I have a Bryant 340MAV that the blower motor when bad in. I had a technician come out and replace the motor. The new motor does not seem to blow as hard. The first tech I talked to on the phone said that the OEM motor is a 3 speed motor. I am not sure but I think the replacement motor is a single speed motor. The motor the 2 tech put in is $60 less then the one the 1st tech quoted. The replacement motor was an Emerson 050446-0104. Is this the correct replacement part? Can anyone help me with this?
