Humidifiers play an essential role in maintaining an ideal home humidity level. If your humidifier breaks, you should repair it immediately to restore comfort in your living space.

Unfortunately, as with any appliance, they can sometimes become damaged and require repairs; luckily, these relatively straightforward units can often be fixed without needing professional repair service or purchasing an entirely new device. If your humidifier needs a quick fix to keep your home comfy, check out this company for expert advice and solutions on how to care for your home air systems.


Humidifiers are invaluable devices that help mitigate the adverse effects of dry winter air, such as skin dryness, scratchy throat and static electricity issues. First, check that the power cord and humidifier receptacle work. A working light or voltage tester may help.

Check the power before concluding something else is wrong. It may have been unplugged or disconnected somehow. If it’s plugged in, ensure the outlet is working properly. It may be the outlet or a tripped breaker.

If none of these help it could be an internal power issue.

Water levels and leaks

Humidifiers work by dispensing water into the air through evaporation. Without enough water, humidifiers cannot function, and a low water level could force your humidifier to shut off automatically or make an unsettling trickling noise. Any signs of pooled liquid on the floor could indicate a leak somewhere in the system.

A humidifier usually displays two views of humidity and water levels. The first shows temperature and current water level, while the second displays hours remaining and evaporation rate. However, if water levels become too low, red lights will illuminate both views, with an audible warning sound produced when this occurs.

Whenever this occurs, the float and valve assembly may be malfunctioning. A detached or worn-out float could make an insufficient impact when low-on water runs into a tank – thus failing to trigger its water valve when required. If this occurs, your tank’s capacity won’t be met as needed by actuating automatically, preventing its water tank from receiving essential replenishment.


Solenoid valves on humidifiers serve as electromagnetic actuators, controlling water from its reservoir to an evaporator system and dispensing droplets into the atmosphere if functioning properly. If they stop working, dry conditions could result.

Over time, mineral deposits may build up on a valve seat, leading to premature failure. Cleaning it regularly with a vinegar solution can help avoid this.

To clean a solenoid, close its saddle valve (the small valve where the water supply tube connects with the valve body), unplug the humidifier and disconnect the solenoid at input and output connections.

After disassembling and inspecting for any damages, carefully clean the in-line filter and blue orifice before reassembling and testing the solenoid. If it continues to fail, some parts may require replacement.

Clogged drainage tubes

No matter which humidifier type you own, troubleshooting and repairing problems may require adjusting water levels, cleaning out or replacing water tanks, repairing drainage tubes and fixing seal leakage issues. Always ensure your humidifier is unplugged before repairs to ensure safety and avoid accidental electric shock. Clogged drainage tubes are one of the primary causes of leaky humidifiers. Drainage tubes serve the function of draining excess water from a humidifier.

They should be checked regularly for potential clogs by disconnecting and clearing away mineral deposits or debris collected. Once cleaned, reconnect them to the humidifier’s base for continued operation.
