Dehumidifiers Normal Sounds

A dehumidifier operates basically like a refrigerator and has the same components. When it is running you will hear compressor noise, a condenser fan noise, possible water dripping into the storage bucket and normal cycling on and off sounds much like you hear with your refrigerator.

Because it has an evaporator and condenser just like any refrigeration unit, you will also feel warm air blowing from the dehumidifier.
