How to Fix Your Dehumidifier

It’s time to celebrate the fact that the cold weather is gone and the warm weather is here to stay. But don’t start jumping for joy too much because with great heat comes great humidity. Using a dehumidifier is the perfect way to maintain a comfortable environment within your home. Here’s how you can fix your dehumidifier when it starts to malfunction.


Hot & Humid, But No Water in the Tank
  • Dirty Coils – When too much dust is accumulated on the coils it can cause them and the condenser to freeze. Each time you run the dehumidifier, clean the coils.
  • Loose Fan – If the unit runs for too long there’s a chance that the fan could become loose.
    In this case, grab a screwdriver and pliers in order to tighten the screw.
  • Fan Motor – If the dehumidifier is running rather slow it could be time for a new fan motor.


Fan Blade Replacement
  • Step 1: Remove the front panel in order to get to the fan motor. Remove the fan motor.
  • Step 2: Take a screwdriver, loosen the screw on the fan blade, and remove it from the dehumidifier.
  • Step 3: Install the new fan blade, but in the exact position of the old one. A newly installed fan that’s slightly off can hit its surroundings and damage the dehumidifier even more.
  • Step 4: Reassemble the unit and test it out.


Using a dehumidifier is a great way to make an uncomfortably hot and stuffy day in the spring and summer more tolerable. It will also help prevent any mold and mildew from growing in your home, thus lowering the indoor air quality.
