Installing a 4-prong electric dryer cord when replacing a 3-prong electric dryer cord is easy when you follow these directions. Place the cord through the electrical connection hole and connect the green wire to the machine case using the green screw that you removed earlier.
Next, connect the white wire, along with the white wire from the machine, to the center post suing one of the three screws you removed. This is the neutral connection.
Next connect the black wire, one of the "hot" connections, to the left side post using another of the screws. This is one-half of the 240-volt connection.
Finally, connect the red wire, another of the "hot" connections, to the right side post using the last of the screws. This is the other half of the 240-volt connection. Snuggly tighten the screws so that the wire connections are held into place, but don't overdo it.
