humidifier, this might be the reason the unit is turning off.
4. Increase the target humidity level on the humidifier to a higher setting than the current room humidity.
5. If possible, move the humidifier to a drier part of the room where it might sense a lower ambient humidity.
6. Turn the humidifier on and monitor it for a while to see if it still turns off prematurely.

Note: If you also have a humidistat installed in your home, it might be regulating your Levoit humidifier usage. 

6. Inspect and Clean the Filter or Wick

In case your Levoit humidifier is struggling to stay powered on, it could be because the water pump can’t work due to filter congestion.

Mineral deposits from tap water use can cause your humidifier to suddenly power down to prevent hardware damage.

Here are the proper steps to clean your Levoit humidifier filter and wick:

1. Turn off and unplug the humidifier.
2. Open your Levoit device and check the filter or wick (wicks are typically hollow cylinders made from fabric).
3. If you notice that the water filter or wick is dirty, use a brush to scrub it under warm running water.
4. If you see a mineral buildup on the filter, mix vinegar with water in a ratio of 1:1 and use it to clean the filter.
5. After this step, rinse the filter with water thoroughly. If possible, use distilled water.
6. If the filter is still dirty or congested after cleaning, consider replacing it with a brand-new one.

After completing these steps, let the filter dry, then place it back into your Levoit device to check if the power stays on.

Note: Please don't mix vinegar with other household detergents; it might react with bleach content.

7. Check for Auto-Shutdown Settings

Some Levoit humidifiers have a feature or setting that will automatically power down your device if a certain humidity threshold is detected.

You need to adjust the settings to ensure this is not causing your Levoit humidifier to power off after running for a short time.

Here is how to check for auto-shutdown settings: 

1. Locate the auto-shutoff switch, typically accessed from the main top panel. 
2. Depending on your humidifier model, you must adjust a humidity slider or wheel.
3. If you are using a newer Levoit humidifier, check for the touchscreen display on top and look for an icon with the letter A and an arrow around it. 
4. The button with the letter A stands for automatic mode; ensure it is toggled off to prevent unwanted shutdowns. 
5. After applying these settings, power your humidifier and observe if the problem persists.

Note: If your humidifier has a water level sensor, clean it thoroughly to ensure it's getting the correct input.

Quick Recap

If the Levoit humidifier keeps turning off, start by checking its water levels and if its fan is properly working.

Next, power cycle your device and check for a faulty power cable or outlet. Lastly, check your room conditions and contact support if needed.
