Hi folks, my 5 yr old Coleman Mach 3 is making an incredible high pitch squealing noise when turned on, it eventually will calm down and just about go away after maybe 5 - 10 minutes. Spring is coming and trying things out. It started doing this last yr a little bit but vanished quickly. Of course it's out of warranty now. Anyone had this happen to them?
 
Sounds like a dry blower motor bearing, no real fix besides replacing the motor.

Not only "Dry" but worn beyond tolerance.. I will add my voice.. If it is a carrier Air V replacements can be hard to find. I have a couple sources.. If you are in Upstate SC PM me.
 
I would access the motor, take a picture of the specs on it.  Then google the model # of that exact motor.  Amazon is amazing sometimes.
