David for Model Number Dryer Terminal Block 134037400 My wall outlet and the power cord have four prongs; (2) hot wires, (1) neutral and (1) ground. The Dryer Terminal Block 134037400 has three connection points. I understand which wires from the power cord attached to each prong on the terminal block. My question - Does the power cord ground wire just connect to the green wire attached to the dryer chassis?
Answer Hello David, Green is always chassis ground in appliances. The chassis ground is there so if a hot wire contacts ground, the breaker will discontinue power to the unit instead of allowing voltage to ride on the chassis until someone touches it and becomes the ground that opens the breaker. Be aware that on some models, there may be a copper strap that goes from the center terminal to ground. On this design, the green wire can be connected with the white on the center terminal. If there is no strap to ground from the center terminal, the green wire has to be grounded at the screw hole with the ground symbol ? beside it. Read More...
