My Turbo Air Purifier shuts off on its own after about 1 minute when it's on high and about 10 minutes when it's on low. The blades are spot free and I have pulled the fiber cleaning rod up and down numerous times. The Clean Me light is not on. I have reset it by holding down the power button for about 10 seconds but nothing works. Of course the one year warranty just ran out. Any ideas? jerry_bauer@hotmail.com
