Testing a Lamp Light Socket
|
|
Summary: The bulb isn’t working!! It hasn’t burned out and also the power supply in the house is proper. So where does the problem lie? Is it the plug or the socket which is faulty?
You would need a continuity tester to establish the area of the problem. First of all the socket should be removed from the frame of the lamp and the lamp should be unplugged followed by removing of the shade the harp and the bulb. Then the outer covering of the socket should be squeezed towards the base and insulated sleeve needs to be slipped off.
Attach the wire of the tester to one point of the plug and the probe to the sockets silver screw and brass screw one by one. Now repeat the process by attaching the wire to the second point of the plug. The tester’s light should turn on any one of these. If it doesn’t, it’s the wire that is at fault and needs to be replaced.
For testing the socket, attach the wire of the tester to threaded collar and the probe to the brass screw. Switch the lamp off and on a few times. Accordingly the tester light should also blink. If it doesn’t, it’s the socket that needs to be replaced.
The continuity tester is a very important and helpful tool to determine the connectivity of an electrical circuit and is easily available at any hardware store for less than ten dollars. It is powered with battery and resembles a flashlight with two probes. You can find complete information on the package enclosed with it.
