A 4-pronged dryer cord will not fit a 3-pronged outlet and will require either an adapter or a change to a dryer cord that will fit the three pronged outlet. While adapters are a simple solution, it is recommended for safety purposes that the dryer's cord itself be replaced.
The following items are needed to perform a cord change to a 3-prong cord:
- Adjustable wrench
- Magnetic nut driver
- 3-pronged dryer cord
Follow these steps to perform the change:
- Unplug the dryer and open the access panel where the cord enters the back of the dryer.
- Remove the old cord by loosening the screws that hold the old cord in place and disconnecting the ground wire or strap that connects the center terminal to the case.
- Attach the new cord by attaching the ground wire to the center terminal and the outer wires to the right and left terminals, respectively; then, attach the wire that runs from the center terminal to the dryer case.
- Replace the access panel, being sure to fit the strain relief bracket into the access hole and evenly tighten the bracket screws around the cord to avoid a short in the event that the cord is yanked.
- Plug the dryer into the outlet and give it a test run to be sure that the cord is working.
