My fedder dehumidifier m7dh45b2a makes an annoying buzzing noise when it operates. What's causing this noise? What do I do to fix it? It's 4 years old.
Hi,
This noise is the vibration from the compressor...sometimes things can come loose and magnify the noise...check for loose parts and tighten as needed...
The compressor may also be going bad...
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier.
Dehumidifier is running but no water is in bucket
