Having an outlet that doesn't seem to work properly can be frustrating. However, this is usually an easy fix if you know what to look for. Here's a comprehensive guide on troubleshooting and repairing a quirky outlet.

Symptoms of a Faulty Outlet

Let's start by going over some of the common symptoms of an outlet that needs attention:

Loose Plugs

Plugs don't stay firmly in the outlet or fall out easily. This indicates the outlet is loose.

No Power

The outlet provides no electricity at all to devices. This could mean a loss of power to the outlet.

Intermittent Power

Devices randomly lose power or turn off even when plugged in. This points to a wiring problem.

Buzzing/Cracking Sounds

You hear strange buzzing, cracking or sizzling noises from the outlet. This suggests an electrical short.


Sparks or small shocks coming from the outlet when you plug in a device. A major safety hazard.

Burning Smell

A burning odor coming from the outlet area likely means overheated wires.

If you notice any of these issues, it's time to take a look behind the outlet.

Checking the Outlet

Before doing any work, make sure the circuit breaker for the outlet is switched off. Test that the power is off by plugging in a lamp and making sure it doesn't turn on.

Then, remove the outlet cover and unscrew the outlet from the electrical box. Gently pull the outlet out to inspect the wiring.

Look for:

Any of these would cause the outlet to malfunction.

Faulty GFCI Outlets

For outlets with GFCI protection (often in kitchens, bathrooms and outdoors), also make sure the GFCI hasn't simply tripped.

Press the "Reset" button on the outlet to see if power returns. If it doesn't, the GFCI is probably defective and needs replacing.

Fixing Wiring Issues

If you found a wiring problem behind the outlet, the following fixes may apply:

Loose Wires

Damaged Wires

For cracked or melted insulation:

Corroded Wires

Be sure to wrap any repaired spot with electrical tape.

Replacing the Outlet

If the outlet itself is damaged or faulty, replacement is the best option.

When buying a new outlet, match the voltage (120V), number of receptacles, and form factor of the old one.


Finally, turn circuit breaker back on and test that the outlet now works correctly using a lamp or phone charger.

When to Call an Electrician

While many outlet issues are DIY-friendly, it's best to call a licensed electrician if:
