Hi, my name is Chas, I am hoping that I will be able to help you with your problem today..


A 4 wire dryer cord contains a black, red, white and green wire. The red and black wires are hot live wires and get connected to the 2 outer connectors on the dryers power terminal block, doesn't matter which is which as long as it is the outer two connectors. The green wire is a ground wire and gets connected to the frame of the dryer. The white wire is a neutral wire and must be connected to the center connector on the dryer power block. No ground strap is used in a 4 wire setup (grounded circuit). In the sample picture above the ground strap in folded over and is connected to the center connector but NO connection from it or jump to ground. The ground strap could also be removed if you wish as it is not needed in this installation.
