Simple Cord Replacement on Table Lamp

Older table lamps have outdated and nonpolarized plugs. New lamp cords are safer, polarized and have better insulation than their decades old predecessors. There are also many more colors on the market today to match the color and style of the lamp.

This old lamp has an ugly white cord set on an antique brass color body and socket. A new cord set will make this lamp look better and be safer for the user.


For this lamp repair we need three lamp parts: an antique brass color lamp cord set, a socket cap insulator and a turn knob paper insulator . We are going to break it down into 5 steps.

40326 - Paper Insulator for Turn-Knob Electrolier Socket

Step 1: Inspect Lamp

Always inspect the lamp before you get ready for repair. There may be other parts that are worn out and need to be replaced. If the lamp is working, test the socket with a good bulb. Make sure the switch feels and sounds as it should. Inspect the harp, harp saddle and finial. Doing the repair 1 time will save you time and frustration. 

Our inspection on this lamp revealed an outdated plug and worn socket insulators. 


Step 2: Remove the Socket

If the harp is still attached, remove the harp by lifting the locking couplings and squeezing the harp toward the socket. Lift the harp out of the harp saddle. 




With the lamp unplugged, you can open the socket shell from the socket cap. The socket on this lamp has a snap in socket. There are two spots marked "Press" on the socket shell. With a flat head screw driver, you can apply pressure to these points and release the socket shell from the cap.



Step 3: Remove the Socket Interior

With the socket interior completely exposed, you can unwire the interior by unscrewing the socket terminals and removing the lamp cord. 




Step 4: Remove the Old Lamp Cord

Untie any UL Knot in the cord so you are able to pull the cord from the base of the lamp. For this lamp the base has a wire way hole. To access the cord from the center of the base we peeled back the bottom felt cover and pulled the cord through the lamp body. 




Step 5: Replace the Lamp Cord and Rewire the Lamp

With the old lamp cord out of the lamp you are ready to rewire the lamp. If the lamp spins or seems loose in any way, now is the right time to tighten the lamp body by tightening the nut on the bottom of the base to the socket cap. 











The new lamp cord uses the same path as the old lamp cord and goes up to the socket cap. Make sure you tie a UL Knot in the lamp cord. The smooth lamp cord connects to the brass screw and the ribbed cord connects to the nickel plated screw terminal on the socket interior. Pull any cord slack back through the base of the lamp, then out the wire way.

Pull out the old socket and cap insulators and replace them with the new ones. The socket interior should rest on the socket cap before the socket shell is snapped in place. Make sure you orient the socket switch center of the harp saddle and snap the socket shell into the socket cap. The harp goes back in the saddle by squeezing the posts and locking the tabs. Using a good bulb, test the lamp.
