I just bought one. Is it normal the sound changes while in use? Mine will be fairly quiet, then make a hum that is a bit louder for a few seconds.

On mine the sound changes and is a little louder towards the end. Have had no problems with it but wish it was heavier. Every time I push the door opener it slides back a bit.

I have had this unit for almost a year in live application and have not experienced any unusual noise or hiss. I am sure if the gain structure is wrong any unit could have the potential for noise. hope that's what you wanted to hear

It is a low pitch hum. Usually mine is on low and I get used to it and don't really notice it. Higher speed is more noticeable, but still more a medium pitch, not high-pitched.

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.

I think something is not right if it is 'extremely' loud. Mine was not silent but it was like a low hum.

Mine is noisier than I would expect at times, but nothing that has caused me too much alarm. I thought I heard it click a few times, but so far nothing reproducible or any overheating.

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.

If you're 100% sure it's not the source, then yes. I don't have hum unless I am on high volume but I have had a lot of source hum from my sound card. So check that out before shipping it off.

Lately, I put it on the high setting when I am not home, and change it to low when I am home so it is quieter. I have not had it very long, so this may change.

I have an older one, and this newer one I just got. The newer is certainly louder but it is just a buzz - no clanking, which can't be normal. I agree about trying to adjust that screw. As I recall, I had it on as I adjusted it and could hear the sound change. Good luck.

I hear no such noise in mine, however, I always leave mine in standby mode. I suspect you have a noisy cooling fan.

No, It's not normal. It's probably 60 (Hz) hum. Try reversing you AC plug, that should fix the problem 90% of the time. If that doesn't work try grounding the case.

I purchased one about 5 months ago and installed it and it works great but it does have a low humming when its on. You can here it working but its not very loud.

At low volumes it is not very noticable... but if you crank it up then turn off the source of the audio (like turning off your tv) leaving the sound bar on...then the hum is bad.

No I have not heard it, mine is silent, though I have yet to use it for long periods. I don't think it's normal, but if it still does what it says on the pack it's ok. If it's not broken don't fix it!

I just started to notice that mine also makes the little humming sound. Kinda annoying

I've had mine for a couple months now, and its really quiet. If I were you, I'd return it.
