How To Replace A Touch Lamp Control Box

Posted on: 13 October 2016

If your touch sensitive lamp doesn't work, don't throw it away. It is possible to fix it by replacing the control box inside the lamp body that controls the touch sensitivity.

Constant usage and power surges can damage the lamp wires causing it to stay on or off. You should be able to replace the control box yourself. Here are tips to replace a touch-sensitive lamp control box.

Prepare to Work

For this project, you need:

  • work gloves
  • electrical tape
  • flat-head screwdriver
  • pliers
  • wire strippers
  • wire nuts
  • replacement control box

Unplug the light, and let it cool, if has been in the "ON" position. Access the lamp harp by removing the lamp shade. Press the lamp harp sides to free it from the lamp.

Remove the Old Control Box

Set the lamp on a flat work surface. Detach the bottom of the lamp by removing the screws with the flat-blade screwdriver. Some lamps may have a plastic lid on the bottom instead of fasteners.

The control box is attached by four wires. The wires will be red, yellow or gray, black, and white. The black wire attaches to the plug wire that feeds into the lamp base, and the red or gray wire connects to the socket.

Touch lamp wiring differs from standard house wiring, since the wires are designed to match the lamp color. Feel the wiring to be certain. Hot wires are smooth to touch, and neutral wires commonly have ridges.

Label the hot wire that attaches to the black wire with tape. Wrap electrical tape around the other hot wire that connects to the yellow, gray, or red wire.

Untwist the wire nuts. Use the pliers to rotate the nut clockwise on the nipple (hollow pipe) attached to the yellow or gray wire. Remove the nipple, and gently pull the old box from the wiring.

Attach the New Control Box

Strip one-fourth inch of insulation from the lamp wires. Reinsert the nipple to the yellow wire on the new control box. Tighten the nut with the pliers.

Connect the white wire to the wires on the lamp without tape, and secure the connection with a wire nut. Connect the black wire on the new control box to the plug wires with tape on the lamp, and attach a wire nut. Connect the red and yellow or gray wires to the other wire with tape, and secure the wires with a wire nut.

Remove the tape, and reinstall the lamp harp and base. Test the lamp. If the lamp still doesn't work, or you don't trust your skill, contact an electrician from a company like Conway Electric.
