Based on customer reports and repair data, this part commonly fixes these issues:
Over time, the blower wheel can become clogged with dust and debris or the set screw securing the blower wheel to the motor shaft can loosen. This can cause the blower to become unbalanced and vibrate or rub against the housing. You can try tightening or replacing the set screw to fix the problem. You can also try cleaning the blower wheel with compressed air or with a soft bristle brush. Use caution when trying to clean the blower wheel as the fins are sharp and can be easily damaged. If the blower wheel and housing is damaged, the assembly will need to be replaced.
