Hi Wendie286,

I just answered your other posting which described a low "humming" sound. A squeak is different. Then it's very likely the motor. You could try a _very_ small/light application of oil to the shaft where it goes into the bearings, but that's probably a short-term fix.

If the unit is over 10 years old, the motor will probably need to be replaced at some point. Below is the relevant portion of my response in your other posting.

========================================================

[fan motors]... are the only moving parts and do eventually wear-out. If it's still turning, it shouldn't be a problem - - if it starts turning slower and slower, it's time to plan a replacement motor. I have a couple, but I think FixYa's terms forbid me selling it to you directly. Recommended solutions in this case:
1) If you still know an active dealer, you might see if they have any, or if they know of a source (Ecoquest no longer supports them with spare parts).
2) You could probably find them on the web, though the last time I did this (in December), I couldn't seem to find them; I didn't have a lot of time to spend then.
3) Find another XL15 (maybe on eBay) and cannibalize a fan from the older machine (note: different versions of the XL15 had different motor mounting configurations, so me sure you know what you're getting - maybe ask for a digital picture of the prospective purchase showing how it's mounted).

If you write back with more details, I may be able to offer more precise guidance. If you want, I could try web-searching again.

If I can be of further assistance, or if you have questions, let me know before rating me.

If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

Thanks for using Fixya.com,

I own the Fresh Air Purifier that is pictured on the home page of their website and now it will not turn on. It is plugged in and the electrical wall unit operates correctly. The manual indicates it is...


If you own the same unit, then the fuse is in a fuse-block on the back. Radio Shack has them and can open it for you. Call Volarra, since you say it's new. Their tech support is free, and they can tell you where you can send it to get it fixed.

How do I know when it is time to service my Living Air 880?


This is one of the first models manufactured by Alpine, and is at least 15 years old. It's pretty basic, however, and if it's maintained monthly or bi-monthly, it probably will just keep on going and going...like another little advertising icon says!
The two most important parts are the white plates with the screens attached, and the fan. If the machine is making strange squeeking or grinding noises, the fan needs oiling. Even if no noise is audible, the fan still needs oiling occasionally, like any fan in any appliance.
To:oil:
1) Unplug the machine.
Remove the front grid, gently but firmly pull off the fan blades, and

The motor makes a squeeking sound, like the bearings are gone. Can I replace them or is it easy to replace the motor?


The motor has bushings that need to be oiled once every month or two. If you e-mail to miller@healthyti.com they have supplementary cleaning instructions available to email back to you. Those instructions include oiling instructions.

My Flair Ari purifier makes much more noise


Sounds like Motor or bearing is failing.
You could order parts but you will find it less expensive to replace unit. Than trying to repair.

Please rate. Hope this helped. If i can help you further let me know. Good luck!

Only one plate inside, it's glass edges are broken or deteriorate


I haven't seen an older Flair that I know of. There will be as many slots for plates as are required. The filter is definitely washable. Use an enzyme cleaner and rinse with hot water. The fan motor should be oiled every month or two. It should cost less than $100 to get it running in top shape.

New noise


Hi wendie286,

An electrical hum (for the plasma discharge plates) is normal. If you wind-up the "Purifier" control knob to "max", it will increase, and you'll probably be able to see a faint purple glow coming from th plates. This is normal, and is how the O3/activated oxygen is being produced.

A mechanical hum sounds more like the fan motor. These are the only moving parts and do eventually wear-out. If it's still turning, it shouldn't be a problem - - if it starts turning slower and slower, it's time to plan a replacement motor. I have a couple, but I think FixYa's terms forbid me selling it to you directly. Recommended solutions in this case:

Hi jackkikay,

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.

Thanks in-advance for using Fixya.com,
