Report "Loud Vibration We just bought a new dehumidifer. The number is actually different than listed below but the site does not recognize it. It is a Haier HD308. Ever since purchasing it, it often makes a loud vibration. So loud, it's hard to concentrate, have a conversation, or hear the TV. Sometimes I just turn it off, because of the noise. I can't hardly think this is normal. Could you give us any help? If the sides are held, the noise ceases"
