The blower motor (which is brand new 1/2hp) will not start unless I turn it by hand.
It appears to be the capacitor, but I have no idea what the capacitor looks like or where it is located. Can anyone help please. Much thanks

Here are some pix of cap's. Follow the 2 brown wires from the motor to the capacitor. If this is an ECM motor you have a whole different problem.
