SOURCE: changing 3 wire to 4

If you had a 3 wire system and need to adapt your drier to a 4 wire system.. here is how you do it.. Your 4 wire cord should have the following colored wire ends.. Red, Black, White and Green.. The red and black are the power leads and should be attached to the red and black terminals on the back of the drier.. The White wire is Neutral and should be terminated on the white terminal of the drier.. The green wire is Ground and should be attached to the nearest frame or chassis screw at the point of entry into the drier.. If you are using a metal cable clamp as part of a feedthru system to get the cord into the drier.. you can attach the green wire to one of the screws on that.. but that should be done only if you canot find a suitable frame ground screw near the terminal block.. Hope this helps...

Remove the wire or metal strap from the center terminal to the dryer frame. Put the white wire on the center terminal. Put the green wire on the dryer frame. Red to one outside terminal, black to the other.

SOURCE: I need to change the dryer power cord on my Amana

The two wires on either side of the power cord are your HOT leads. They are the voltage carrying conductors. These two wires will connect to the terminal block on the RED and BLACK wires. The middle wire is NEUTRAL and goes to the WHITE wire at the terminal block. Now...with a 3-wire configuration you will need to connect a grounding strap to the neutral wire and ground it to the grounding lug of the appliance. The following link explains:

The main difference between 3 and 4 wire configuration is how the neutral and ground wires are installed. In a four wire configuration these two are independent of each other. In a 3 wire configuration ground and neutral are connected together.

If you have any questions about this repair, please ask me. I hope this helps you.

SOURCE: changing dryer plug

These two pictures illustrate the power wiring on a the terminal of an electric dryer. The one on top is the old-style three-wire configuration. Most people have this type in their homes. New code changes, though, require that dryers now have a four-wire cord, shown on the bottom.
Besides the number of wires in each cord, there are two important things to notice. First, in the four-wire configuration, notice that the dryer's grounding strap is folded back on itself. The whole point of the four-wire cord is to separate the ground from the neutral. The green wire (the "new" extra wire in the four-wire cord) is attached to the dryer cabinet. In the three-wire configuration, the grounding strap is left intact and the neutral and ground are tied together.

Sure hope this helps you find a resolution to your delimma! Best wishes.

GTDX100EM1WW GE Electric Dryer smells hot and electric cord is very hot Problem not present on air dry. Vent is connected and air blows through. Cord is quite hot to touch at the outlet.

Usually the motor, if you're not experienced, better to have a service person come out. Almost always the motor in the dryer that causes this

Have ge dryer changing from 3 prong power cord to four prong need diagram

The main difference between a 3-wire and 4-wire configuration is how the Neutral and Ground wires are terminated at the temrinal block. The following link explains:

In a 3-wire configuration Neutral (WHITE) and Ground (GREEN or BARE COPPER) are terminated TOGETHER at the terminal block via a ground strap.

In a 4-wire configuration these two wires are independent of each other are NOT terminated together.

If you have questions, please let me know. I hope this helps you.

How to install a 4 wire cord on a 3 wire dryer

This is a common question we receive and a common mistake most every general contractor makes that we work with. With a 3-wire system your neutral terminal will have a copper clad or aluminum strap or green wire connected between it and the frame. You need to remove this when changing to a 4-wire cord.
Terminate the wires from your new 4-wire cord as black to black terminal, white to white terminal, red to red terminal and green to ground screw on frame. This is the other end of that strap or green wire you need to remove from the white (neutral) terminal.
When changing to a 4-wire cord it is very important to remove the strap or wire that connects between the white terminal and the dryer’s frame. If you do not remove this, your neutral or grounded conductor will allow electricity to flow through your dryer’s frame and shock you each time you touch your dryer.

How do you install a 3 prong power supply cord to a GE Dryer?

you can't change the power supply cord.
the cord came with the dryer is 240v. the three prong is 120v. the dryer will burn up. if you change the power cord without changing the regulator , motor, and the heating element.
you need to get a electrician to run a 240v double breaker from the panel to the dryer.
