Humidifiers can malfunction and require basic troubleshooting and repairs like any comfort equipment, like when seeking an air conditioning repair in Lethbridge. Typical issues include homeowners notice they are not working by when they wake up having a dry throat, or nose bleeds. As well getting shocked when you reach out to touch a light switch.

Read the manufacturer’s instructions first, and be aware that some DIY fixes may void your warranty.

Humidifiers use a humidistat to turn on and off when humidity levels fall outside of a defined range. Check the humidity of your humidifier if you don’t believe it is boosting humidity in your room or house.

Though a humidistat can aid with more or less “automatic” operation, you’ll need to adjust it as the temperature changes to keep indoor relative humidity levels consistent.

Read on to learn how to fix your humidifier if you don’t want it to stop working.

Humidifier Isn’t Making Mist

The humidifier sometimes works great but does not produce mist. Let’s start by looking at the many humidifiers on the market. Very few humidifiers installed on furnaces produce mist. IT’s best to check your owners manual to see if yours is one that has this option. If it does, check the nozzle where the water comes out of to ensure there is no build up.

Examine the Filter

If you’re using a humidifier that has an evaporative pad in it, make sure the pad is in good operating order or needs to be replaced.


Clogging is the most typical problem with warm, steam, and ultrasonic humidifiers if you use hard water. In most cases, a humidifier will stop working if mineral deposits obstruct the internal mechanism. To maintain smooth operation, regular maintenance is required.

It’s a Leaky Tank

If you have a whole-house humidifier, the water leakage issue could be caused by:

  • Increased water pressure
  • A clog in the drainage system

The solenoid valve had accumulated debris.

It is preferable to get the water pressure checked by a professional. You may also unclog the drainage line and clean the solenoid valve without hiring a professional.


While we’ve just covered the most frequent humidifier difficulties and how to remedy them, customers may also encounter other minor issues such as indicator lights not turning off, humidifiers not turning on, or condensation around windows. The best defense against humidifier difficulties is your user handbook, but it’s also vital to think about things like humidifier size.

Maintaining your humidifier will help to keep it in good working order. This certainly entails cleaning it regularly and ensuring that all components are functioning properly. This could help keep your humidifier from breaking down completely and extend its life by months, if not years.

Remember that proper care and maintenance can improve the efficiency and longevity of your equipment.
