Eventually, you may run into a problem with your touch lamp. If it’s not turning on, it could be an electric problem, a damaged cord, a burnt out bulb or a worn out sensor.
Separate the touch sensor from the wires by twisting their wire connectors. You may need to use a pair of pliers to disconnect the wire that is physically attached to the lamp. Reach the pliers down to the nipple of the lamp, a small metal tube threading wires through it. Here, you can remove the wire attached to the sensor.
Locate the sensor, which is a small plastic square with four wires attached to it. The colors vary depending on who manufactured the sensor, but the parts are typically black, white, red and yellow. These wires are connected to important pieces of the lamp and are essential for it to function correctly.
One warning: Electrical shock is a possibility with this project. Make sure all electronics are unplugged and away from water at all times.
Unplug the touch lamp, and pry off the bottom with a butter knife. Check that all the wire connections are inside the lamp. If necessary, cut and rewire with wire nuts.
It is possible to purchase an apparatus that will convert a traditional lamp to a touch lamp. Typically, you can find these at home improvement stores. Follow manufacturer installation instructions for best results.
How to Repair a Touch Lamp. A touch lamp utilizes a sensor that lets you turn the lamp on or off with the touch of your hand. It can be more difficult to repair a touch lamp because you must disassemble it befor replacing any parts. You can do it by following these steps.
Three of the four wires are connected to other wires within the lamp and the fourth physically attaches to the lamp. Take a photo of the lamp’s connections so you know how to rewire it when you insert your replacement sensor.
Replace your old sensor with a new, working one and reconnect the wires as they were before. Use the photo you took as a reference of how the wires should be attached. Make sure to tighten the nut on the nipple of the lamp when you’re done replacing the sensor wires.
Touch lamps make turning the lights on and off a luxurious convenience. Replacing old lamps with touch lamps mean less fumbling for switches and more time relaxing.
Check any fuses inside the lamp. Some newer touch lamps have soldered-on fuses. Replace any burnt fuses with fuses that carry the same rating.
Replace the touch sensor located at the base of the lamp. Purchase one at any electrical supply store or home improvement outlet, and follow the manufacturer’s installation instructions. Installation mostly involves nothing more complicated than following the color-coded wiring.
Replace the control box with the new one you have purchased. Connect the wires in the same way they were before. You can use an orange wire nut to twist the wires together so that they will fit more neatly into the box. Replace the control box and its cover. Put a light bulb in the lamp and plug it back in. Finally, touch the lamp to turn it on and be sure it is working.
Over time, the touch sensors in a three-way touch lamp may fail. Usually, you can find a control box containing the dimmer switch at the base of the lamp. These are available for purchase and replacement, but it’s advisable to photograph the way its wires are connected to the lamp before you disconnect it. This way, when you purchase a new control box, you will be able to reattach the wires in the same manner that they were connected before. These boxes are sold at home improvement and hardware stores.
Troubleshoot the problem. Make sure it’s not as simple as a bad bulb or a faulty electrical outlet. If the wall switch controls the outlet, make sure the switch is on.
Access the electronics in your lamp by removing its bottom casing. This process is different for every lamp, but usually involves twisting the base of the lamp. Make sure you can replace the bottom easily after your project.
Install a new power control transistor, called a thyristor or TRIAC. You’ll find this on the circuit board in the base of the lamp. The power control transistor is the largest component on the board. Remove, place the new one in the board and solder into place.
Three-way touch lamps are a fun and convenient alternative to traditional switch lamps. Sometimes, the mechanism within touch lamps stops working. Because these lamps usually include a dimmer control switch, the easiest way to fix them is to troubleshoot that piece. It is also possible to use an external dimmer switch.
Touch lamp sensors do wear out after a period of use. You can replace the sensor yourself rather than purchasing a new touch lamp. This option is eco-friendly and a great way to save money. Your local hardware store will have the replacement parts you need.
You’re finished! It’s time to replace the bottom of your lamp and test the light to see if your project was successful.
Touch lamps work because the human body functions as a link in the circuit. The body is warmer than the air, has resistance and has radio reception. As such, it’s possible to control the brightness of a lamp just by touching it.
Additionally, touch-sensitive lamps rely on the body’s capacitance, which means its ability hold electrons. When you touch a lamp controlled this way, you are allowing the circuit more electrons.
Unplug the lamp, remove the light bulb and carefully turn the lamp on its side to gain access to the base. Remove any panel housing, the control box and dimmer switch. This may require the use of a screwdriver. Next, photograph the wire arrangement and remove the dimmer switch.
Purchase a replacement sensor or kit from the store. Clear a workspace and unplug your lamp to begin.
There are workarounds to repairing a lamp in the above manner. You can also use dimmer sockets that screw into the lamp’s light bulb socket. Once you have screwed in the socket, you can add a light bulb. In addition, there are dimmer sockets that plug into the wall. Once you plug your lamp into these sockets, it will operate like a touch lamp.
