Question about Ecoquest Fresh Air Air Purifier

"Replace plate" messge appears. I replaced it but the message remains!

Some time ago my "Replace Plate" message came on. After trying to clean it and replace it, and that not working, I purchased a brand new plate and installed it. After resetting the machine it still tells me to replace the plate. There is no "crackling" sound and no ozone smell. It seems as if the problem is with the plate but I don't know what else to do...can anyone help me?

    I am having the same problem. I've cleaned the plate, which is relatively new, steel wooled the contacts and still get the replace plate message.

    After cleaning our unit, we got the replace plate message and tried a new plate and it did not fix the problem. The machine runs, but is no longer giving us fresh air and the message is still the same on the machine.

Regarding "Replace Card" warning, 90% of the time it's the female metal connector on the red wire going to the spring metal connection screws... The connector can have a buildup of corrosion ( green) build inside of the crimped connection. In that case, the crimped connector will need to be replaced. The black wire may also suffer from corrosion, but to a lessor extent. The replacement crimps need to be stainless steel crimps. The copper crimps corrode easily. Another thing to look out for are loose connections. The final solution would be to replace the card, or see your friendly dealer.

Call the manufacturer. Mine did the same thing, and I had to send back for repair. No trouble since then, except now my UV lamp needs to be replaced : (

How long do Ecoquest purifier plates last?

The "Replace Plate" message comes on for more than just the plate. Is the fan still running when it displays (Replace Plate"? The squeaking noise would be coming from the fan. I don't know what all it works for. It does display when the plate contacts are dirty, when a wire to the plates is loose or corroded, when the bulb is bad or loose and when the ozone generator quits. I have encountered all of those. Plates should last a couple of years, depending what's going on in the indoor environment. Before you go any farther, call (336) 499-2505 - they give away information and will help you solve your specific problem.

I took it apart nd cleaned everything. I turned it on and it has been running on maintenance since this afternoon, at least 8 hours. I don't think it finished. There were only 2 bars showing. I tried...

Owners manuals are available from Vollara (the new name for EcoQuest). Call the company at 1-800-989-2299.
Maintenance means that something needs to be done to make the machine workable. It doesn't "maintain" or clean itself up over a period of time. Evidently some part was not replaced or was inserted incorrectly.
"Add plate" means that the machine needs the 4" square white plate with the screen center inserted into the machine. It needs to be put in so the top and bottom of the plate follow the "tracks" or slots, into the machine. It may be inserted incorrectly so the machine does not detect it. That would appear to be the problem.

I was doing cleaning and maintance on my fresh air unit, I noticed the red wire was no longer connected to clip that powers ac to ozone plate. I trimmed red wire till burned part was gone got good wire...

Congratulations! You did better than many dealers!

Hopefully, the answer to your problem is far easier than replacing the clip!

On the right side of the front panel, among the manual controls, there is a tiny little "reset" button. While the machine is running, press that button.

Then, turn the machine completely off for a few minutes, and then power it up again. Hopefully, that will take care of the message.

If not, inspect the plate. Are there any defects or lint particles? Check the placement of the plate. Is it inserted in the tracks, both top and bottom? Are the metal contact fingers pressing firmly on the metal screen portion of the plate?

If this still doesn't take care of the message, there is something wrong with the wiring, plate, or contacts, or the computer is malfunctioning! Call Vollara (new name for EcoQuest) customer service 800-989-2299 and ask for repairs. Someone there may also have suggestions, before you go to the trouble of sending in the machine. Use #16618 if you need a referral number.

When that message appears the plate does not make good contact with the two contact points. You can use rubbing alcohol and a q-tip to clean the points. After 1-2 years it is also advisable to change the purifier plate. Plates are about $15 and can be purchased at

If the plate is dirty (and this can unnoticeable grime-grease) clean the plate with 1 part clear ammonia and 1 part water. An old tooth brush works great.

Message says Replace Plate

the circuit board might be the issue here. There is another possibility.

Sometimes the contacts that connect to the place do not make good contact. You can try to carefully bend the contacts after removing the plate to create a tighter fit. Be careful not to move/force the little bar where the contacts are connected to.

Cleaning the contacts with denaturalized alcohol might work too.

Hope this helps!

I can give you some possibilities. A loose connection, a broken or corroded wire and/or terminal end, dust or moisture on a circuit board, the plate needs cleaning, the contacts for the plate need cleaning, the bulb ballast needs to be replaced, the bulb may not be properly installed, the support posts for the plate need cleaning. These are all I can think of at the moment.

Make sure you have the filter on the back on the right way and not reversed. On the Ecoquest Breeze you should plainly see the obvious pull tab, at the top of the back filter panel, after putting the filter back in place.

When you clean this unit, the plate should be soaked in a 50% amonia to water solution for about 8 minutes. Take a toothbrush and scrub each side of plate and let copletely dry. Take a qtip and dip in rubbing alcohol and swab each of the metal electrodes that touch the plate....This should have that freash air smell back again.!!
