Furnace Fan Noise
I recently replaced our furnace fan on our Coleman furnace. It is louder than our previous fan. There is also a humming noise that gets gradually louder, but often stops before the blower comes on. At times I can hear the hum again when the blower is on.
Any suggestions would be appreciated. Thanks, Bryandshell

Was this an identical replacement?
The humming prior to the blower starts may be an indication of a motor having trouble getting the fan wheel to pick-up speed...maybe your new motor is undersized.
