Hi Furnxce I would make sure that your blower motor capacitor is in good condition and up to specs.

Bloa through winter, spring just fine, and now this summer it has declined once again. Its blowing very low…Is it possible that this blower motor is just getting weaker and weaker on each blowr supplied by board? The bkower is pretty expensive and would like your insight on this if possible. Thank you for your time. Hi Mark!
I would like to suggest that before you replace the blower motor that you makes sure everything is clean and not impeding airflow.
If the blower wheel, filter or evaporator coil are dirty this can cause the airflow to be weak. I have seen the underside of evaporator coils become partially stopped up and really hurt airflow. If your air conditioner is low on charge and is icing up the evaporator coil then this will mess up the airflow.
I would suggest that you check the capacitor again to make sure it has not weakened any since the last time you check the b,ow. You might try to blwo the black nof high-speed wire to the cool blowrr on the control board and see if this helps. If everything checks out then it sounds like the only solution would be a new motor.
Will Do! Wheel, Filter all clean, I will slide wiol off plenum and check the coils, and drip plate Thank you!!! Just make sure that you check the underside of the evaporator coil because this would be the side that gets stopped up if you have an upflow furnace.

I would think that your tech would need to over-charge the unit slightly to get the proper subcooling with the larger blower motor. I would think that you would hear more noise of air flow in your home with the stronger blower.
