Question about Dryers

1 Answer

I have a four prong cord to connect, I did connect all except for the ground. There is a white cord inside the dryer that is connected to the ground and now I'm confuse if that is ground wire or it needs to be connected with the neutral. Should I wire the ground with the white cord? What would the solution for this. ES

    What about the white wire that is inside and connects to the green screw already. Do I remove it and only use the green?

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.

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 convert my dryer from a 4-prong to a 3-prong power cord. I understand all steps of the installation except for the grounding wire. Since there are only three cords now I no longer have a...


On your cord, the outside leads are the hot leads, with each one carrying 120 volts. On a four wiire cord, the two inside lines are neutral and grounds. For a three wire cord to be used with four lugs, the middle wire connects to one of the middle lugs, and the inner lugs should be connected together, Normally, a drier comes with a bridging plate to connect the two lugs, and it is removed for a four wire cord, or left in place for a three wire cord. You can bridge the two terminals with a piece of substantial insulated wire. I have never tried to buy a bridging plate, but you might try Lowe's, etc. for one.
Best regards,

There could be two situations for you. For the wall outlet, you may have a four prong plug or a three prong plug. For a three prong plug the outlet has three prongs and the terminals inside match up with these prongs. The two slanted prongs on the top are the hot terminals and the red and black wires get connected to these (order doesn't matter but keep the wires matched up with the terminals on the same sides). The white wire is connected to the "L" shaped prong, the third lower prong. The bare copper wire is just bent out of the way. At the dryer for the three prong there will be three terminals 2 hot and one neutral. Usually, your dryer cord will have the neutral as the middle wire, but pay attention if your cord wires are color coded (where white will be your neutral wire). At the dryer there is a terminal which is connected to the frame of the dryer by a piece of metal. This is your neutral, connect your neutral wire from your cord up to this. The other two wires get connected to the other two terminals (order doesn't matter but keep the wires matched up with the terminals on the same sides). For the four prong its very similar but there is a small change, that bare copper wire is now used. The terminals on the wall outlet will line up with the prongs. The two vertical terminals on the left and right are your red and black wires. The "L" shaped prong is your white wire. Now the fourth prong, the one shaped like a semi circle is the terminal you connect that bare copper wire up to that is your ground. At the dryer for the cord (If its a four prong cord your wires should definitely be color coded). The terminal that had a connection to the dryer frame now will no longer have one. The terminal thats connected to the frame you connect the green wire to. The terminal that was connected to the "green wire terminal' is now the neutral terminal and your white wire gets connected to it. The other two terminals are where your connect your last two wires.

you nead to remove the green wire from the interior and tape it off.the whole point of the four-wire cord is to separate the ground from neutral,the green wire on the cord is attached to the cabinet.

Replacing eletrical cord to a four prong cord. there are only three connections. there are no color codes to make it easier. How do I replace the cord


Dryers are 220 Volts AC and the outer connections inside the dryer are "hot" or live legs (black or black and red wires) of the circuit, while the center one is typically the neutral (white) wire.

The difference between a 3 prong plug and receptacle and a 4 pronged one is simply that the 4 prong plug and receptacle has a dedicated ground integrated into it, whereas the 3 prong plug is what's commonly referred to as an ungrounded circuit. There is no dedicated ground in a 3 prong plug and receptacle that makes a separate, grounded connection from the dryer to the receptacle to the electrical panel of the house.

Also, please look at either the back of the dryer for a basic wiring diagram, or look inside the access panel where the dryer cord is connected. There should be indications as to what each terminal is for, as I stated, typically the outer connections are the "hot" while the center one is typically the neutral. If you notice a strap running from one of the dryer's connection terminals to the cabinet/frame of the dryer, that is the neutral. The others are the hot terminals, which are the outside ones.

Look for a green grounding screw inside the dryer's electrical connection section. That is where the green wire on the cordset would be connected/terminated.

If you wish, you can get a free Installation Guide for your dryer at the following link to download and/or print out at:

http://www.managemyhome.com/mmh/lis_pdf/INSTL/L0520950.pdf

It will show you the connections for both a 3 and 4 wire cordset.

Hope you find this Very Helpful and best regards!

How to replace three prong cord to four prong cord on Frigidare electric dryer


Red, white and black go to the same terminals. If there is a ground strap connected to the white terminal, remove it. Connect the green wire to a ground. Any screw connected to the casing will do.
