You turn on your trusty reading lamp and—nothing. Chances are it’s the light bulb. Remove the old bulb, screw in a new one, and you should be ready to go. If not, you’ll have to inspect further. Your problem could be …
➤ The power supply.
➤ The receptacle.
➤ The contact tab at the bottom of the light socket.
➤ The light socket.
➤ The cord or plug.
The power supply and the receptacle are easy enough to check. A voltage tester will tell you whether the receptacle is hot, and a quick trip to your fuse box or service panel will tell you whether the problem is originating there. If a breaker has tripped or a fuse has gone out, you need to discover the cause before you can consider the problem solved.
The contact tab at the bottom of the socket is the same one referred to previously in this chapter in the “Inspect First” section. Simply unplug the lamp and use a small screwdriver to pull up slightly on the tab. If the bulb still doesn’t work, you’ll have to look at your cord and plug more closely.
