I need to switch my three prong power chord to a four prong

An electric dryer has an opening in the back, older units use a three prong cord, there will be three posts to attach cord, newer units have four prong cords, Bought separately. there will be four posts to attach, double grounded cord.

Hi,

Here is a tip that will help you with changing your dryer plug.

Dryer Cord and Wiring Dryer 3 Wire or 4 Wire

This is probably fixable as you probably hooked the cord up wrong and it arced and likely blew the breaker before much was damaged. The 3 prong cord has obviously, 3 wires. As long as you get the middle wire in the the cord hooked to the middle terminal on the dryer, the other two wires can go to each of the outside terminals, no matter which one goes where. Correct the cord and you will probably be in good shape.

In most all cases, the 4 prong plug has to lines of power, one line neutral, and finally a ground. The only thing you can do is eliminate the ground. You still need to run a ground wire from the unit to some sort of positive ground for safety reasons. Do not leave the unit ungrounded. You can really get hurt or worse.

Helo,
Yes you can reconnect it to the original place and everything will be fine...

If you desire to convert an appliance from a 4-prong to a 3-prong, make sure you reconnect the bonding strap and/or ground wire to the Neutral (white) wire at the terminal block.

Connections

Old

New



Picture shown is for a range cord but is exactly the same for a dryer connection.

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.

The green wire goes to the frame of the machine. White is in the middle and black on black and red on red. Check out these pix

Wiring in a new power cord for your electric dryer? Upgrading your electric dryer outlet from the old three-prong to the new four-prong outlet? Well, grab hold of those two large lumps at the base of your spinal cord and let's romp through the wild and wacky world of dryer cords and outlets.

These two pictures illustrate the power wiring on a the terminal of an electric dryer. The one to the left here 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 to the right. These are just just thumbnail pictures that you can click for a larger view. But I'll bet you already figured that out, didn't you?

If you need to re-wire the outlet, these pictures will explain the anatomy of the three-prong (left) and four-prong (right) outlets. Once again, these pictures are just thumbnails--click 'em for a larger view.
