I changed the power from a 3 prong power cord to a 4 prong power cord I put the green and red wire on the same terminal and screwed it in and plugged it in, I never grounded the green. Now I get nothing from the washer or dryer did I mess up something, is it fixable

4-WIRE SYSTEM CONNECTIONS

Remove the ground strap screw from the terminal block support. Fold the ground strap over so both ends of the ground strap will be attached to the center terminal block post.

Connect the neutral (white) conductor of the cord to the center (silver) post of the terminal block. Connect the grounding (green) wire of the cord to the terminal block support using the ground strap screw.

Connect the red and black wires of the cord to the outer posts of the terminal block.

Be sure the terminal block nuts are on tight. Secure the power cord in position. Tighten the strain relief screw(s) in order to clamp the strain relief to the cord. Replace the terminal block cover.

When replacing a 4 prong cord with a 3 prong cord you put black and red wires to the outside posts of your terminal block. The white wire from your three prong dryer cord goes to the center of your terminal block. The yellow and green wire from the dryer go together and attach to the cabinet ground.

ok,, easy one,, unplug, take the cover off of the terminal cover,, take your old cord off, on the 4 prong you will have a red, black, white,and green wire,, matche the colors up red on right, white in middle, black on left, the green wire will go on a green screw that is near the terminal block with a white wire going to it, take the white wire off and put it with the white wire on the terminal block,, screw the green wire to the green screw,, and relpace cove and your done

Your four prong cord has 4 wires. Black,Red,Green and White.
Remove the 3 prong cord from the dryer.
The Black and Red wires go to the outside terminals on the dryer. The White wire goes top the center terminal. The Green wire goes outside the terminal cover to any nearby screw for grounding.

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

First make dryer is unplugged !!!!!!!!! remove cover near cord entrance to dryer, you will notice 3 terminals. you should also see a green screw close by. there may be a wire or strap connecting center terminal to the green screw or ground. remove wires from terminals and remove strap from center to ground screw. connect new cord in the following order. green wire to green screw or ground, white wire to center terminal, black wire to left terminal, and red wire to right terminal. now you are done put the cover back on. I'm glad you asked this question. this is a very popular question. Your new 4 Prong cord is up to current code. I'm happy to see people updating there appliances to current code and making their homes safer. Thanks

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.

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.

If converting from a 4-prong to a 3-prong configuration, the wires are terminated at the terminal block as follows:

RED (hot) - to RED
BLACK (hot) - to BLACK
WHITE (neutral) - to WHITE
GREEN (ground) - is terminated to neutral by using a common screw at the terminal block, or by using a ground strap from the neutral terminal to a ground on the equipment casing.
