Question about GE Profile Harmony DPGT750EC Electric Dryer

Switching 3 prong cord to a 4 prong cord

What do I do with the green ground wire connected from inside the dryer to the ground connection? All the internet info tells me to reconnect it to the neutral but in their photos it is a white wire and on this machine it is a green wire. Do I leave it connected and also connect the ground wire from my 4 prong plug or do I disconnect it and add it to the neutral connection?

If theres a wire from the center terminal on the dryer terminal board going to the dryer case disconnect it,then Red & Black on the cord go to the outer 2 terminals on the dryer terminal board,the White goes to the terminal in the center between where you put the Red & Black wires this is the Neutral wire,then the Green wire connects to any metallic portion on the dryer case as this is the SAFETY Ground wire and also Red & Black can go on either outer terminal on the dryer terminal board as these are not polarity sensitive because its A.C. power so wire it on the dryer terminal board as in (RED-WHITE-BLACK) on the dryer terminal strip and connect the GREEN to any Metallic portion of the dryer case

SOURCE: connecting 4-wire cord to GE profile dryer

The following link explains how to properly install a 4-wire power cord to your appliance:

http://www.fixya.com/support/r793520-3_prong_4_prong_power_cord_conversion

The main difference between a 3-wire and 4-wire configuration is how the ground and neutral wires are terminated.

In a 3-wire configuration the wires are terminated together at the terminal block via a ground strap.

In a 4-wire configuration the two wires are independent of one another. Match the corresponding colored wires at the terminal block and attach the ground wire to the ground lug on the equipment cabinet.

I hope this explains it well enough for you. If you still have questions, please let me know.

SOURCE: my dryer came with a 3 prong plug but the house i

GREEN is always ground if you are going by United States wire color code. BLACK is HOT and is carrying 120VAC on it. RED is the other HOT lead. If you are attempying to convert from a 3-prong cord to a 4-prong, the following link explains how:

http://www.fixya.com/support/r3575913-installing_a_220_vac_appliance_cord

The main difference betwen the two configurations is how the Neutral (WHITE) and the Ground (GREEN) wires are terminated at the terminal block. In a 3-wire configuration neutral and ground are terminated together via ground strap. In a 4-wire configuration, these two wires are independent of each other with no ground strap. Neutral is terminated with neutral and ground gets terminated to the equipment cabinet.

Read through the link provided and let me know if you have any questions. I hope this helps you.

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.. The links below might enlighten you further on this matter.

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 am switching from a 3 prong cord to a 4 prong cord. I see that the 3 prong cord is grounded seperately from the cord itself, i have hooked up 3 wires of the 4 prong cord but i still have the green ground...


You can connect the green ground to any bare metal on the dryer. Just look for someplace that is in reach of the wire or drill and tap a screw to attach it to.

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!

Dryer outlet does not have common wire.


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.

Change fr 3 prongs to 4


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!
