We've all been there - a light starts flickering, an outlet stops working properly, or some other odd electrical quirk pops up that drives you crazy. Tracking down the root cause of electrical issues can be a pain, but this guide will walk you through how to troubleshoot even the most annoying and mysterious electrical problems in your home.

Check the Basics First

Before you dive into testing wires and junction boxes, check for some quick and easy fixes:

Check if the circuit breaker has tripped

Flip the breaker off and then back on again to see if that resolves the issue. Breakers trip when too much current flows through the circuit, which causes them to flip and cut power.

Replace any burnt out light bulbs

Burnt out bulbs can cause flickering or outlets to not work in that room. Swap in new bulbs to see if it fixes the problem.

Test outlets and switches

Plug a lamp into the outlet to make sure it's getting power. Switch light switches on and off to ensure they operate properly. Faulty outlets or switches cause electrical issues down the line.

Check for loose wiring

Inspect visible wires, sockets, and connections to make sure nothing has come loose, which can interrupt circuits. Tighten any loose screws or wires.

Look for tripped GFCIs

If an outlet has stopped working, check nearby outlets to see if they have GFCI protection. Hit the "reset" button on any tripped GFCI outlet, which may restore power.

Trace the Electrical Wiring Circuit

If the basics check out, you'll need to trace down where the problem lies along an electrical circuit. Here are some steps to take:

Turn off power at the main circuit breaker

Switching off all power ensures safety while you test connections. Never work on live electrical wiring!

Locate the circuit breaker controlling the problem area

Check which breaker controls the afflicted lights or outlets by flipping each one off and on to see what shuts down.

Follow the circuit wiring from the panel throughout the house

With the circuit breaker off, follow the hot wire leading out of the breaker into the wall, attic, etc. Verify all connections are intact.

Check junction boxes for issues

Junction boxes distribute power to multiple lines. Check for any loose wire connections, corrosion, or shorts.

Test sections of wiring along the way

Use a multimeter or non-contact voltage tester to confirm power flows properly through the hot wire along its path. Faulty sections will show no voltage.

Inspect individual outlets and lights

At each box, check for loose wires or degraded insulation. Problem spots will reveal themselves through your circuit tracing.

Troubleshoot Specific Electrical Problems

With a basic inspection complete, focus troubleshooting on the type of electrical issue:

Flickering lights

Dead outlets

Circuit breaker tripping

Buzzing/crackling from outlets

Lights dimming/brightening

When to Call an Electrician

Some electrical issues require a professional to handle safely:

Don't take chances with live wires! Hire a licensed electrician for major repairs.
