Try putting a pair of shoes on it for an hour or so, they should warm up. You should not hear any noise as it is just a heating element that causes a natural thermal draft.

there is no noise - just let it warm up - heat will come up in a nice loe flow

Just put the boots on and leave them on for an hour, then stick your hands in the boots... They should feel warm, if not, send it back...

Mine is a gift so it hasn't been opened yet. Thanks for the warning. I'm hoping mine works like those who commented earlier.

I don't think you are supposed to know it is on, put your shoes on it for a while then go back and feel your shoes, if they are warm then it is working

I wondered the same thing because I didn't hear anything at all. Just leave it plugged in for a while and check it later( at least an hour. ) if your shoes are warm it's working ;) most people just put their shoes on at night and take off in morning to put on dry warm shoes.

It does not make any sound at all. I have two of them and you cannot hear either.

I agree with the previous response. If you know the outlet is good and its fully plugged in and you push the on button and nothing happens most likely the power supply in the unit is bad. Time to return it.....

Sounds to me like you received a dud. I would return it for a new one from Amazon.

Mine worked as soon as I plugged it in. If you do not feel cool air coming up through the opening in the table, there may be a short in the fan system. This is just my guess.

Uh oh. Mine doesn't do that. I just here a slight surge when I plug it in. Good luck

Mine works 100% fine. Never encounter anything. Your unit might be defective.

Assuming that it is charged (not even sure that would cause it) it sound like it is defective, I tried to get mine to do that and it won't. Oh, and mine works just fine, actually pretty impressed for the price.

No, my unit does NOT make such a sound. I DO think it is faulty. Please return it, ASAP, but be sure you tell them why.

I have not had that problem, love mine, sorry I was not any help, sounds like a defect or an impedance problem to me.

Sorry you are having trouble with this. We just plugged ours in and it has worked for about 6 months now. Maybe its not compatible with your computer? Maybe you could try it out on a different computer and see what happens. If it doesn't work then, I'd send it back. Sorry if this wasn't much help, I wish you the best.

I have 2 and neither of them makes a sound. When I plug them in the blue Let lights briefly then goes out. When charging the blue and green LED light alternately. When at rest there are no lights on.

Mine does not make any sound at all, how ever when I first got it and plugged it in , i checked all of the adjustable settings and they were right on. I left my two way radio plugged in for about a week on six volt, took it out one day and did not get one hour of operating time, the battery was low.When I got home I checked the voltage again, my six volt now only puts out three volts. I have to switch it all the way up to twelve volts to get seven volts. I would not buy another one of this brand. Maybe just bad luck I don't know. Dave

The red light won't stay on. I've plugged it both in the wall and on my computer and I have no indication that the charge is holding. Is this happening to anyone else or should I return it? I only got it today.

I am guessing you have a defective one. Mine works perfect; on/off and nothing more.

must be a malfunction...the one I just got makes no noise, nor the one that came with my laptop made noise...get a replacement!

Unplug it for a time and plug it back in. If that doesn't work it sounds like it is defective.
