How do I hook up a 4 wire dryer cord?

To hook up a 4-wire dryer cord, first make sure the power is turned off. Remove the old cord by unscrewing the terminal block cover. Connect the new cord by matching the colors of the wires to the corresponding terminals (red to red, black to black, white to white, green to green). Tighten the screws securely and replace the terminal block cover. Finally, plug in the dryer and turn on the power to test the connection.
