I just received 2 fans. They both have a high pitch sound that hurts our ears- not the crackling that others have mentioned. Is this normal?

No, when the unit is on high it is loud but no high pitch noise and on whisper it is very quiet.

My units have always been almost silent. There could be something stuck among the grates of the filter itself. You might try washing and drying properly and restarting? Ear-hurting noise is NOT normal. Good luck!

I have the larger model. I have cooked White and GABA brown on this. It is not very loud. There is a low hum while it is cooking/prepping from the internal fan, which sounds like my laptop when it isn't working very hard.If yours sounds like a grinding noise I would suspect that either something is in your fan causing it to grind, or you otherwise have a faulty fan. I don't think there are other components in there which are capable of making loud noises. Unless there is some process of induction cooking for which I am unaware that might cause this.

Seems to be the case. I was equally as disappointed with the extreme noise of the motor/fan.

Don't know decible level but there is a noticeable fan noise - especially on high.

I have had the biocube 14 running in my living room for almost 2 years now and I don't think i have ever noticed the sound of the fan. It is possible yours is rattling in place or you have a faulty fan? If it is actually loud I would contact the manufacturer.

I have only had the unit one night, but the fan noise does seem a little loud. Which is unfortunate because I kept reading how quiet it is and that is one of the main reasons I bought one. Not sure if it is just my unit, or if this is just how normally loud it is for others? Also, my fan ALWAYS seems to be running, even if I am not pushing it hard at all.

I purchased an XBR4 46" the last week of December. It had a fan noise or hum right out of the box. I have it on a table, so there are no enclosure issues here. I also have it plugged into its own outlet and not a power strip with other devices. The noise is very irritating especially since I know other people that own the XBR sets and they are dead silent. I returned to Amazon. It was painless. My new set was just delivered this past week and it is every bit a noisy as my first one. I love the picture but hate the noise. I also don't think the noise is normal or acceptable. I will contact Amazon this week to see what they are willing to do. I purchased an XBR4 46" the last week of December.

Not much crackling in mine either but dont really care - it works great. If I get real close I can here something like a crackle but the fan kinda overwelms it as we always have ours on high

At low or medium, its like a babbling brook... On High, it kicks up quite a bit, but doesn't bother me. I run it on high all day, and turn it to medium for sleeping. As NFB replied, its like white noise, no tonal pitches, just a smooth fan sound.

I havent installed it yet. My existing was sounded like the bearings were going out so I got one ordered, but it quieted back down. I would make sure that the drain on the bottom is clear so your not getting condensate in the bottom of the fan. If it were a high pitch noise, I would say it is a bearing, but low pitch noises are normally imballance - which could be caused by things like a little rub on a blade, blade manufaturing defect, condensate in the bottom, pluggage on the inlet or outlet, or a slight missalignment. Hope this helps and good luck. Sorry for the late response. I thought this was just junk email from amazon. I havent installed it yet.

It is more of a loud whine. People on all sides of my cubicle could hear it, even the ones that sit diagonal. Fan only worked for 2 hours. Might want t try something different.

A good percentage of reviewers find the cooling fan noise a problem, ranging from an annoyance to reason enough to return the set. That's a "defect" -- not in the individual unit, but definitely in the design. If there were a red splotch in the corner of the screen, and the manual said it was normal, would that make it acceptable?

Hi Terry. Good point. Worth asking the seller. I don't know if all ac from them have the same issue. Plus, people may have different levels of tolerance for noise. I couldn't sleep. Maybe it is just me.

No.No.No.My fan makes an irritating noise on high speed that sounds like a howling wind. It is on now and I use # 2 selectionand its not doing that and I think the vibration comes from the "honeywell" button on the front.

I have a unit which makes a noise like a normal fan would make. It does not make loud unexpected noise. There is a compressor unit in it like the one freeze and that has its own noise Apart from that I am not sure what kind of noise you are getting. Thanks

If you use the fan, it has a high pitch/whiney noise when using the a/c adapter. on battery the fan is pretty mellow, so much its fairly useless. So buy the a/c adapter if you want the air circulated around.
