Blower motor for Trane and American Standard equipment. We supply the genuine Trane factory part for your Trane or American Standard unit. If you are not sure of the correct part number contact us with your equipment model number and we will be happy to verify you are getting the correct part for your repair. We do not recommend using aftermarket blower motors as this usually leads to a more difficult job and can shorten the life and lower the efficiency of your equipment. When re-installing the blower wheel be sure the set screw is tightened down securely on the flat spot of the blower motor shaft. If it is tightened on the round part of the shaft the wheel can work loose and it will be very difficult to remove the blower wheel for subsequent repairs.
