The following link explains how to convert from a 3-wire to 4-wire configuration and vice versa:

http://www.fixya.com/support/r793520-3_prong_4_prong_power_cord_conversion

The main difference between these two configurations is how the ground (green or bare copper) and neutral (white) wires are terminated. In a 4-wire confugration, the ground and neutral are independent of each other. In a 3-wire configuration the neutral wire will be grounded at the terminal block in back of the dryer by a ground strap.

Since you have an existing dryer outlet with a 3-prong configuration, the easiest solution would be to replace the dryer cord with a 3-prong cord to match your outlet. No need to rewire your house. A new cord can be purchased at an appliance parts retailer or hardware store for about $20 or less.

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

You can replace the 4 prong with a three prog cord found at Lowes etc.

First, disconnect the black wire, one of the "hot" connections, from the left side post by removing the terminal screw. This is one-half of the 240-volt connection.
Next, disconnect the red wire, another of the "hot" connections, from the right side post by removing the terminal screw. This is the other half of the 240-volt connection.
Then, disconnect the white wire from the center connection. It is used for the neutral connection.
Now, disconnect the green wire from the machine case by unscrewing the green screw.
The next step is critical to return your electrical connection to factory condition before installng the 3-prong cord! Locate the white machine wire that is now connected to the neutral (center) screw terminal. Disconnect it from there and install it under the green ground screw.Connect the outer two wires (hot wires) to the outer two screws, obviously, one on each screw.
Now connect the center wire (neutral) to the center post. You'll notice the white machine wire is now the case ground connection, unlike the 4-prong cord connection in which the green wire from the cord makes the ground connection.

Tip

Rewiring 4 to 3 wire plugs Information.


So you have an, ahem... problem....you have a Code compliant dryer (with it's 4 wire cord and plug)....and have moved into an older home that is not Code compliant (with it's 3 prong receptacle outlet)....and this is fairly common.

At this point - you have two choices....replace the wiring from the dryer's breaker to the receptacle with all new 8/3 with ground romex (it more then likely only has 8/2 with ground now)....and replace the receptacle with a 4 prong grounding receptacle to match your dryer's cord....OR - as an alternative - you can replace the cord on your dryer with a 3 prong cord to match the existing dryer receptacle outlet.

Out of the 2 choices....the first one will bring the old wiring in the home up to current Codes (all NEW homes must have this 4 wire/4 prong set-up per Code...but older homes are grand-fathered)...but it is clearly the most involved, time consuming and most costly approach...and it is recommended only an electrician do this work. If this approach is taken....your dryer cord can stay as is...it will now fit the new receptacle outlet with no modifications.

The second approach - is to pick up a 3 wire 3 prong cord at your local hardware store to match the existing 3 prong receptacle.....and replace the 4 wire cord on your dryer with it. Although this is the least desireable - it is an allowed approach because this is an older home with existing wiring. This is a much less involved approach...all you need to buy is the 3 wire dryer cord (they come all ready to go) remove the 4 wire cord and install the 3 wire cord to your electrical connections at the back of the dryer. Hopefully...when the 4 wire cord was installed on your dryer, the ground strap wasn't removed completely (this is a metal strap that will connect the white wire to the metal frame of the dryer)...because now you will need to re-use the ground strap. For more on this....see the images of the differences of the 3 wire and 4 wire dryer hook-up at:
http://www.applianceaid.com/general.html#3to4

NOTE: the only real difference between the 3 wire cord and the 4 wire cord is now the white neutral and the ground are kept seperate in a 4 wire..the green ground will connect directly to the dryer frame....where in a 3 wire there is no seperate ground wire - ground and neutral are one and the same...the ground strap connects the frame to the white neutral. The 4 wire permits a better safety measure...in the event of an electrical problem (ground fault) in the dryer...the fault now has a seperate path to your panel's ground...and less chance of a shock from touching the metal frame of the dryer.

The choice of how to proceed is up to you....if you go with completely updating the dryer wiring from the breaker outward...I recommend an electrician do this work for you (it's about an hour's work...plus materials). Then your exisiting dryer's 4 wire 4 prong cord can stay as is....the electrician will install a 4 prong receptacle made to fit your cord.

If you go with simply replacing the dryer's cord....changing it to a 3 wire so it will fit the receptacle...make sure the ground strap is re-utilized as seen in the images at the site above.(also make sure all work is done with the dryer breaker (or fuse if a really old home) off before starting any work. If you change the cord yourself...make sure to reconnect in exactly the same manner as the previous cord was connected...(make a note on paper or take pictures so that there are no mistakes)..and that you tighten the nuts securely to the posts once the wire lugs are on them. Where you state you do not have a background in electrical work...you can have an electrician change this cord for you...(typically in under a half-hour)....or you can do it yourself - by carefully following the pictures.

The choice is yours...if it was me - I'd change the wiring from the breaker outward...making the older home meet today's current Codes and be complaint for this dryer..and then you wouldn't need to change a thing on the dryer....but you can go either way....Codes allow this grandfathering in older homes with existing wiring.

Four prong cord three prong outlet


Ok this is how you will wire the three prong to the dryer.

You have 2 wires that are gold/brass in color, those are the hot wires.
You have 1 wire that is crome/silver in color, that is the neutral

On back of fryer where you wire it you put the wires on like this right to left Gold/brass hot, silver/nuetral, then the other hot wire.

On back of dryer you will have screws from right to left this color gold/brass, silver/crome, then gold/brass again.

If you do have a 4 wire cord the extra wire is ground and you screw that to the machine body.

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.

Replacing eletrical cord to a four prong cord. there are only three connections. there are no color codes to make it easier. How do I replace the cord


Dryers are 220 Volts AC and the outer connections inside the dryer are "hot" or live legs (black or black and red wires) of the circuit, while the center one is typically the neutral (white) wire.

The difference between a 3 prong plug and receptacle and a 4 pronged one is simply that the 4 prong plug and receptacle has a dedicated ground integrated into it, whereas the 3 prong plug is what's commonly referred to as an ungrounded circuit. There is no dedicated ground in a 3 prong plug and receptacle that makes a separate, grounded connection from the dryer to the receptacle to the electrical panel of the house.

Also, please look at either the back of the dryer for a basic wiring diagram, or look inside the access panel where the dryer cord is connected. There should be indications as to what each terminal is for, as I stated, typically the outer connections are the "hot" while the center one is typically the neutral. If you notice a strap running from one of the dryer's connection terminals to the cabinet/frame of the dryer, that is the neutral. The others are the hot terminals, which are the outside ones.

Look for a green grounding screw inside the dryer's electrical connection section. That is where the green wire on the cordset would be connected/terminated.

If you wish, you can get a free Installation Guide for your dryer at the following link to download and/or print out at:

http://www.managemyhome.com/mmh/lis_pdf/INSTL/L0520950.pdf

It will show you the connections for both a 3 and 4 wire cordset.

Hope you find this Very Helpful and best regards!

Changing from a 3 prong to a four prong


grasshopper_2.gifWiring 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.

tn_3cord_dryer_terminal.jpgtn_4cord_dryer_terminal.jpgThese 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?
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.
tn_3prong_dryer_outlet.jpgtn_4prong_dryer_outlet.jpgIf 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.

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

Changing four prong dryer to three prong outlet


use the ground on the machine.....There are 3 wires on the terminal block if you notice there is a grounding strap off the center post this will act as your ground to the machine back in your panel box the center post leads to ground anyway the other 2 are hot leads (240vac) use the 3 post you will be fine. you will be grounded let me know if you have any problems

If your dryer came with a 4-prong plug, do not change it. For the very reasons you quoted with the article, you may screw up the 110v accessories required of your appliance (like the clock or digital display). It is best to change the household outlet to a 4-prong type. Just make sure your wiring is correct. You will need a neutral on the 4th leg, which means you will probably have to run new wiring from the outlet to the distribution panel.
