Re: Unit 8 mos. old and now makes loud, awful noise
Mine is about the same age and has started doing the same thing. I knew it was a vibration from within, so cleaned all of the connections which did not help at all. The only thing that has helped is jamming cardboard down between the side walls of the unit and the HEPA filter. We have cleaned the HEPA filter several times thinking that was the issue. The vibration has not completely gone away, but is considerably better. The next time I clean it and redo the cardboard, I will put a piece on the top and bottom as well. Right now it only has about one inch by 6 inch strips on each side top and bottom, so 4 strips total. The noise is definitely vibration from the hepa filter and not the motor.

let it dry completely, disassemble as you would for cleaning, and remove filter unit. Inspect to make sure no paper or other debris like a seal has been dislodged. If you can see fan blade, see if it will turn with filter removed. If it moves easily, reassemble carefully and make sure the contacts are oriented correctly and any charcoal filter is on place as well. Try unit.
If noise persists, the unit has to be opened up to inspect bearings of fan/motor and to locate and remove any debris. At that time a drop of light sewing machine oil or pellet gun oil to lubricate the bearings is a good idea.
Funny you should post this when you did as I just finished reassembling my S1730.
Mine was making very loud noise, arcing violently, smoking slightly and would give a good shock when you touched the plastic covers(yes dirty plastic will conduct electric current).
1. Unplug the unit
2. Take the plastic covers off, front has four screws and back has snap at bottom, both slide up when loose.
3. Wash the plastic covers
4. take the light out and clean it with windex
5. Vacuum the inside, be careful of the two corona wires
6. Find the bead on each corona wire and while turning them slight so the edges scrapes the wire, move them back and forth to scrap the white power off the wires
7. scrape the cone shape plastic that the corona wires runs into, this build up is the primary culprit of the arcing which is the noise you hear. be careful of the corona wires again. I used an exacto knife and gently scraped it, sandpaper has been suggested elsewhere, once done scrapping, wipe down to clean any residue. The top cones are only part accessible, after cleaning mine the noise still persisted but acceptably lower than before. I think if you completely take apart the unit you can clean this cones better.
8. Reassembly is the same is opposite of disassembling.
it sounds like an electronic air cleaner, it has a wire feild that kills particles, if somethin gets stuck between those wires it will click. unplug it and see if you can see something, a fuzzball, or lint, something. its trying
A faint buzzing sound is normal - - that's the high-voltage plasma discharge simulating lightning in a thunderstorm. If the room is dark you should be able to see a faint bluish-purple glow of the metal grid on the plate(s) inside. This should somewhat louder as you increase the setting.
It should not really be so loud that is stands out in the background of normal noises (refrigerator running for example). If the buzz is loud - - like something is shorting-out internally (loud crackling sound), that would signal a different problem - - I'd need more details about what you're observing. Approximate purchase day, specific model, number of plates, general condition of the interior would all be helpful if you deem the buzz to be too loud for normal operation.
If I can be of further assistance, let me know. If this helps or solves the issue, please rate it accordingly.
hello my name is david lets see if i can help first of all the cheapest way to go would be to buy some rubber pads to place under the unit if that doesnt help they sell air conditioners with a blanket around the compressor to reduce the noise they are a little more expensive but worth it thanks for letting me help you
Can you control this odor by adjusting the ozone (O3) control? High levels of O3 smell obnoxious or irritating to some people; you want a fairly low concentration (~40 ppb - that's parts-per-Billion, not much).
It sounds like you've done everything else right. Have you consulted with the dealer you bought from? How about EcoQuest? If it's not the O3 level being too high, then perhaps there's something goofy with the unit. If it's under warranty, pursue that option. You should have contact infor with the unit; respond if you need it and I can post it.
I had the same problem and found that the mylar on the tabs at the bottom of the plate assembly was damaged (torn). I was able to repair the part myself using mylar tape. This solved the sizzle problem. I
