Why is my blower squealing?
When your furnace makes a squealing or squeaking noise, it is generally a sign that the bearings of the blower motor or the inducer motor are wearing out. This is when the blower motor wheel and blower housing scrape against each other. Specifically it is the friction between these two pieces that generates noise.
Do new fan belts squeal?
A new belt is recommended once the accessory drive has been realigned. “Squeal” is a high pitched noise, typically lasting several seconds in duration. This type of noise will typically increase in volume as the engine speed increases, and is caused by relative slip between the belt and pulleys.
Why is my furnace blower motor not working?

Why does my gas blower make a low noise?
This is usually caused by the wrong adjustment of the pilot light of your blower. Readjusting it to an appropriate level should solve this issue.

Why does my furnace blower have a hum?
Then restart the blower motor and listen. If the hum persists, then so do you. When your furnace blower has warmed your house to the set temperature, it begins to run on a slower speed. This is a normal energy saving mechanism that the motor is supposed to employ.
