ALPINE XL15

MY ALPINE XL15 AIR UNIT MAKES A BUZZING SOUND THE HIGHER I SET IT.

Same Problem

Apr 22, 2009

-   My machine makes a loud crackling noise. EcoQuest said they could fix it for over $200.00. That sounds high and it may be cheaper to just buy a new machine. -   heatasap

-   I also have a crackling noise that stands out from the normal buzzing sound. I purchased the purifier only 2 months ago, and the sound just started last week. I have cleaned the filter and there seems to be nothing unusual, but the sound remains. -   mjensen1111

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,

Jon
