Subject:Re: HUM I got a BIG ONE !!

My comment was not meant to hurt you bro. Sorry if I wasn't clear enough. What I meant to say is that it may well be that the hum doesn't come from the Ventilator itself. Maybe it's a faulty AC adaptor or a bad cable in the Vent chain or whatever. Hum sometimes is a real mystery. I wish you the best of luck in fixing it. Fingers crossed!
