How to Change a 4-Prong Plug to a 3-Prong Plug on a GE Oven


American homes use two different plug types for 220-volt electrical outlets -- a three-prong plug and a four-prong plug. Depending on the type of plug in your home, it may be necessary to change the plug on an appliance, such as a GE oven, when you install it. This is not a difficult job, and you can accomplish it with only a screwdriver and wire strippers.

Things You'll Need

  • Four-prong oven plug
  • Screwdriver
  • Wire strippers
  • Loosen the screws holding the existing power cord on the terminal block in the back of the oven. Remove the plug and cord.

  • Strip 5/8 inch of insulation from the ends of the three wires on the new power cord. You may not need to do this, as many cords come pre-stripped.

  • Insert the bare end of the white wire under the center screw terminal and tighten the screw to hold the wire.

  • Insert the bare ends of the two other wires under the screws on either side, one to each screw terminal. Tighten the screw to hold the wire.

Tips & Warnings

  • Plugs can be purchased at appliance stores and home improvement centers.
