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?
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.
If you need to re-wire the outlet, these pictures will explain the anatomy of the three-prong (left) and four-prong (right) outlets. Once again, these pictures are just thumbnails--click 'em for a larger view.
Sure hope this helps you find a resolution to your delimma! Best wishes.
Hi I have a Kenmore 88042 Dryer, it came with three pronged plug which I now need to change to 4 pin plug? where do I put all these new wires like green, white, red and black?
Thanks,
How do I change a three prong plug out for the factory four prong plug?
How do I change a three prong plug for a four prong?
Hi there! Thanks for volunteering to help out! I just bought a used dryer and changed the three prong to a four prong, careful to follow the diagram and to put the white neutral loop from the dryer case on the same screw as the white neutral loop on my new plug. After the dryer ran a few minutes, sparks and smoke - quickly opened dryer to stop it and unplugged. My guess is that this is due to a loose wire from a screw that I couldn't get to tighten all the way (stripped?). Does this sound right? If so, suggestion? Thanks a bunch! Mary
