Had to change out the electric cord but the new one has 4 red black white green, dont know where to put the white and green is ground and white is netrual...

On a three-prong cord there is a black, a red, and a white wire. The black and red are hot and the white is neutral (return). Return on the dryer is also in these cases the ground which is shunted to the netal case of the dryer. On a four prong, you have black, red, white, and green wires. The black, red, and white are the same as before, but the green is a direct connection to the dryer case for ground. This ensures proper grounding and was first introduced in to mobile home installations, where the electrical system may not always be properly grounded.

Your new 3 prong power cord needs to be wired up just like the 4 prong you just dont have the seperate ground . in the use of a three wire cord ground runs thru neutral .Hook black to black on the terminal block on unit. hook red to red on the other side of block and white to white or green in the middle reinstall the cover ....Plug in and your ready to dry

red and black are the 2 power phase wires and go on L1 and L2 terminals or on an inline power block the 2 outer terminals(polarity)doesn't matter,then white is the center or N-neutral terminal, then green or green/yellow stripe is chassis safety ground and is connected to the metal frame of the unit

The following link explains how to correctly install a 220VAC appliance cord:

Match the corresponding colors at the terminal block, making sure the Neutral (White) and Ground (Green or Bare Copper) wires are NOT terminated together.

If you have any questions, please post back and let me know. I hope this helps you.

Get an qualified person to do it. If you do not have any idea how to do it, you are better off having someone else do it. If you have a 3 prong receptacle, you need a 3 prong pigtail. And if you have a 4 prong receptacle, the dryer needs a 4 prong pigtail. The green is ground, white is neutral, red and black are both hot (L1 and L2). If you put a 4 prong pigtail on, remove the ground strap between the center post and the case. The green ground goes on the case, white neutral in the center, black or red to the left, what's left on the right. You can interchange the red and black but NOT the white or green. If you use a 3 prong pigtail, the center is the neutral (same as white on the 4 prong) and you will need the ground strap between the neutral (center) and the case. The wires do NOT cross over on a 3 prong pigtail.

black to black lug white to white lug red to red lug green to ground(any bolt that is attached to body of 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.

The white wire goes in the middle between the 2 hot wires.

hi. thanks for the question. the red to red black to black white to white green to the frame of dryer to ground. thanks the appliance doc please rate this answer

• green = ground (attach directly to the case, should be a green painted screw near the opening
  
• red = hot 110v connect to the red on the dryer
• black = hot 110v connect to the black on the dryer
• white = neutral connects to the blue (only if the blue is in the middle)
• neutral is always in the middle with a hot wire on either side of it.
• also make sure all the connections are tight

let me know if you need more help Mike
