    208volt for residential? 208 Volt is usually 3 ph. I would call a Pro before you end up spending
    more money on parts, so he can trouble shoot the complete system.

    MOTOR; 1/3HP, 200/230/60/1, 825 RPM, 48 FRAME, PERMANENT SPLIT CAPACITOR, SLEEVE BEARING
    This is what should be on the unit. Call a service tech and have it done the RIGHT way. Don't be cheap.
    The fan blade that you have on there now is the original blade for an 825 motor.
