Rainbow Rainmate making a screeching noise!

I run my son's rainmate in his room everynight. Lately it has started making a screeching noise when I first turn it on. Last night it made the screeching noise and then would intermittently stop spinning and start back up. What's wrong with it? Also, I don't know how to remove the spinner to take a look at it and clean it! Help! I can't live without this thing!

Mine started making a noise. I turned the fan by hand and could feel drag due to dry bushings. Could not get it apart to service the motor, so after removing the fan, I used compressed air to blow all of the dust out of everywhere that I could. Then I figured out where the shaft would line up on the top of the case and carefully drilled aprox 1/4 hole aligned with the shaft. Cleaned out the debris, put a drop of light weight non detergent oil at each bushing on the motor, worked in by rotating the shaft by hand - along with gently pushing and pulling on the shaft while rotating. Re-assembled and seems to be working fine. In my case, the noise was caused by dry bushings. Although I now have a hole in the top, the unit is working. CAUTION - DO NOT DO THIS UNLESS YOU ARE COMFORTABLE WORKING WITH MOTORS.

It sounds like the motor may be going bad. Not a lot you can do with these machines when the motor goes out. To remove the fan and stem, you twist the stem until in unlocks and can pull it off, next just pull the fan straight down and it will pop off.

If you have had this unit a long time chances are Rainbow will not do anything for you about the unit motor dying. If that is the case we do have a similar item that is a little more budget friendly, looks a little different but works very well.

Twist of stem from bottom, if excessive calcium or mineral deposits you can soak in vinegar. Keep hole in stem clean. Do not use harsh chemicals on any rainbow products it will compromise the materials. Vinegar should work.

Is the rainbow rainmate like a essential oil diffuser?

If the instructions don't say so, I would not do it. Oils can clog air purifiers that are designed for such pruposes.

Rainbow Rainmate Air Purifier Looking for information if the aromas/oils are safe in households with birds! Also, where can one find the MSDS documents for the oils etc.

I'm not sure if this will help or not. I never thought about the aromas/oils possibly being bad for any birds in the house. I ran mine in the small room I use as an office and I have a parakeet in this same room. She didn't have any ill effects from it. So I would suppose it would be okay. That or I have a tough old bird (which she is).

I just set up my new rainmate in my son's room with the eucalyptus scent (he has a cold/cough), and I needed to know how safe is it to leave the unit running overnight, and how long does it take for the...

Hey im a dealer for Rainbow. RockyNR1 is correct but let me just add that you can fill it to over the line if you want as long as the 'misting' still happens, be careful that the bowl is not near the edge of the surface as the spinning water might make it fall off the side. How long the water lasts is also very dependent on how large the room is that its in. Lastly you should be able to leave it run for 24/7

Rainmate question

Hey im a dealer for Rainbow. RockyNR1 is correct but let me just add that you can fill it to over the line if you want as long as the 'misting' still happens, be careful not to place the machine too close to the edge of whatever it's on as it may fall off. The rainmate can be ran 24/7 (mine does :D)as a side note the only upkeep it should need (other than the water of course) is check the little hole on the bottem of the spinner. if that is ever clogged just punch it though with a toothpick.
