How to Fix Levoit Humidifier Won’t Turn On?

Tip: Regularly service your Levoit humidifier to ensure it is safe for your home and environment.

1. Check Power Connection

Before attempting any other steps, it’s imperative you ensure that your Levoit is receiving sufficient power.

In case your device has a damaged power cord or the adapter you use is incorrect, your Levoit might not power on at all.

Here are some basic steps to verify your Levoit power supply is in working order:

1. Unplug the Levoit humidifier from the electrical outlet.
2. Inspect your humidifier’s power cord for signs of visible damage, such as creased wires or bent pins.
3. Ensure that the power adapter of your Levoit device is firmly plugged into the humidifier’s base.
4. If you notice that the power cord is damaged, order a replacement cord from the manufacturer or authorized dealer. 
5. Lastly, try plugging the humidifier into a different power socket.

Sometimes, if your device has a power-related issue, it might not start, no matter which steps you take.

If you notice smoke from your humidifier’s power cable or a metallic smell, disconnect it immediately and take it to a licensed repair shop.

Note: Some humidifiers come with a safety feature that prevents them from working if placed on uneven terrain. 

2. Reset the Humidifier 

Humidifiers like Levoit rely on built-in circuit boards that control their functions and settings.

With regular use, your humidifier can accumulate static electricity, which can cause your device to power down.

The fix is to discharge the static build-up by resetting your device.

Here is how to power cycle your Levoit humidifier:

1. Turn off the Levoit humidifier if it’s currently on.
2. Unplug the humidifier from the electrical outlet.
3. Wait for 10-15 minutes to allow the humidifier to discharge any residual static electricity. 
4. Plug the humidifier back into the electrical outlet.
5. Press the power button or flip the power switch of the humidifier and check if it turns on.

Note: Ensure your surge protector is not overloaded by other devices working simultaneously.

3. Check Water Levels

Many humidifiers, including Levoit, have a built-in safety feature that prevents usage unless the water level is correct.

This is because overflowing water, or no water at all, can cause hardware damage to the humidifiers.

The fix is to ensure your device is set up to run at the recommended water levels.

Here is how to check your Levoit humidifier water levels:

1. Turn off and unplug your humidifier.
2. Open the water reservoir carefully and visually check the water level.
3. If empty, fill the water reservoir to the recommended level in the user manual.
4. Close and secure the water reservoir properly.
5. If you notice a glowing red light from your power button, it’s because the water tank is not filled or firmly placed.
6. Ensure your water tank is fully snapped into your Levoit humidifier.
7. Plug the humidifier back into the electrical outlet and turn it on.

After these steps, check your Levoit humidifier for any water leaks, especially around the base. Such water ingress can cause electrical components to short circuit. 

Note: If you suspect such hardware damage, returning the humidifier for repair is best.

4. Clean the Humidifier Filter and Base

If your Levoit humidifier has a clogged filter, it can prevent proper water intake, which might cause your device to not turn on.

To prevent this from happening, it’s essential that you clean your filter and its base.

If there is a buildup due to regular use, it must be removed to ensure proper water flow.

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

1. Power down your Levoit humidifier
2. To access the filter for cleaning, you might need to detach the top half by rotating or sliding it off.
3. Next,  remove the water tank and drain all of its water. 
4. Clean the water tank, base, and other removable parts thoroughly using mild soap and warm water.
5. Check and clean the humidifier’s filter according to the user manual. 
6. If you notice that the filter is too dirty, you might need to replace it with a brand-new one. Only use official Levoit water filters and not third-party ones.
7. Reassemble the humidifier and ensure all components are correctly fitted and secured before turning it back on.

If you notice a plaque buildup on your water tank, it must be removed.

The best way to remove mineralization is by diluting vinegar with water and using it to clean the mineral plaque. 

Note: Clean and disinfect any parts around the water filter for health safety.

5. Inspect for Hardware damage

If your humidifier is not turning on, there is a chance that it’s due to one of its hardware components malfunctioning.

With time, most moving parts can become worn down and prevent your humidifier from powering on.

Here are some general tips to check for hardware damage: 

• Turn off your Levoit humidifier and disconnect it from running power.
• Depending on your Levoit humidifier model, you must either slide off or remove the side and top panels to access its internal components.
• If screws are holding the side panels, remove them and store them safely.
• Once the panels are off, check for any loose parts and reattach them.
• Check for any wires that are not making proper contact.
• See if there are any visible signs of wear on the internal fan or oscillating disk that creates the mist.

If you see damaged components and deem they are beyond your ability to repair, it’s best to check with Levoit support for a possible fix or device replacement. 

If a capacitor has blown, your device might still be salvageable by simply replacing the capacitor.

Note: If you notice a discolored fuse or capacitor, check if it's blown or damaged. 

6. Check for Blockages

If your Levoit humidifier won’t turn on after cleaning, the next step is to check for any blockages.

Many modern humidifiers have built-in safety features that prevent them from powering on if the device detects a blocked intake.

Here are some general steps to ensure your Levoit humidifier is free of blockages:

• Check the humidifier’s air intake and output vents for obstructions.
• If you find dust or debris blocking the airflow, power off your unit and gently clean any intakes with a soft brush.
• Clean all of your Levoit humidifier vents thoroughly.
• Remove any physical barriers or obstructions that can prevent proper air circulation.

Note: If your device got shipped in a dead-on-arrival state, document the issue and contact your shipping agency for a refund.

Quick Recap

Thus to fix the Levoit humidifier that won’t turn on, start by checking its power connections and cables for damage.

Ensure that the power cord is firmly secured to the humidifier and check its water levels.
