How to Fix Vicks Cool Mist Humidifier Not Working?
Tip: Whenever possible, only use demineralized or distilled water within your Vicks device.
Solution #1: Check the Power Supply
Before you attempt any other steps in our troubleshooting guide, you must first check if your Vicks Power cable is faulty.
Furthermore, a faulty power outlet can give inconsistent electricity, resulting in your Vicks humidifier malfunctioning.
Here is how to check your Vicks cool mist humidifier for power issues:
- Unplug the Vicks Cool Mist humidifier from the electrical outlet.
- Inspect the power cord for any damage or signs of wear.
- Plug the humidifier into a different outlet to rule out a faulty outlet.
- Ensure that the outlet is working by testing it with another device.
- Press the power button to see if the humidifier turns on.
- Check if any indicator lights come on to confirm power is reaching the humidifier.
- If the unit still does not work, proceed to the next solution.
Note: Vicks devices bought within the US are only rated to run with 120V power.
Solution #2: Clean the Nebulizer or Mist Outlet
A standard yet neglected cause of your Vicks cool mist humidifier not working is a clogged nebulizer or mist outlet.
These vents are responsible for dispersing the fine mist, and if congested, your device might not work.
- Turn off and unplug the Vicks humidifier.
- Remove the water tank and set it aside.
- Locate the nebulizer or mist outlet and gently wipe it with a soft cloth.
- Use a Q-tip dipped in distilled white vinegar to remove any mineral deposits.
- Rinse thoroughly with clean water.
- Dry all components before reassembling.
- Plug the Vicks unit in, then check if it’s operating properly now.
After you have ensured your mist venting ports are cleaned, look for signs of fine white dust being dispersed.
If you see this instance occur, you have to replace the filter and descale the water reservoir.
Note: Your cool mist humidifier is designed to be serviced weekly to prevent bacterial growth.
Solution #3: Change or Clean the Filter
Some Vicks cool mist humidifiers are equipped with a removable filter that is situated inside the water reservoir.
The purpose of this filter, often also called a wicking filter, is to remove heavy particles from the water before it runs through the humidifier.
Here are the general steps to change the filter of your Vicks humidifier:
- Note if your model uses a filter-free design, skip this solution.
- Turn off and unplug the cool mist humidifier.
- Open the filter compartment and remove the old filter.
- If the filter is reusable, clean it according to the instruction manual.
- Insert the new filter by ensuring it fits snugly into the Vicks Cool Mist Humidifier base.
- Close the filter compartment securely.
After these steps, plug the humidifier back in, turn it on, and then check for proper mist output.
Note: Always put your cool mist humidifier on a solid, level base to avoid spilling.
Solution #4: Refill or Replace the Water
Many Vicks cool mist humidifiers have a built-in safety feature that prevents them from working if they detect low water levels or empty reservoirs.
This is because running without water can cause hardware malfunctions. To prevent this, you must ensure optimal water level.
Here is how to correctly fill your Vicks cool mist humidifier:
- Power down and unplug the Vicks Cool Mist Humidifier.
- Empty any old or stagnant water from the tank.
- Clean the tank with a mild disinfectant and rinse it out.
- Fill the tank with fresh distilled water to prevent mineral buildup.
- Place the water tank with the cool mist humidifier base.
- Turn the device on and check for proper mist emission.
- If no mist appears, proceed with the next troubleshooting step.
Note: When your Vicks humidifier is not in use, its water tank should be fully emptied and dried.
Solution #5: Reset the Humidistat
Vicks Cool Mist humidifier not working after cleaning can be a sign that your device has run into an internal runtime software issue.
Even if your device is adequately serviced, its electronic components can still occasionally run into errors.
To prevent this, you must discharge any static buildup on your Vicks device.
Here are the steps to power cycle your Vicks Cool Mist humidifier:
- Unplug the humidifier from the power outlet and let it discharge for 15 minutes.
- Press and hold the power button of your cool mist humidifier while it’s powered off for 30 seconds.
- Check the humidity level in the room with a hygrometer.
- If the room’s humidity is above the unit’s set level, the Vicks device may not turn on.
- Adjust the humidifier’s humidistat to a lower setting than the room’s current humidity.
- Replug the Vicks Cool Mist Humidifier and turn it on.
- Wait a few minutes for your humidifier to recalibrate and see if it starts to produce mist.
Note: Cool mist humidifiers that Vicks produces are not intended to use essential oils or medicine inside the water tank.
Solution #6: Descale the Water Tank and Base
A necessary step to perform when troubleshooting a Vicks cool mist humidifier that won’t work is to descale or remove any mineralization from its internal components.
