What size screw is used for 3 prong outlet in LG WKE100HWA dryer? Can't unscrew left and right screws to install cord.

Yes. Putting on a new cord is simple. There is a plate covering the cord that is on there now. Remove the two or three philips screws holding it on. Get a new cord at an appliance store. Use a nut driver to detach the old cord. Hook up the new cord with the colored prongs in the same places as the old. The green will be the one that is missing. Replace the green screw so it is not lost. Be sure to install the cord protector so the sharp edge does not slice through your new cord. Good luck.

Un screw the 2 hex screws from the back of the dryer where the cord goes in.

There will be 3 screws that connect the cord to the dryer, loosen or remove them to remove the 4 prong cord.

A hardware store will carry the 3 prong cord you need, tell them it is for a dryer.

Re-connect the 3 prong cord to the dryer.

Plug in and test after you have installed the new cord.

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.

Unplug the dryer and pull it away from the wall.

On the back of the dryer near the top you will see a metal cover, usually just above where the cord comes out.

Unscrew any screws in this cover, usually only 1 1/4 inch or 5/16 inch screw that may also have a phillips or common screw head.

Once this cover is removed observe the cord going to the back of your dryer. There will either be 3 wires connected to 3 posts or 3 wires connected to 3 posts and one wire connected to the cabinet.

Remove the wire connected to the cabinet first.

Next unscrew the 3 screws holding the plug onto the terminal. Depending on how the end of your cord is made you may be able to just loosen these and pull the cord down or have to remove them completely. Do not drop these in the dryer!

Now just replace the cord with the new one and refasten the screws. Make sure they are extremely tight where the cord connects to the terminal block.

If you have a 3 prong cord with 3 wires the middle wire must go to the middle terminal and the other 2 can go on either side.

If you have a 4 wire cord the white wire will go to the center terminal, the black wire will go on either the left or right post and the red wire will go on the left or right post. One wire per post!

The last green wire will attach directly to the back of the dryer, usually with a 5/16 screw. This is just your ground wire.

Hope this helps.

Four prong dryer cord connections to dryer:

- Red to far-left or far-right screw on dryer (doesn't matter which side)

- Black to screw on opposite far-side on dryer

- White to center screw on dryer

- Green to dryer grounding screw

Any questions, please let me know.

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.

First thing do you have a 3 or 4 prone cord?
For 3 prong, when looking at block where cord attaches you have a left, center, and right screws, attach just like cord 3 wires, left on left, center on center, right on right. The only thing different with a 4 prone is you have a ground wire which grounds to ground screw on dryer.

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!

There are no adapters. But a dryer will accept a 3 prong or 4 prong cord. The extra green wire just needs to be connected to any screw on the dryer casing. Some newer dryers have a screw there for it..or u can just use the closest screw avalable......usually the screw for the cover works good.
