The obvious solution is to replace the humidifier that became defective while in storage.

Very first thing. If it won’t turn on, unplug it, and check the cord....especially if you have, or have had, a rabbit that has already chewed through every other wired devices you have ie: TV, satellite dishes, DVD players, other electrical cords.
I got my humidifier year before last and only used it a few times that year. Our humidity was fine until now, so the humidifier was still new as far as I was concerned. I checked every online help suggestion before I remembered Buster. Sure enough....exposed and partially chew wiring. I thanked God that I hadn’t been shocked.
Thank you, Daddy, for teaching this 70 year old grandma how to splice wiring and install other electrical wiring when I was a teenager. I miss you so much.
CAUTION: UNLESS YOU KNOW EXACTLY HOW TO SPLICE WIRING DON’T THINK YOU CAN FIGURE IT OUT. TAKE YOUR APPLIANCE TO A SPECIALIST TO GET A BRAND NEW WIRE PLACED ON YOUR APPLIANCE. I CANNOT EMPHASIZE THIS ENOUGH. IN FACT, TAKE IT TO AN ELECTRICIAN ANYWAY.

hi Teri. i think its telling you to call someone out to come and service it or to have a look at it.

if you just got it check for packing material stuck around the fan area if there is nothing , then take it back for a warranty exchange as it is not as described ---quiet

I doubt if there is any warranty on this now. It has been over three years ago.
