I replace my blower motor I have a carrier system the more blower motor burned out smoke everywhere overnight I replace the blower motor and the cap capacitor the original blower motor label was all damaged and no one could tell me what size motor to buy eventually purchased a 1/2 horsepower motor one of the clerks told me he thought my original motor was a 3/4 I install the blower motor and since it is not pushing air through all of the vents throughout the house could the blower motor size be the problem

 

The blower horsepower is usually listed on the motor and the furnace nomenclature.

Low airflow after motor replacement is often caused by reversed motor rotation. It is easiest to see this when you run the motor then turn off power and watch the squirrel cage slow to a stop.

 

It would certainly be nice if you proof read your post and added punctuation so that it could be clearly understood by all. .
