Humidifier Troubleshooting Guide


A whole-home humidifier can help homeowners living in a dry climate — especially during the winter months. Too little moisture in the air can cause dry skin, static cling, and respiratory problems. Dry air can also take a toll on your home’s furniture, houseplants, or wood floors.

If you have a whole-home humidifier and are experiencing problems, check out our troubleshooting guide to take care of common issues yourself and save money on a service call.

What to do when your whole house humidifier is not working

Repairs should always be left to professionals, but there are a few things you can do at home to troubleshoot possible humidifier problems. If your whole house humidifier is not working as well as it should be, follow these simple steps:

  • Turn off the power and water supply.
  • Loosen the nuts or remove clips on the cover, then remove.
  • Remove drum and check the foam pad for mineral build up from the water being used in your humidifier. If the pad feels hard, either clean or replace the pad.
  • Turn on the water supply again.
  • Allow the reservoir to fill and then reassemble the cover.
  • Turn power supply back on.

After you have performed this maintenance, wait about one hour, check the water supply again and adjust accordingly.
