Has anyone encountered problem with loud noise while it's running?

All transformers hum. The hum you are hearing is the expansion and contraction of the lamentation of the iron core. Since the US operates at 60 hz AC. you will hear a 60 sound frequency in Europe and some of Canada they operate at 50 hz AC and will hear a 50 sound frequency. When you are hearing the louder tone at start up. That is because you are charging the coils of the transformer. The sound would also become louder as the electrical load increases.

While there was a noise, I did not find it significant in my application as the unit did what I needed it to do without failure, much more important to me in power conversion.

We have several and no real loud noise, but there is a noise, but works great like it's supposed to!!

No, never. We are very pleased with this transformer. It runs noise free. What I can tell you though is that the one we had before this one got fried, as someone hooked an appliance up to it that was exceeding the allowed maximum wattage. That one did make a loud humming noise before it blew. If you are certain that your wattage is a match, it might be defective. The only other thing I can think of is try setting it on the floor, that is where I keep mine. Somethimes transformers can make surfaces vibrate and cause a humming sound while running.

When I turned it on, there is a loud sound and vibration, but just for a second, after that, it's completely quite.

yes, when it's running it will make a humming noise, sometime with a vibration.

No it always seems to be loud. Over a year no better. I don't run it at night anymore because of this

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.

We have actually experienced the same issue with the banging sound. It isn't consistent from use to use or even within one session. It doesn't appear to alter the performance, but it is certainly annoying. It isn't clear what the cause is so I'm hoping it isn't causing internal damage to the machine.

When I turned it on the first time, I thought there was something wrong with it because I could barely hear that it was running. Needless to say, the noise level should not be an issue. :)

no. even after dropping mine there is no such noise, and it still works perfectly. sounds like there is a problem with yours

mine makes noise too, many HDD's do make noise, especially at the higher speeds.

I find it to be quite loud - when running it sounds like I'm stomping my feet on it. I've been running routinely at gyms for 10+ years and have never had this issue. My model may have a defect though, I don't know.

Mine is noisy too, a high pitch whirring sound. I wondered if mine was broken as well but it has great suction so I think it's suppose to sound like that :)

Mine does too! It stops making the noise when it's toasting, and will start to make it again when it stops. It sounds like it's coming from the LED display. It's not very loud, but it's surprisingly incredibly annoying.

I also just bought the laptop and I am hearing this weird clicking sounds constantly! I called tech support and they said it was part of the HDD Protection Settings, so I turned it off and the noise stopped briefly but came back. I think I will have to call again because this is noisier than the 2007 laptop I had before. If it doesn't stop I will return the laptop.

Not had that problem. Ours is 2 years old and works fine (other than the fact that its very noisy, has always been).

i just installed it yesterday and i do get a slight whistling noise. afe called me back and said to open up the crank case line a little more which is the cause of it, so i'll post back if that ends up resolving it. it's a shame though that customers have to do this to make an unnecessary noise go away.

No. I'm already having problem. It started making noise when I increase speed the second week I got it. So I can't use it as I wanted on a daily base.

My brand new one is extremely noisy as well. The sounds do not come from the belt passing along the treadmill or from my feet hitting the treadmill. There are loud rattles and squeaks that come from the area of the motor. Also, the entire treadmill deck bounces up and down a little when I run on it. So far, I am pretty unhappy with this expensive purchase.

I haven't had any problem with such noises.I still feel it's a great product, even though I have problems keeping it attached to a base because of its weight, and my swinging it around to fit my needs. Perhaps you need a new bulb. I use the standard bulb mostly because it gives off heat and warms the area around it.

My experience is that the noise is not normal. I haven't had any issues with the speaker at all.
