Has anyone noticed a "humming" type noise associated with this product?

Yes, with my ear down close to the pad, I will hear a faint, intermittent "humming" coming from the pad. I figured that it was just the heating coils cycling off and on. When my head is on the pillow, I don't hear anything.

I hear no humming associated with this item. I have purchase two of them ( for home & Beach Condo) and have had no problems.

We have had this product for almost a year and have noticed no humming noise.

Haven't noticed any noise at all. We only have my husbands side in use because he gets cold easy and I keep my side turned off because I am plaged with hot flashed and supply my own heat naturally. If both sides are turned on then maybe there would be a sound but I haven't checked it out. I'm a light sleeper so any sound would keep me awake all night.

We have had our heated pad for over 2 years and I haven't noticed anything like this noise.

No, we love ours. A humming noise would signal a fear of electrical problem, and I wouldn't like that.

I have not had that occur. I wish I could tell you more about what is causing that noise. It might have done so, but I had mine installed by a professional and I was not there for the testing. I have not had a power failure so it has not had to kick in either, so I haven't heard it in operation.

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

I think mine makes a little noise, but definitely not a lot--sounds like yours may have something wrong with it.

My unit does not make a loud buzzing sound but does have a slight humming sound from fan operating similar to a computer. Call tech support, they are awesome

Mine makes the same sounds, I am interested to know if more people have this issue....

No there is not a detectable pattern to the noise it is just a steady hum like having a fan in the room. That is is the closest comparison I can think of. If you have any further questions don't hesitate getting back to me.

Yes- It's probably normal not a defect. I've had similar appliances in the past and they all make a hum.

I had this humming/buzzing noise problem when I bought Samsung 21". The monitor started humming after it was on for 5 minutes. It was not loud, but annoying. I returned it to Costco. Don't know what problem that was.

Ours makes a small cyclic hum. You can hear it. It doesn't bother me, but everyone has different tolerances.

Margo - I have owned this toaster for a while and have never heard any type of humming noise. It may or may not be a problem. It could be the elements reacting like some light bulbs do when turned on and will hum. I wouldn't think though that this is normal.

After moving the purifier several times while vacuuming, mine has also developed a louder whirring noise. It is obvious at all levels. Level one used to be very quiet, an almost unnoticeable hum, but now it sounds like the motor is grinding and working overtime. As it's been less than a year, maybe less than half a year, I am planning on speaking to the manufacturer about it.

Yep--I have two, and they make buzzing noises. I recently rearranged my furniture, so it might just be that I'm sitting closer to the cat beds and noticing the noise now. At any rate, they for sure buzz now.

The only noise I hear is when you turn it on. Sometimes you will hear it interchange and sometimes you don't. If it has set off for a while it will make a loud click and hum but it goes away in a couple seconds. Other than that it does not make any sound that is noticeable.

Thank you! That was definitely part of my problem. One last question: when opening, I hear a pleasant ratcheting sound, which I don't hear when closing. Does yours not make that sound

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.
