I am converting a 3 prong dryer to a 4 prong plug. The wires inside the dryer are black/yellow, white and blue. The wires on the plug are white, black, red and green. I am assuming the green is the ground but which wires do I connect to the dryer?

I would attach the black wire to the black & yellow, white to white, red to blue & brown. The green wire is your ground wire and needs to be attached to the cabinet. On the connection where your white wire is located see if there is a copper strap that goes from the terminal block to the cabinet. If there is, you will need to remove that strap and attach the green wire to where the strap was attached to the cabinet. Hope this helps!

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..

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.

Hi,
Here is a tip that will help you with changing your dryer plug. Dryer Cord and Wiring Dryer 3 Wire or 4 Wire

The 4-prong plug has red, black, white, and green/yellow wires while the 3-prong plug has red, black, and white wires. The only difference is the green/yellow (ground) wire of the 4-prong plug which is attached to the dryer cabinet. All you have to do is connect the wires of the 3-prong plug in the same way the same wire colors are connected with the 4-prong plug then connect the terminal on the cabinet, where the green/yellow (ground) wire of the 4-prong plug is formerly connected, to the white wire of the 3-prong plug.

Yes, you can put a 3-prong plug in place of the 4-prong plug.

Hi .. I am posting a sketch of the 3 wire and 4 wire connections .. if you have any questions please get back to me ..

red and black go to the outer sides. white always goes in the middle and green just screws into the cabinet. so I would connect black to black white toi white and the blue to red and green to the cabinet

how do you change a 3 prong plug to a 4 prong plug when the colors dont match on the wires to the dryer?colors on the wires are red white black and green. colors on the terminal of the dryer are a black and yellow tied together a white in the middle and 2 blues tied together. this is a maytag atlantis dryer. thankyou chad....
