I HAVE THE FRESH AIRE MODEL JUST REPLACED rci CELL CLEANED FILTER AND CLEANED THE OZONE PLATE. THE FAN KEEPS TURNING ON AND OFF?? STARTS RIGHT BACK UP ON ITS OWN AND THROWS NO EROR MESSAGES??

It doesn't sound fixable in the field. It may be a control panel issue. Contact Vollara (which bought Ecoquest) & get through to tech support. 800-989-2299.

Did you clean the plate contacts with alcohol? How old is the plate? Is the glue that holds the grid in place turning brown? If it is, it may need to be replaced. Call (336) 499-2505 and ask for free email supplemental cleaning instructions before you do anything else. The instructions may help you solve the problem.

Fresh Air purifiers are noted for two weak points. The display circuit board and the main circuit board. Call (336) 499-2505 and they will help you work through the problem. They give away information.

It will operate without a purification plate, as long as you are running in RCI mode or normal mode. If you normally run the purifier with some ozone output, then you will need a purification plate. Hope this helps you.

Unplug the machine and unscrew the phillips head screw on the back grill of the machine, that is just above the plug. There are depressions on the sides of the back grill that has a plastic tang that hold the back grill to the machine. Press the back grill inwards to allow the tangs to clear the sidee and the back grill should now be easily removed. Remove the two thumb screws on the top corners to remove the filter. Once the filter is removed, then you can remove the purification plate and remove the two screws that hold the RCI cell. The RCI cell and filter can be cleaned by vacumming out the dust and dirt.

The purification plate can be cleaned with a old toothbrush and a water and amonia solution. Scrub the metal grid with the toothbrush. Do both sides and then rinse with water, allow it to dry completely before reinstalling the plate. After every part is cleaned reassemble the purifier, and plug it in. Then press the reset reminder button on the front of the keypad to clear the "perform cleaning" message. This message will appear again after the purifier runs for 30 days to remind you to clean the purifier. Hope this helps you.

The Fresh Air has a reminder on the LCD to Perform Cleaning. This reminder will display if the purifier runs for 30 days. When this reminder is displayed perform the following steps to clean your purifier.

1. Cleaning the Case:

Wipe the unit with a soft cloth dampened with water. Do not use chemicals or solvents. Vacuum the front and rear grills to remove any lint buildup.

2. To clean the lint screen, RCI cell and purification plate:

3. To remove the back cover:

Remove the plug from the back of the unit. Unscrew the screw above the plug socket on the back cover. To remove the back cover, press the back sides of the back cover to unlatch and tilt the bottom of the back cover to remove.

4. To remove the rear lint screen:

Remove the two thumbscrews holding the top of the lint screen. Remove the lint screen by pulling back the top of the screen, then lift it up and out.

5. Removing the RCI cell:

Remove the RCI cell connector by pressing the connector locking tabs. Pull the connector straight out to unplug.
Remove the RCI cell by removing the two thumbscrews. Slide the RCI cell down and out of the unit.

6. Cleaning the RCI Cell:

Remove the RCI cell and carefully vacuum accumulated lint. Do not wash the RCI cell. Damage from water may result.

7. Rear lint screen cleaning:

You have two options

1. When visibly dirty, simply remove the rear lint screen from the unit and with a duster attachment on a vacuum, remove the heavy particulate.
2. In addition to step 1, the filter can be washed with hot water (do not use soap). Allow to dry prior to reinstalling. Replace if damaged.

8. Cleaning the Purifier Plate:

Remove the plate from the card cage by grasping the middle edge nearest to you, and slowly pull it straight out. Clean with mixture of one part water and one part ammonia. Place plate and ammonia mixture in a dish and allow it to soak for no more than 10 minutes. Remove plate and scrub with a toothbrush. Rinse thoroughly and air dry for 24 hours or use a blow dryer to dry thoroughly.

After all parts have been cleaned and are thoroughly dry, reinstall components in reverse order. Turn the purifier on, and on the key pad, press the reminder Reset button to clear the Perform Cleaning message.

The main circuit board is probably bad. It seems Ecoquest installed a number of them that have a problem. If the machine is under warranty, they will replace it if you pay shipping. Otherwise, you'll have to pay the whole bill. Either way, call first to get and RMA number.

My XL-15 had the same problem a few years ago. I had a broken wire on the fan, and the Ozone problem turned out to be a problem with the power supply. I had to send it in to have it repaired.

Whenever you clean or replace the plate, you must also clean the contacts that touch the plate, and all supports for the contacts. Clean them with 70% or higher isopropyl alcohol and Q tips. You should also clean the ionization point with a Q tip and alcohol, remove and clean the fan and oil the fan motor front and rear with a drop or two of sewing machine oil. Replace the fan so that it is flush with the end of the shaft. Make sure that the contacts are firmly against the ozone plate when you replace it. They sometimes barely make contact and then don't work well. You can bend them enough to make them fit firmly.

The fan is bad it should blow the fuse, I believe that the mother board has a problem, or the Display board may have gone bad.
