White Ground Wire not attached to power cord

Changing my power cord from 3 to 4 prong cord.  Had no trouble removing and reattaching the wires.  However, from the inner wiring of the dryer has a white wire that is attached to the frame.  This attaches to where the green ground wire needs to attach.  So the question is this...can I attach the white with the green since both seem to be ground wires?

    The images did not post for my computer (have a mac).  Just want to make sure I understand what you are saying.  Keep the red, white and black attached, do NOT reattach the white wire from the the dryer with the green wire (the green is from the new cord)?

You want to go from THIS...
White Ground Wire not attached to power cord - 26c1554.jpg


to THIS.....


0b7c713.jpg Use the chassis for a grounding point.
In the bottom picture you can see ( L2 where BLACK wire is connected )
(N is neutral where WHITE wire is connected ) ( L1 where RED wire is connected )
( Green is GROUND and connects to the case of the dryer )
Besides the number of wires in each cord, there are two important things to notice. First, in the 4-wire configuration, notice that the dryer's grounding strap is folded back on itself--the whole point of the 4-wire cord is to separate the ground from the neutral. In the 3-wire configuration, the grounding strap is left intact--neutral and ground are tied together.

If I were doing this change I would remove strap and put ground
( GREEN wire ) where strap is shown sticking out - much better.


Thanks for using FixYa!!

    correct... do not combine the green/white. That defeats the purpose of the 4 wire code.

    Green goes to chassis ground.

How do I replace a 4 prong cord on a magic chef stove to a 3 prong cord


The stove has three terminals and a ground post. On a 4 wire cord the green wire goes to the ground post the white wire goes on the center terminal and the red and black can go to either one of the two outer posts as long as one is on one terminal and one on the other. In a three wire system the case ground has to be attached to the center post where the center wire of the cord is attached. In a 4 wire system this case ground is usually removed or bent out of the way. If it is still attached from the center terminal to the ground post then all you have to do is attach the center wire to the center terminal and the other two wires to the other two. If it has been removed then you must reattach the ground strap to the center terminal or if it is missing attach a ground wire of some type to the center termonal and the ground post.

Tip

3-prong to 4-prong Power Cord Conversion.


This advice is on how to correctly install an ELECTRIC DRYER or ELECTRIC RANGE 220-240VAC power cord (US Standards).

3-Prong or 4-Prong – The Difference:

3-prong color code:

BLACK (HOT – 110-120VAC) – May also be referred to as L1
RED (HOT – 110-120VAC) – May also be referred to as L2
WHITE (NEUTRAL – 0VAC) – Usually grounded to the equipment frame via a jumper wire or metal strap.

4-prong color code:

BLACK (HOT – 110-120VAC) – May also be referred to as L1
RED (HOT – 110-120VAC) – May also be referred to as L2
WHITE (NEUTRAL – 0VAC) – DO NOT ground to equipment frame.
GREEN (GROUND) – Attach to equipment frame.

Which One to Use: According to the National Electrical Code (NEC), Article 250, installations after the year 2000, require the use of a 4-prong plug which incorporates a separate ground and neutral wire. If you currently have a home that uses the 3-prong receptacle and cord, you can continue to use it. You will have to upgrade to a 4-prong configuration, however, if you plan on relocating your current receptacle, or if the internal wires of the receptacle become damaged in any way and require repair.

Converting from 3-prong to 4-prong: Make sure you UNPLUG the appliance prior to any repairs. CAUTION: Voltages dangerous to life are still present even with the appliance turned off and still plugged in. Notably in the area of the terminal block where the power cords are installed. You will need to remove the old cord by following these steps:

  1. With the appliance UNPLUGGED, remove the access panel on the back of the unit where the power cord enters.
  2. With the cover removed, you will see a terminal block where the power cord is attached. The terminal wires will be colored with the WHITE wire in the middle, and the BLACK and RED wires on either end. NOTE: There should be a green jumper wire or metal bonding strap attached to the NEUTRAL (white) terminal wire.
  3. Remove the terminal lugs holding the old power cord wires in place. CAUTION: Use care not to drop any nuts or screws inside the appliance.
  4. Remove the bonding strap or ground wire from the Neutral terminal lug. NOTE: If disconnecting a ground wire, make sure you re-attach it to the appliance frame.
  5. Loosen the screws on the strain relief connector that holds the power cord in place and remove old power cord. NOTE: If your appliance does not have a strain relief that clamps down and hold the power cord in place, it is highly recommended that you install one. This prevents chaffing of the power cord against the appliance casing, and prevents the terminal wires from being pulled and broken loose. This could pose a potential shock hazard or cause damage to the appliance.
  6. Install new power cord by threading it through the strain relief connector and tighten down the screws.
  7. Connect the new power cord to the corresponding colors at the terminal block (Black goes to Black, Red goes to Red, White goes to White). The difference is going to be a Green (ground) wire that will connect to the appliance frame. There’s usually a green grounding screw for this. NOTE: If you disconnected a green grounding strap in Step 4., you can connect these two wires at the same point.
  8. Re-install access cover. Turn off the service breaker to the appliance PRIOR to plugging it back in. With the breaker in the off position, plug the appliance in, and THEN turn the breaker on. In the event, something was wired incorrectly, it is far better to have your hands away from the receptacle and controlled from a distance. Safety first.

Kenmore 700 dryer with a three prong cord is being converted to four prong. Is there a drawing of what wires by color going to the proper screw location?


There's a ground strap wire (green/yellow) attached to the dryer cabinet and connected to the center terminal where the white neutral wire of the power cord is connected. Disconnect this ground strap wire and remove the 3-prong power cord from the terminal block taking note where the wires are connecedt to. Connect the 4-prong power cord in the same way same wire colors of the 3-prong cord are connected to the terminal block. Connect the ground strap wire to the remaining fourth wire (green/yellow). Just do the reverse when converting 4-prong to 3-prong. The link below might enlighten you further on this matter.

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.

These steps will work for nearly all appliances that require a 220-240VAC power cord conversion. The power cords are usually rated at 250VAC, 30 amps, and are carried by any hardware store or appliance parts retailer.

ADDITIONAL NOTES:

1. 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.
2. On some newer appliances, it is REQUIRED that you use a 4-prong plug in order for the timer or clock circuits to function properly due to the way they are configured. Refer to your owner’s manual for the correct recommendation. Even if you currently have a 3-prong receptacle, you still may be required to upgrade to a 4-prong if you encounter this situation.
3. In many circumstances, new appliances are NOT sold with the power cord due to the various power configurations in homes. Always refer to the contents description on the shipping container the appliance comes with to see what additional items or tools may be required for installation.
