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:
1) If you still know an active dealer, you might see if they have any
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 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,

Jon

While the device is turned off and the filter is out, tip the unit itself upside down and back. Do this several times, there is a slider type cleaner inside that moves as you turn the unit. Be sure to do this every time you clean your filter and you will never hear a peep out of the thing.

Alpine XL-15 fan has stopped working


Hello night light,

How you proceed is going to depend on how comfortable you are taking it apart.

Given it's age and purchase condition, warranty isn't an issue. You will either be able to dis-assemble the purifier and try taking the motor apart and reassembling, or you can find a replacement motor (I've seen some on the web, they start at ~$50).

Another possibility is that the fan pot (the rotary switch that the knob turns to adjust the fan speed) may be out. If you have a multi-meter, see if you can get a signal through (when it's all the way open). If not, try replacing that first. Parts are available onthe web, I can't advertise per FixYa's terms of use.

Hope this helps.

Making sizzling noise


Unfortunately Sharper Image has discontinued support on the product line.  There was a recall going on with the product but since the company is chapter 11 right now, I don't think it is being honored right now.  
What happened was Consumer Reports ran a test on ionizers, Sharper Image received a bad score and filed a lawsuit.  They lost the suit and had to pay all legal bills. 
EPA has reported that using ionizers in a house or business may be harmful to your health.  You can read an article about it on their website.
 
The Consumer Products Safety Commission is going to release a final report on all ionizers by the end of the year.  Their decision may discontinue all sales of any ionizers in the United States.  This industry should have been regulated years ago just by the EPA data alone and for some reason it has been ignored.

Ionic breeze is arcing inside unit


I have a sharper image ionic breeze hybrid gp that ran fine for years unitl it recently started sparking / arcing at the base of the grid blades and always in the same spot. I cleaned it several times but the sparking always came back and the unit went into either "drying grid" or "attention required" mode. The solution I found was to stand the removable grid in 2 inches of Pine-Sol cleaner 50/50 diluted with water for 24 hours then brush again with the cleaning brush and hot water. Presto! No more sparking.
