Carrier Inducer Motor Screaming


Hello - I have a Carrier Furnace which started making horrible screaming noises when the furnace first starts to run (but before the blowers start). The sound seems to be coming from the inducer but I cant tell if its the fan or the motor itself.

One thing that I find abnormal is that the inducer fan assembly is not held tightly to the motor at all. There is a pin which holds the fan on the 'pin' of the motor, but, the fan can actually move up and down on the pin, which is certainly causing the fan to vibrate significantly (and possibly creating the noise), and its surely also significantly reducing the effectiveness/output of the fan. Is this normal? Shouldn't the fan be held tightly to the pin of the motor so that it doesnt vibrate?

Thoughts? Any insight here would be appreciated.

You are lucky if furnace is still working. If fan still closes pressure switch, you'll get heat.

Find the right one here:
