Can you rewire a humidifier to make it a dehumidifier?

No.

I'm just talking about a small, probably 1 gal. home unit. It's not a central air nor furnace unit model.

It would be easier to redefine the laws of Physics.

Please purchase a dehumidifier.

One takes moisture out of the air using a condenser. The other puts humidity into the air. There is no way you can just "rewire" to get this to happen. Nice try, no cigar.

I like Don's answer!

Are you trying to remove the humidity from your home so that your ceiling fan will work? Just curious...

Ceiling fans should work no matter how humid it is.

And to the original poster, no, and NO.

Hey maybe if they flip the plug around and plug it in backwards it will work? Maybe if they set it upside down?

Who knows... I have honestly never heard anything like this before, and I have been asked some pretty wild questions.

I was making a joke, those two things won't work
