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

An electric dryer has an opening in the back, older units use a three prong cord, there will be three posts to attach cord, newer units have four prong cords, Bought separately. there will be four posts to attach, double grounded cord.

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.

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.

Picture shown is for a range cord but is exactly the same for a dryer connection.

These two pictures illustrate the power wiring on a the terminal of an electric dryer. The one on top is the old-style three-wire configuration. Most people have this type in their homes. New code changes, though, require that dryers now have a four-wire cord, shown on the bottom.
Besides the number of wires in each cord, there are two important things to notice. First, in the four-wire configuration, notice that the dryer's grounding strap is folded back on itself. The whole point of the four-wire cord is to separate the ground from the neutral. The green wire (the "new" extra wire in the four-wire cord) is attached to the dryer cabinet. In the three-wire configuration, the grounding strap is left intact and the neutral and ground are tied together.


Sure hope this helps you find a resolution to your delimma! Best wishes.

The three wire goes on the electrical block on the back of your dryer just like the cord is made. If you look at the cord, it's made flat (Most 3 wire cord are made flat, Some are not) The wire in the middle goes in the middle of the block. The two wires to the outside go to the outside of the block. It makes do difference which wire goes on which side as long as the outside wires go to the outside.

Wiring in a new power cord for your electric dryer? Upgrading your electric dryer outlet from the old three-prong to the new four-prong outlet? Well, grab hold of those two large lumps at the base of your spinal cord and let's romp through the wild and wacky world of dryer cords and outlets.

These two pictures illustrate the power wiring on a the terminal of an electric dryer. The one to the left here is the old-style three-wire configuration. Most people have this type in their homes. New code changes, though, require that dryers now have a four-wire cord, shown to the right. These are just just thumbnail pictures that you can click for a larger view. But I'll bet you already figured that out, didn't you?

Is the receptacle in the wall a four prong or three prong. You will have to match the cord on the dryer to the wall recepticle. If the wall is four prong the dryer cord has to be a four prong. The green wire with the yellow line, that is on the end of the dryer cord, is a cabinet ground and should be attached to the cabinet of the dryer and making good contact. The other three wires on the end of the dyrer cord attach to the terminal block.

use the ground on the machine.....There are 3 wires on the terminal block if you notice there is a grounding strap off the center post this will act as your ground to the machine back in your panel box the center post leads to ground anyway the other 2 are hot leads (240vac) use the 3 post you will be fine. you will be grounded let me know if you have any problems
