Homedics Humidifier Buttons Not Working – Easy Solutions 

Below are 10 easy solutions you should try at home to fix your Homedics Humidifier buttons.

We outlined them from easiest to most challenging, offering a step-by-step approach. 

#1: Unplug Your Humidifier and Discharge it Completely

Unplugging the Homedics humidifier and discharging it helps reset its internal components and clear possible electrical issues.

It’s the first and easiest solution to fix the malfunctioning buttons. Do this before moving on to the other ones. 

1. Turn off the humidifier and unplug it from the power source. 
2. Remove the water tank from the base and empty it. 
3. Press and hold any button on the control panel for 10 seconds.
4. Wait for 15 minutes before plugging the humidifier back in.
5. Refill the tank with fresh water.
6. Turn on the humidifier and test the buttons to see if they work. 

Note: Safely unplug and maintain your Homedics humidifier to ensure its longevity and efficiency.

#2: Tighten Loose Cords and Cables

Loose or disconnected cords and cables cause a poor connection and affect the button functions.

Regularly inspect them to ensure they are securely connected and tighten them if necessary.

To do this, follow these steps:

1. Turn off and unplug your humidifier. 
2. Check the power cord and cables for signs of damage. 
3. Replace them immediately if you see frays, cracks, and burns. 
4. Plug the power cord firmly into the humidifier and outlet. 
5. Ensure there are no loose or tangled wires. 
6. Turn on your humidifier and test the buttons. 

Tip: If necessary, use the appropriate tools to secure the connectors or fasteners, but be careful not to overtighten.

Note: Inspect the cords and cables periodically to catch and address loosening issues before they escalate.

#3: Plug Your Humidifier to a Different Outlet

Sometimes, the problem is not with the Homedics humidifier but the outlet you use. If the outlet is faulty or overloaded, it will cause a low or inconsistent voltage that affects the button functions.

To fix this, plug your device into a different outlet and see if it solves the issue.  

To rule this out:

1. Turn off and unplug your humidifier. 
2. Plug your device into another working outlet in a different room or circuit. 
3. Turn on your humidifier. 
4. Test the buttons to see if they work. 

#4: Check the Power Cord for Damage

A damaged power cord causes a short circuit or a fire hazard and affects the button functions. It usually happens due to wear and tear, accidental cuts, or exposure to water or heat.

To address this, inspect the power cord periodically and replace it immediately if you see signs of damage. 

1. Turn off and unplug your humidifier. 
2. Inspect the power cord for signs of damage.
3. If you find frays, cracks, or burns, replace the cord immediately. 
4. Plug your humidifier back in and turn it on. 
5. Test the buttons to see if they work. 

Note: If you need to replace the cord, ensure you get one approved by Homedics for your specific model to maintain safety and performance. 

#5: Inspect Your Electrical Panel for a Tripped Breaker

A tripped breaker is another possible reason your Homedics humidifier buttons aren’t working.

If there’s a surge or overload, the breaker in your electrical panel trips, cutting off the electricity and deactivating the controls on your humidifier. 

To check if the breaker has tripped, follow these steps:

1. Turn off and unplug your humidifier. 
2. Locate your electrical panel.
3. Look for the breaker that controls the power supply to your humidifier.
4. Ensure it has a label with a name or number on it.
5. Check if the break is in the OFF position or between ON and OFF.
6. If it is, flip it back to the ON position. 
7. Plug your humidifier back in and turn it on. 
8. Test the buttons to see if they work. 

Important: Before opening the electrical panel, switch off the main power supply to avoid electrical hazards. If you have protective gear, use them to ensure safety.

#6: Clean or Replace the Float Switch of Your Humidifier

The float switch senses the water level in the tank. If it is dirty, stuck, or broken, it will send inaccurate signals to the buttons and cause them to malfunction.

To fix this, clean or replace the float switch of your Homedics humidifier.

1. Turn off and unplug your humidifier. 
2. Remove the water tank from the base and empty it. 
3. Locate the float switch, a plastic/metal moving up and down with the water level. 
4. Clean it with a soft cloth dampened with vinegar or rubbing alcohol. 
5. If it’s stuck or broken, remove and replace it with a new one.
6. Reinstall the new float switch. 
7. Refill the tank with fresh water.
8. Plug your humidifier back in and turn it on. 
9. Test the buttons to see if they work. 

Note: Order the replacement part from Homedics or a certified dealer. Go to the Homedics website or contact their customer service for assistance. 

#7: Look for Signs of Visible Damage on the Control Panel

The control panel of the Homedics humidifier houses the buttons and display. Any damage caused by water, heat, or impact will lead to issues with the button functions.

If you see signs of visible wear on the control panel, replace it with a new one. 

Here are the steps to check for damage on the control panel:

1. Turn off and unplug your humidifier. 
2. Ensure you have good lighting.
3. Inspect the control panel for signs of wear.
4. Replace the control panel if you see burns, cracks, dents, or stains.
5. Plug your humidifier back in and turn it on. 
6. Test the buttons to see if they work. 

If you discover significant damage on the control panel, turn off your humidifier and contact Homedics’ customer support for further assessment and repairs.  

#8: Wipe the Buttons on Your Humidifier

Sometimes, the cause of the problem is dirty and sticky buttons. Dust, spills, or even your fingerprints build up over time.

A dirty button will fail to respond to your press or get stuck in one position. To address the issue, simply wipe them.  

To clean the buttons on your humidifier, follow these steps:

1. Turn off and unplug your humidifier. 
2. Wipe the controls with a soft cloth dampened with water or rubbing alcohol. 
3. Dry the buttons using a clean cloth or paper towel. 
4. Plug your humidifier back in and turn it on. 
5. Test the buttons to see if they work. 

Note: Do not use harsh chemicals or abrasive materials to clean the buttons on your humidifier to prevent damaging them.  

#9: Remove Mineral Buildup Around the Tank and Heating Element

Another possible culprit is mineral buildup around the tank and heating element.

If the water in your humidifier has high levels of calcium and magnesium, the mist output will be blocked, reducing efficiency and creating interference with the button signals. 

To fix this, remove the mineral buildup by following these steps:

Important: Ensure your humidifier is turned off and unplugged before starting to prevent electric shocks. 

1. Fill the tank with a solution of one part vinegar and two parts water. 
2. Let it sit for 15 minutes, then pour out the vinegar solution.
3. Rinse the tank with clean water. 
4. Use a soft brush or toothbrush to scrub away mineral deposits. 
5. Rinse again with clean water and dry with a cloth or paper towel.

#10: Replace the Fuse on Your Humidifier

If you still have Homedics humidifier buttons not working blinking, replace the fuse on your device.

The fuse safeguards your humidifier from electrical damage by breaking the circuit during an overcurrent. If blown, it will prevent the buttons from functioning properly. 

To replace it, follow these steps:

1. Turn off and unplug your humidifier.
2. Locate the fuse holder on the back of your humidifier. 
3. Remove it and take out the old fuse.
4. Look at the wire inside to see if it is blown.
5. Replace the fuse if it’s broken or melted.
6. Insert a new fuse of the same type and rating into the fuse holder. 
7. Screw back the fuse holder into place. 
8. Plug your humidifier back in and turn it on. 

If the issue persists, refer to the user manual for specific instructions or contact Homedics customer support for guidance.
