Have you checked this link for instructions on wiring a 220-240VAC power cord?:

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

This is for US Standard wiring. Keep in mind, if your home was built after 2000, you are required to have a 4-prong style plug and receptacle to be within code. Please read through the link provided and let me know if you have any questions. I hope this helps you.

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 AN OLDER MODEL KENMORE DRYER MODEL NUMBER 86872800 AND A NEWER HOME HOME WITH 4 CONNECTORS DRYER HAS ROOM FOR THREE HOW DO I CONNECT NEW CORD


You have to replace the dryer's 3-prong cord to 4-prong. Get yourself a 4-prong cord then on the terminal block at the rear of the dryer, connect the wires of the 4-prong cord to where the same wire colors (red, black, and white) of the 3-prong cord connects to. The only modification needs to be done is on the green/yellow stripe wire that connects from the white wire terminal to the dryer's cabinet. Remove this wire (green/yellow stripe) from the white wire terminal then connect it to the same wire color (green/yellow stripe) of the 4-prong cord and you are done. The new wire configuration would then be red, black, and white on the terminal block and green/yellow stripe wire on the cabinet.

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.

I need to change out my 3 prong dryer power cord with a 4 prong dryer cord, but unable to figure out where the wires go on the new 4 prong power cord, because the one on there is grey and not color coded...




Changing from 3 to 4 wire hookup on a electric dryer:
Power cord help for 3 & 4 prong dryer cords
This is an example of a three wire connection dryer cord hookup. Notice that there is a ground strap connected from the common center terminal to the frame of the terminal block. Place the center wire of the cord on the center terminal [ one with the ground ******** it ] and the other two wires will be placed on the outer terminals and it doesn't matter which wire goes right or left. Get the center wire of the cord right and you are in business.
This is an example of the 4 wire dryer cord hookup. Notice that the ground strap has been removed from the terminal block frame and folded back onto the center terminal for storage. You can see the colors of the other hookups. TIP: White always to the middle.

Wire 3 prong cord


Electric Dryer How To Hook Up Cord pixel_trans.gifFor Three Prong Cords
the Center cord wire goes on the center terminal,
the left on the left ,
and the right on the right.

Note: There should be a ground strap or wire that runs from the center terminal to the dryer case.

For Four Prong Cords
the White cord wire goes in the center,
the Red on the Right,
the Black on the Left.
The green cord wire goes to the case or the external ground screw.

Note: Be sure to disconnect the ground wire or strap that runs from the center terminal to the case. In this Photo (A Whirlpool Dryer) I have ran the wire that runs from the center terminal, the Light Green wire, back to itself rather than cutting it off, just incase I need to put a 3 prong cord back on it some day. The whole purpose of this 3 prong / 4 prong thing is it separates the neutral from the ground. pixel_trans.gif pixel_trans.gif3 Prong Cord Whirlpool Dryer Example terminalblock.jpg 4 Prong Cord Whirlpool Dryer Example 4prongcord_small.jpg

Change fr 3 prongs to 4


They wire in the same except the green wire will go to a ground screw which should be right in the same area with a green color to it. If no ground screw, hook the green together with the white (center) wire. Hope this helps!
