I don't hear any crackling sound when the Ionizer is on. Is this normal? Or should I ask for a replacement?

This is normal. You should not hear any sound at all when just the ionizer is on, only when you turn the actual fan on.

Have not experienced your issues. No, DO NOT attempt a repair yourself. Please seek a qualified local appliance repair shop. It is normal for metal to "Make Sounds" when heated or cooled. If these "sounds" are new, different, unsafe, or not up to your standards, also consider replacement due to cost of estimated repairs.

What exactly made the sound? Can you inspect every inch of the strip to check for any visual damage? I have ran mine for several hours with no issues.

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.

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?

Mine did that too from day one. The box it came in was damaged and I assume that is what caused the weird noises. It wasn't worth the time and money to ship it back so I just used it until it started giving me uneven heat. Then I junked it.

This sounds like a defect. My unit is very stable and in normal use has been extremely quiet. Maybe yous has been damaged during shipment?

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.

Just got one on Tuesday 2/9/10. Same buzzing problem, but found out it was getting some type of interference from our space heater. Look for something that may be causing the same thing in your home. We turned off the space heater and now we're colder, but NO BUZZING. Hope this helps!

As far as I'm aware, it is impossible to turn off the ionizer. After the first couple of days, I didn't notice any kind of smell, though.

Mine is definitely silent. It only buzzes/clicks when there is a power fluctuation, which is very rare. I'd suggest to check your line voltage at the outlet before condemning the unit. If that's ok, then yes, your unit may be faulty.

I don't really know. Mine makes no such noise. Could it be some solder from the welding of the tank? If there is something loose in the tank could it eventually make it's way through the air hose and cause damage? I don't know. Sounds to me like you should contact the company or return it for another unit.

Sounds like it's a dud. I have a lot of these and, fortunately, have never had a problem. I'd contact the seller and ask them to send a replacement. Good luck.

Ella, this is very odd. Mine does not make any noise and the temperature display does not flash so something is wrong. You might have received a faulty unit. You might want to call Amazon. I hope this helps you. I am sure this is irritating for you. Sorry, Cindy

Hi Patricia...I had the same thing happen to mine but the high pitched noise eventually occurred on all of the speeds. It was not constant...it would come and go but it was very annoying. Couldn't figure out a way to get into the unit to see what was going on. Seemed to me to be some sort of lubrication issue. In any event we really liked the air purifier so we just purchased a new one. It works great and it's one of the least expensive on the market.

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!

Mine has a very faint ticking (electric discharge) noise when in ionization mode. But it is hardly audible from 2 feet away. Manual says it is normal. As the noise does not increase or decrease and disappears once you push ion button, i too believe it is normal.
