How to Fix Touch Lamps
Help is here to shed some light on performing general lamp repairs and problem diagnosis with regard to dimmers and touch lamps. Several options are available for you (or a qualified service person) to restore functionality to your lamp, ranging from simple adjustments to the core components (socket, plug, wiring and switching mechanism) to providing a complete restoration of the electrical components.
1. Confirm that the light bulb is functional. Perform this test in another lamp that you know is functioning properly. If the bulb is not working, try a new one, but bear in mind that many lamps have wattage limitations. This is most evident in touch-type and dimming-type lamps where there are maximum wattage's for those devices. Also, compact fluorescent lamps, or CFLs, and light-emitting diodes, or LEDs, typically will not function in these situations unless specifically designed for it.
2. Move on to the actual diagnosis, starting with an external visible inspection.
3. Unplug the lamp; then check the interior of the socket, making sure the threaded shell is securely riveted to the bottom of the socket housing and that the "tongue," the small metal protrusion that contacts the bottom of the bulb, is raised approximately 1/4 inch. A pencil eraser does a good job of raising this. If the socket is in good repair, proceed to step 4; if not the socket must be replaced.
4. Examine the plug and the wire for the lamp. Carefully check to see if the wires are in good condition (no breaks, frays or burn marks) and that they are securely fastened to the plug. If there is any indication that it is burnt or damaged, then the wiring and/or plug will have to be replaced. If all is in good repair, then proceed.
5. Consider your options when repairing a touch lamp (or lamp with a mechanical dimmer).
Option 1 is to bypass the touch device by removing or at least disconnecting the device and wiring directly to the socket. Adding a line switch or in-wall touch sensor will restore functionality.
Option 2 is to replace the sensor (or dimmer). If possible, try contacting the manufacturer of the lamp and inquire if replacement components are available (Since about 99.9% of these type lamps are imports from Asia, few, if any parts are available).
TIPS - A handful of companies offer generic replacement solutions, such as Westek and Amertac, which provide direct wire, screw-in socket adapters and plug-in wall adapters that are easily sourced on the Internet or your local electrical supply house, lighting showroom or electronics store. Remember, you must disconnect the internal touch sensor to utilize an after-market product. As with any repair or installation related to electricity, if you are not confident with your skills in electrical repairs and rewiring, bring your lamp to a trained lighting professional.
