    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.

    and it will shutdown after it gets hot, until it finally burns out the new motor, if left on that application!

    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.
