Trying to help a friend. Unit was not emitting ozone, and fan was very sluggish. Replaced fan and cleaned lint filter. It now runs properly. Ozone plate didn't look dirty but did have a dark spot where contact touches plate. Replaced plate with new plate. Still no ozone. Took plate back out and turned unit on as directed in manuel, checking for Prove-it light. No light with fan running and ozone control set at 12 o'clock as directed. Also the ion indicator lamp does not light. I'm usually pretty good at following directions if you can tell me where to go from there. Thanks for your help.

How long have you owned machine? Plates need to be replaced periodically to be effective and to generate ozone. Depends on usage but at least every one-two years. They run about $15 a piece. I can get you some.
If you are sure that the plate is clean, in perfect condition, and inserted correctly, it would appear that the transformer is defective. This means that power is not going through the metal contact fingers into the plates.
The light probably has burned out. It is not essential to the working of the machine, so it isn't anything you need to be concerned about.
Vollara (formerly Alpine/EcoQuest) is no longer producing or servicing the XL-15. However, a newer version, called the Classic, is available. You can call Customer Service 800-989-2299 and they will tell you your options. Use #16618 if you need a referral number.
The Classic XL-15 should have 2 individual indicator lights. The 'red' light is the ionizer indicator, and the 'green' light is the ozone level indicator. Both lights should be illuminated, if the unit is operating properly. The red light should be pulsing, and the green light should be dimly lit, and brightened as the output knob is turned up - indicating a higher ozone production. If the green light is not lit, you likely won't smell the ozone. The first thing you should try, is cleaning the filter and glass ozone plate. Unplug the unit and remove the rear air filter. Clean the filter with clean water and allow to COMPLETELY air dry. Removed the glass plate by depressing the lever behind the glass plate, and gently pulling it out. Clean the glass with a half water, half ammonia (or distilled white vinegar, if ammonia not available) and an old toothbrush to clean between the mesh. Dry plate with a hair dryer and re-place plate into unit. Replace dried air filter, making sure the little tab on the bottom is secured into the interlock. Power the unit on and you should see the indicator lights and smell the fresh ozone!
If it's an XL-15 or Classic, there are four screws through the bottom that hold the main chassis in-place. But first:
1) Unplug the unit, and remove the lint filter in back.
2) You'll need to remove the power switch (carefully pry out with a screwdriver or putty knife), disconnect the spade terminals (note which wires attach to which terminals), and remove the knobs for Fan and Ozone controls.
3) Remove the four screws. As the chassis slides out the back, you'll need to disconnect the spade terminals to the fan motor as well.
Clean thoroughly, make sure everything is re-assembled with good connections in reverse-order. Be particularly careful to leave any sensors clean and connected.

Several possiblities here. Not static sound means the plasma discharge plates aren't energized.
1) Missing, cracked or defective discharge plate (you say you cleaned the filter - did you mean the lint screen in back, or the glass or white ceramic plate inside)? No plate, no ozone (O3) production.
2) Bad connection in the high voltage leads*.
3) Bad electrical components*.
*I'm not an electrician, and recommend that only qualified personnel troubleshoot high voltage electronic, both for safety, and for preventing further damage to circuitry. Visible problems, such as corroded or broken terminals that can be swapped when it's de-energized (unplugged) is one thing; having to dig deeper into the electronics is something that I expect to rapidly end up costing more than it's worth.
Ionizers do cause a bad odor to happen. I work in the copier business and do work around machines that can cause an ozone to happen when there are ran. Copiers like ionizers can cause an ozone to happen because the air particles are being electrically charged. The smell isn't good to be breathing in as well.
The Consumer Products Safety Commission is going to be making a decision about the health effects on ionizers by the end of the year. Their decision can effect selling ionizers all together.
This industry should have been regulated years ago and after what happened to Sharper Image this year due to their arrogance it isn't doing the industry any favors. They went out of business because of Consumer Reports findings and tried to sue them for it.
If you really want the air in your house cleaned, the best way to do it is using a hepa filter.
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.
Confirm that the appropriate sections of the circuitry are powered up and drawing power; check the interlock switch action; toss it back to the maker because the Hi-V transformer or ladder circuit or sense or hold caps were (if testing proves) never quite functional.
