Is this motor fried?

My furnace blower motor got hot and shut off (thermal overload I'm assuming). When it cooled down again and I ran it, it started squeaking. Spinning the motor shaft by hand gives a fair amount of resistance - it doesn't coast like a good motor should.

GE 1/3 hp, 1075 RPM, 3-speed direct drive - about 18 years old. Split forced air system, natural gas.

Is replacing the motor the most practical option at this point?

>>> I happen to have a 1/2 hp, 1000 RPM, 4-speed motor on hand. Is it okay to substitute this motor temporarily?

It sounds like the motor bearings are worn.
It would appear that you could use that motor temporarily.
Confirm it's turning in the correct rotation.

Thanks, Pete. I think it's more like the bearings are beginning to seize - the shaft is difficult to turn by hand. Can the bearings be replaced or it is more practical to replace the entire motor?
