I just moved and have a three-prong dryer and a four-prong outlet, and you can indeed switch out the cords. Just buy a new, 4-prong pigtail and then the three wires go with their corresponding color connections and the fourth is a ground wire, which connects to a metal plate on the outside of the dryer. Mine has a "ground" symbol on it - kind of a pole or vertical line with three horizontal lines under it. You should be able to find it and reattach it without too many problems, I did and I'm a 21-year old female who had never even seen the back of a dryer until recently! My problem now is that I just moved (hence rewiring the dryer!) and apparently a piece of lint fell down against the heating element. Now I have to find a way to get the back and sides (all connected) off of this dumb dryer . . .

WHy are you switching the cord from a 3 to a 4? If the dryer came with a 3 prong cord and its a 3 prong terminal block, then i dont think you can change it to a 4 becuase you will short circuit. DOes the terminal block where your cord was hooked up have 4 terminals. Each termial can only have one lead/wire to it. check your circiut breaker panel? Is the circiut breaker tripped?

4-prong to 3-prong Power Cord Conversion.


On a 4-prong power cord you have 2 hot wires, one neutral wire, and one ground wire. On a three prong cord, you have 2 hot wires and one neutral/ground wire. The difference is the on four prong the neutral wire goes to electrical neutral bus in the breaker panel and the ground wire goes to the ground bus in the breaker panel. Since the neutral and ground buses, although separate, both go to physical ground, on a three-wire setup, you are just putting the neutral and ground wire together, Most dryers actually have a place at the pigtail connection to do just that.

I need to change my 3 prong to a 4 prong


Unplug the dryer then remove the terminal block cover and disconnect the 3-prong cord from the dryer. Note that the cord has red , black, and white wires but sometimes the red and black wires are both replaced by same color wire, usually gray and can switch places. There's also a ground strap wire also connected to the center terminal together with the white (neutral) wire.

Get yourself a 4-prong cord and note that it has red, black, white, and green/yellow wires but sometimes, like the 3-pronged one, the red and black wires are both replaced by same color wire, usually gray and can also switch places. All you have to do now is connect the 3 wires in the same manner they are connected as 3-prong cord to the terminal block. The ground strap wire now just need to be connected to the remaining 4th wire, the green/yellow wire instead of the center terminal together with the white (neutral) wire. Reinstall the terminal block cover and it's done.

It can be observed that converting a 3-prong cord to 4-prong cord is merely splitting the neutral line and the ground thereby increasing the number of prongs from 3 to 4 whereas, on the other hand, converting a 4-prong cord to 3-prong cord is merely joining the neutral line (white) and the ground (green/yellow) thereby reducing the number of prongs from 4 to 3..

I have a four prong clothes dryer plug that needs to go in a three prong outlet - 220v. Any ideas?


It's either you convert the 3-prong outlet to 4-prong or the 4-prong cord to 3-prong. But the latter is easier and more feasible. Unplug the dryer then disconnect the 4-prong cord from the dryer. Note that it has red, black, white, and green/yellow wires but sometimes the red and black wires are both replaced by same color wire, usually gray. The red and black wires are lines L1 and L2 reversibly, meaning they can switch places, while the white and green/yellow wires are the neutral line and ground, respectively.

Get yourself a 3-prong cord and note that it has red , black, and white wires but sometimes, like the 4-pronged one, the red and black wires are both replaced by same color wire, usually gray and can also switch places. All you have to do now is connect these 3 wires in the same manner they are connected as 4-prong cord to the terminal block. The wire strapped to the dryer cabinet and connected to the green/yellow wire of the 4-prong cord wire is now left hanging. The last step is to connect this hanging strap wire to the same terminal on the terminal block (center) where the white wire (neutral) is connected and it's done.

It can be observed that converting a 4-prong cord to 3-prong cord is merely joining the neutral line (white) and the ground (green/yellow) thereby reducing the number of prongs from 4 to 3. On the other hand, converting a 3-prong cord to 4-prong cord is merely splitting the neutral line and the ground thereby increasing the number of prongs from 3 to 4.

I have a 3 prung male plug, and a 4 prung female plug. Can I switch the 3 male plug to a 4 male plug?


Hi, and yes you can, its done all of the time. You want to change the plug on the wall, not the cord. That is the way it is done. Very simple. Turn off breaker to the 4- prong. Go to any hardware store such as home depot and get the 3 prong 220 volt female plug, both are the same volts, just made for different cords is all. The male is on the cord. On the 4 prong female plug thats on the wall, just loosen all 4 screws. 2- wires are hot, either black in color, a black with a piece of white tape on it is the neutral, and a bare ground which is much smaller. When installing the 3 prong female, you will use all 4 wire to. 2- hot, ! neutral, and a screw for the small bare ground. There will be a drawing on how to connect the wires with the new plug if you are not sure. Normally, there are 3 black wires, 2 hot , 1 neutral. Some times there may be 2 blacks and 1 red. A black and red will be hot.I am sure they will all be black. The plug is marked on it. It will have L-1, L-2, N, and Ground. When you remove the 4 prong female, it will be marked the same. Be sure the power is off! L-1 and L-2 are hot, and the 3rd is N or neutral. Then the small ground. Very, very, simple to change and to know which is which. The terminals on the plug are colored also. The 2 that are copper colored are for the hot wires. The brass or silver is the neutral. And you will see the ground screw. I hope I haven't confused you, it is very easy. Just when removing the wires to the old plug on the wall, which should be a 4-prong female, the 2 wires on the right and left side of the plug are going to be the 2 hot wires. The other large black is the neutral goes to top or bottom, its marked like I said with a N. and a small bare ground. Always change the plug on the wall to fit the dryer from 3 to 4, or 4 to 3. They are both 30 amp plugs, 220 volt. Very easy, you can do this!! Please rate me on my help to you.
Sincerely,

Swich 4 cord to 3 cord plug in


To switch from a 4 prong to a 3 prong. First remove 4 prong cord, save screws you will need them. Look a 3 prong, it will be flat with 3 wires next to each other with metal fittings on the ends. The 2 outside which are hot wires go to the outside screws on the block, and the center which is neutral goes in the center. The only difference in the cords is the 4 prong has a ground, in new construction this is code. You don't need a ground if house is wired for a 3 prong.

The dryer has a four prong male plug and the outlet is a three prong female - which do I change? the dryer cord is the easiest, but how do I connect the leads?


4 PRONG PLUG WIRING: 2 HOTS(RED&BLACK) 1 NEUTRAL(WHITE) 1 GROUND(GREEN). 3 PRONG PLUG WIRING: 2 HOTS&1 NEUTRAL. YOU MUST USE 2 HOTS & 1 NEUTRAL ON A 3 WIRE PLUG. THE GROUND WIRE(GREEN) WHICH IS HOOKED TO FRAME OF THE DRYER IS NOT USED ON OLDER 3 WIRE PLUGS. IT IS AN ADDITIONAL SAFTEY GROUND ON NEWER MODEL 4 WIRE PLUGS.

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.

I need help in changing the 4 prong to a 3 prong cord


It would be a better and safer idea to change the receptacle from a three prong to a four prong. You would also be in compliance with the electrical code. That being said, here is the info you will need to go either way.

Trying to hook a 3 prong hook up with 4 prong cord how do i do it?


A 3 prong plug is for 240 volt (hot-hot-ground) the 4 prong plug is for 120/240 volt (hot-hot-neutral-ground). If your device requires a 4 prong plug, it is not a good idea to connect it to a 3 prong circuit (you will create a possible lethal electrical condition). If your device requires a 3 prong connection, a 4 prong cord can be used by not connecting the neutral (white wire). If you have any questions, let me know.
