How to Troubleshoot Electrical Outlet Problems in One Room

Author: Passey Electric. |


Electrical outlets are an essential part of our day-to-day life, giving us the power to run our devices and appliances. But, it can be challenging to identify the problem when they malfunction. 

Troubleshooting electrical outlet problems in one room can be daunting, but it doesn't have to be. This article will discuss how to identify and troubleshoot the issue before you call in the professionals.

What Causes Faulty Electrical Outlets 

1. Loose Wiring

Wires can become loose from various sources, including wear and tear, rodents, or a poor installation job. Loose wiring can cause multiple issues, including sparking and electrical shocks. 

Inspecting the wiring regularly and replacing loose connections is essential to prevent these issues.

2. Faulty Circuit Breaker

Circuit breakers control the flow of electricity to the various appliances and devices in the building. If the circuit breaker is broken or damaged, it can cause the electrical outlet to malfunction. 

3. Insufficient Electric Supply

A lack of power can also cause a faulty electrical outlet. If the power supply to the outlet is insufficient, it can cause the outlet to malfunction. 

How to Troubleshoot Faulty Electrical Outlets 

1. Check the Electrical Panel

You should first check your home's electrical panel or circuit breaker. It helps to identify if the power is cut off to the house or only in the specific room you're working with.

If it has been tripped, flick the switch back in position, and if the outlet is still not producing power, then the underlying issue may be with the outlet itself. 

It's important to note that if the breaker trips again soon after resetting it, you should refrain from resetting it again and reach out to an experienced electrician as quickly as possible.

2. Use a Voltage Tester

First, unplug any connected appliance before you check the outlet to reduce the risk of electric shock.

Once the device has been removed, use a voltage tester to check if the outlet produces an electrical charge. If it shows that the power is on, you can try connecting a device to the outlet to see if it works. 

If there is no charge when you check the voltage or if the outlet still doesn't work after connecting a device, the issue is most likely the outlet itself or its wiring. If this is the case, it's best to consult an experienced electrician to resolve the problem safely.

3. Replace the Power Outlet

First, you'll need to turn off the power source to the outlet at the circuit breaker box before beginning. Then, use a voltage tester to check if the power has been completely cut off. 

When you are sure the power has been switched off, remove the cover plate and unscrew the old outlet. Next, remove the wiring from the existing outlet and connect it to the new outlet. 

Make sure each wire is connected to the appropriate terminal to ensure the outlet will work properly. Once the connections are secure, place the outlet into the wall and screw it in. Finally, attach the cover plate, turn on the power, and test to see if the new outlet is functional.

4. Test the Outlet

After replacing the outlet, it's important to test it to ensure it's connected and working correctly. 
You should use a voltage tester to check if the power runs to the outlet. 

When you have confirmed an electrical charge, you can connect a device (like a lamp or a phone charger) to the outlet to see if it powers up. 

If there is no electrical charge or the device does not power up after being connected to the outlet, this may indicate a connection issue. In such a scenario, it's best to consult a licensed electrician to investigate the problem further. 


Fixing a faulty electrical outlet is essential to avoid the potential dangers of electrocution or fire. Ensure that safety precautions are taken, such as turning off the power to the outlet, using appropriate tools for the job, and using safety equipment. 

However, it's still best to consult a professional electrician to diagnose the issue and determine the best action.
