Porcelain Table Lamp Repair - New Socket and Cord

A customer brought in this table lamp the other day and said it needed a new socket and cord set. This is a common repair for any lamp. If you found a lamp at a yard sale, flea market, or online and it needed some basic repair, these are the steps to take.

First, always give the lamp a general inspection. This will help you prepare a list of needed parts. We like to only replace bad, worn out parts. Safety is also an issue. Loose hardware and non-polarized plugs should be addressed as part of any repair.



This lamp seems to be in decent shape so the only lamp parts needed for this repair are:

1) Brass lamp socket

40250 - On-Off Leviton Light Socket, Brass, Polished & Lacquered


2) Lamp cord set 

Antique Brass Color, 18/2 Plastic Covered Lamp Cord

The repair starts by unplugging the lamp and removing the light bulb.


Next, remove the harp from the lamp. Lift the locking couplings and squeeze the harp toward the socket.


Remove the socket shell from the socket cap. Using a flat head screw driver, apply pressure on the socket shell and lift it from the socket cap.




Unscrew the old lamp cord from the old socket interior and remove the socket interior.



Untie the old UL Knot and pull the old cord down to the lamp base.



Now you want to remove the old socket cap. Loosen any set screw and unscrew the socket cap from the lamp body. Screw the new socket cap on the threaded rod and tighten any set screw. If your lamp has a front and back, make sure your harp saddle is oriented side to side.






With the socket and cord removed, now is the best time to tighten the lamp body. The lamp will go back together the same way it came apart. First, push the new lamp cord up the lamp body to the socket cap.



Next, tie a UL Knot in the lamp cord.


Screw the wires onto the new socket interior. The smooth wire connects to the brass screw and the ribbed wire connects to the nickel screw.


Slip the socket shell over the interior. Pull any cord slack back down the bottom of the lamp body. Snap the socket shell into the socket cap making sure both sides are securely snapped into the cap.


Add a bulb and test the lamp.



This lamp is back in service for another 40 years. Total cost: < $25.00 total time < 45 minutes
