How to Install a 3 Prong Cord on an Electric Range

When you move into a new place, you may find that some outlets will not work with your appliances.
Houses built before 1996 have three-prong outlets for the dryer and the electric range. Due to new electrical safety requirements, new homes and appliances must have four-prong outlets and cords. You can change the four-prong cord on your electric range to a three-prong cord. You can purchase three-prong appliance power cords from hardware stores and appliance stores.

Step 1

Remove the access panel to the power connection on the rear of the range with a Phillips-head screwdriver. The access panel will be beside the power cord. Some model ranges have an extruding cover box over the top of the access panel area. If your model has this box, remove the four hex head screws with a nut driver and then remove the access box.

Step 2

Remove the terminal screws securing the power cord wires to the terminal block with a Phillips-head screwdriver. Remove one screw at a time, pull the wire off the screw and reinsert the screw in the terminal block. (This will ensure you don't lose the terminal screws.)

Step 3

Loosen the holding clamp below the access area that secures the power cord to the range with the Phillips-head screwdriver. You do not need to take this apart; just loosen the clamp enough to pull the cord out of the range. Remove the power cord from the range.

Step 4

Insert the end of the three-prong power cord through the holding clamp until the three wire leads are at the terminal block. Connect the red wire to the terminal screw on the right and the black wire to the terminal screw on the left. Tighten both terminal screws with a screwdriver to secure the wires.

Step 5

Connect a copper grounding strip between the middle terminal screw and the green screw on the range frame. Some manufacturers attach a grounding strip to the frame in the event a three-prong cord is necessary.

Step 6

Place the white wire on the middle terminal and tighten the terminal screw with a screwdriver to secure the grounding strip and the white wire. Secure the grounding strip to the frame by tightening the screw.

Step 7

Secure the power cord to the range by tightening the holding clamp. Reattach the access panel to the back of the range with the retaining screws.
