An outlet acting up? A cheap plug-in tester tells you what's going on without ever touching a wire. Here's how to use one and read what it's telling you.
The safe way for a homeowner to check an outlet is with a plug-in tester, a little three-light device that costs about ten dollars at any hardware store. It tells you a lot without ever removing a cover plate or touching a wire, which is exactly where a homeowner should stop.
Those three cover a surprising number of "dead" outlets with no tools at all.
What a tester is, and isn't: it safely tells you whether there's a problem and roughly what kind. It does not fix anything, and diagnosing or correcting a wiring fault means working inside the box — which is a licensed electrician's job. The value of the tester is knowing when to make that call.
The tester shows any fault (open ground, reversed wiring, open neutral), or if an outlet is warm, discolored, buzzing, sparking, or has scorch marks, or if plugs fall out loosely. Do not open the outlet or try to rewire it yourself. Reversed or ungrounded wiring and loose connections are real shock and fire hazards that belong to a pro.
Plugging in a tester and reading the lights is a safe homeowner task. Anything the tester reveals — a wiring fault, a missing ground, a dead circuit you can't restore with a reset — is where a licensed electrician takes over. In Indiana, electrical work is licensed trade work, and for good reason. Knowing that line is the whole point of the tester.
That's inside-the-box work and a real hazard. Let us get a licensed electrician on it — don't open it up yourself.

It is not professional advice and is not a substitute for a licensed electrician. Do not open your electrical panel, replace wiring, or work on any circuit you are not certain is safe.
