    The blower makes a slight noise, almost rattling. I looked at the blower unit and it has the part number M412TB31V. Now I'm not sure if that's just the wheel, motor or both the motor and wheel. I would like to replace the motor and wheel, as I can't determine exactly where the noise is coming from. What else can I tell you, to direct me to buy the correct part or parts, to replace?

    Perhaps before replacing the thing, check the screws holding the motor in place, and the ones holding the wheel to the motor shaft.'s Avatar

    So why didn't I think of that. I will check the mounting, and make sure everything is tight. Thanks labman, I will let you know by next weekend, when I will have time to investigate.
