Is this purifier wet at all, or been in any heavy areas of moisture. This purifier is very undependable with moisture. It may just have to dry out. Let me know if this solves your problem or we can explore further options.
Please keep me updated, thanks

Have you cleaned the bars lately? I believe that red light means that the bars that collect the junk from the air are at capacity and needed to be wiped down.
If you don't know how to do this, pull them out from the top after having turned the machine off. Get a rag or paper town moist, but not dripping and just wipe the black soot off all visible sides of the metal bars. Lay it aside when done over night for it to dry completely, then re-insert them into the machine. Turn on and hopefully that should take care of it!

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.
