I have a duct fan that I attached to the central air line in my bedroom and I think that a lot of dirt and debris got in the fan because its not performing as well as it did before and it is emitting a faint burning smell and the motor is very hot to the touch. I think I probably should have put an air filter in front of it but is there anything that i can do to save this motor? Will it burn away all the dust and then go back to working good or is going to get progressively worse until it stops working? And could this potentially be a fire hazard cause I leave it running while I'm not at home.
Please help me guys...I'm really, really stupid so even stating what may seem obvious to you can be of assistance to me.
