How to Clean electric motor in air purifier

I have many small air purifiers. Some run good, smooth and quiet. Two dont run well. Motor sounds dirty and is louder compared to when unit was new. Hear "rubbing" and/or "scrapeing" sound. And when I turn unit off, the spinning fan blade does not smoothly spin slower and slower until comming to a fukk stop.. When I turn it off, the blade quuckly slows and comes to an abrupt stop. Applying differnt lubs help, but need to clean motor but scared to take motor apart. Any Help?

SOURCE: Sharper Image GP Silent Air Purifier with Ionic Breeze s1730

i have 2 units, and had this same issue happen 3 times. Tonight it happened with a forth, last time i had to talk to management to get it replaced outside of warranty. Ionic breeze has major quality issues, and I would NOT buy anything else from sharper image. They also reduced the warranty from the original model drastically. for the price these were, they should be covered lifetime to show their commitment to their product. there is also a class action lawsuit against sharper image, for their false claims for the product...i believe sharper image chose to settle.

SOURCE: Red Cleaning Light won't turn off

If the cleaning light stays red it is do to a failure of the nichrome wire sensor that detects deposit build up. This wire is locatied in the center where the grids are removed and easily broken. It runs from top to bottom twice. Look inside and if you see a loose wire that looks like a fine thread that is your problem. Not a do it yourself job.

SOURCE: Install Plate Displayed

Hi Wayne, glad to hear it's working again. Sometimes turning it off and let it sit for a while does clear some of the problems weird enough.

I'd appreciate your feedback.

SOURCE: Ecoquest Flair Air Purifier leaves black residue on walls and...

Hi there,

The black residue is what is in your air. The reason for it to cling to the walls is the Ionization process that the machine creates. The ionization is to create a clean breathing space, free from contaminants. All particles floating in the air will be negatively charged and cling to each other or to objects in the room (like walls) that are positively charged.

If you cook, there is some smoke created, or when you burn candles. These greasy particles will stick to the wall or to surfaces. Cleaning them up regularly might help. You can also try another product from EcoQuest called EcoH which is based on enzymes and cut through that grime easily. That might take the black stuff off the walls.

SOURCE: I have 2 ionic breeze air purifiers sharper image.(germical )

I have the same problem as gerardperez7. One of my germicidal light quadras won't turn the light on and doesn't appear to be cleaning the air at all. I even put a new light bulb in it and it doesn't fix the problem.

The Fan on my "Fresh

It could be getting clogged up. The lint screen has GOT to be kept clean or the machines fan will pull dust into the machine and it will cake on everything inside, including the fan(will make more sound while running) and can get into the bearings of the fan causing the problems you mention. It may also be a poor electrical connection. If you have ever OILED the motor...you'll have to clean it. It's not meant to have a lot of oil or grease on it.

Electric motor makes screeching sound and stops running.

The motor has worn bushings making the motor shaft hot and swell and eventually seize. You can let it cool off and it will more than likely run again until it heats up again. The motor will have to be replaced if you want to repair it.

We have model 11502 air purifier. Recently turned it on and it ran for a few minutes and then stopped. Motor sounded fine- no squealing, didn't slow down before it went off- just stopped like it was...

Yes there is a thermal cutoff that will shut the motor off for a period of time to protect it from getting to hot. If this is what happened after 20-30 mins. the motor should come back on and run again. If it does I would try to clean motor as best I could using a soft brush, vacumn, and blow out with air if possible. Clean fan of f as best you can to help motor run cooler.Hope this helps.Thank you

It is making a lot of noise. I believe it is the fan and I have oiled significantly with silicone spray on both sides of the fan motor and it resulted oin only a small improvement.

you will need to remove and clean but as a last try use a good deggreaser to wash off , try and use WD40, the use light oil-SAE40 to the fan spindle points and check out.
It will improve a lot but repeat the process a few times ,then switch on and repeat.

Oreck XL air purifier motor failure

My Orek was making such a bad noise that my wife was going to sell it at a garage sale, I'm glad she didn't. It takes about 20 minutes to fix. All you need is a phillips screw driver, can of compressed air (or air compressor) and a can of silicone spray.
Pull out the filters and turn the unit upside down. Using a phillips screw driver unscrew the 9 screws holding the bottom to the top. remove the bottom. Use care as to not damage the fan. The fan will stay attached to the motor , pull on it and use a good cleaner like 409, Simple Green or a similar product. Wash clean and dry. Next get out your air compressor and clean everywhere, see the silver bearing holders on the side of the motor? Get out your can of silicone spray and give a good squirt on both bearing (close to the shaft. also spin the motor with your hands. See the large thing attached to the shaft? Those are the windings. See the metal housing the winding spin close to? Spray the silicon in there, a good amount. Make sure you didn't get any silicone on the end of the motor shaft where the fan sits on. If you did get some nail polish remover or acetone and wipe clean a few times. Then reassemble.
My Orek was horribly noisy, now it's quiet. My wife says is beeter than new.....

Also make sure the safety interlock switch is properly closed when re-assembled. It's the springloaded switch inside the little notch in the chassis - the small tab on the lint screen should fit in and push that switch closed. If you do it wrong, the unit won't work. You should hear an audible click when the tab closes the switch.
