Blades will not go back into the air cleaner

To stop the crackling sound, you need to remove all of the dust particles from the wire in the back. Sometimes when the unit is extremely dirty you can see sparks emanating from the wire, this is what causes the crackling sound. The unit has a built in cleaner you can lift up and down to perform this task, located on the top, but this doesn't work extremely well.

I usually take a can of compressed air and blow as much of the dust I can off the wire and all surrounding internal areas as I can. To do this, approach the unit from the front, and turn the blade door slightly so the wire can be seen. This along with a thorough cleaning of the blades should eliminate the crackling noise. Of course, make sure the device is unplugged before performing any cleaning.

I keep the blades clean. Really clean. I'm a smoker, and you would not believe the crud that accumulates on those "blades"... <g>

First, I spray the blades with "PurplePower" cleaner/degreaser (from AutoZone), then I wipe them down with a sponge, then rinse with hot water. then dry them with compressed air (I have a compressor...).

FWIW, "Windex" works pretty good too, but... the degreaser really works well on the cigarette "residue"..

Second, there are two long wires inside that also have to be cleaned, periodically.

If your unit has the "pull-tab" cleaner, use it. One of my units has it. The other two don't.

On the ones that don't have the built-in cleaner, I stick a chopstick in through the rear vents, and CAREFULLY rub it against the sides of those wires, which "scrapes" the "white crud" off of the wires. Take your time. You will likely have to "change locations" several times in order to access the full length of both wires.

NOTE: those wires are fairly durable, but BE CAREFUL with them.

Either way, after cleaning the wires, I then "blow" the unit clean with compressed air.

Voila! No more buzzing. Until the next time the wires get "crudded up".

you have to wiggle the blade handle so that it knows the blades are back in, just push down and towards the front while pushing the on button repeatedly until you hear it click

best best is to unplug the unit, and clean the blades completely with a damp cloth, then wait a few for the blades to dry and put them back in the unit. usually cleaning these every 2 to 3 weeks and they should be kept clean to be effective at removing the contaminants in the air. theirs alot of controversy over thease untis thease day's butthey do fuction properly if kept in top condition. also note that the blades must be properly seated in the houseing to work. safty feature that if bumped or knocked down it will cause the system to mostlikly stop working till you pull the blades out and put them back inj. i observed this myself with a model and they are failry good quality but a pain to clean. good luck with it.

Not sure about the smell though. Mine has started to smell a little strange and I haven't figured out how to fix that problem.

After cleaning the unit, blue light turns on momentarily then red cleaning light comes back on. Have cleaned and dried unit including the contacts on the end (cleaned with alcohol). Sounds like a common problem, any solution?

Does anyone in your house smoke? Could be from cigarettes. I was told by the Ionic Pro Company to clean the blades with rubbing alcohol.

I used a can of compressed air to clean my fan blades and this did the job. I bought a 6-pack of 3M Dust Remover at Sams Club to save money. Hope this helps.

I found that the buzzing can be removed by blowing out the unit, cleaning the blades and taking a long cotton swab and alcohol to thoroughly clean the corona wire - carefully - don't break it. The wire should be clean enough that the slider/wiper runs smoothly up and down the wire after cleaning. If it drags or is rough to slide, you will still have noise no matter how many times you clean the blades. The wire gets a "crust" on it.
