Anyone had problems with the fan?????? I can put it on full blast but after a couple of minutes if that it seems to slow a bit make a faint screeching noise nd then go off altogether???????? This happens everytime.........I leave it for a few minutes nd put it back on but the problem repeats itself..........it's fine now but I'm gonna need my blowers to clear mist nd stuff as winter comes in.........any ideas??????

Some of my fans can get a bit screechy, but in the main they're well behaved. 

 

Security sort out the obnoxious ones 

 

Sorry, not v helpful, but couldn't resist with that thread title...
