Outlet Smells Like Burning: 5 Reasons Why

One thing that should not happen is an outlet that smells like burning. If you’ve noticed a singed odor near one of your outlets, it’s a sure sign that you need to pay attention. Electrical problems are the main cause of an outlet that smells like a campfire. But one thing’s for sure: No matter what causes it, this is a safety issue. Before tracking down or trying to fix the cause of the burning smell, turn off the breaker to the outlet and unplug whatever is using it. Electrical work can be dangerous and can be a serious fire risk if you don’t know what you’re doing. Unless you have electrical experience, call a local electrician to find a solution.

1. Overloaded Circuit

Outlets are designed to handle a set amount of power, so plugging in too many devices (or high-wattage devices) that draw too much power can overload the circuit. When the circuit overloads, the outlet may overheat, leading to a burning smell.

How to Fix It

Avoid overloading outlets with outlet splitters. Check the maximum output of the outlet, and move high-wattage devices to outlets rated for higher output or to a GFCI outlet, which will cut power to the outlet when an overload is detected.

2. Exposed Wiring

Exposed wiring in or behind the outlet may come into contact with metal or other materials, singeing them and emitting a smoky scent. Exposed wiring is a significant fire hazard, as it can generate sparks or come into contact with flammable material within your walls. 

How to Fix It

The fix for an exposed wire can be as simple as wrapping the wire with electrical tape or using a wire connector cap. Exposed wiring should be handled with caution, so call an electrician if you don’t have experience with electrical work. A pro will be able to complete the repair safely while minimizing fire risk.

3. Damaged Outlet Components

When your outlet has damaged components, you may smell a burning odor or notice that the outlet stops working. Damaged outlet components are especially common in older models and may be a sign that it has reached the end of its lifespan. 

How to Fix It

Fully replacing a damaged outlet is the safest and most effective way to handle the problem. Trying to troubleshoot may lead to other electrical problems, so installing a new outlet is your best bet. The cost to install an outlet is worth the peace of mind of knowing you’re protected from electrical problems and fire risks. 

4. Loose Connections

Connections can be compromised from wear and tear and the loose wiring connections in the outlet can generate heat. An improperly installed outlet may also have poor connections that degrade over time, leading to overheating and a burning smell.

How to Fix It

Tighten anything wonky using wire connector caps or reinstall the outlet altogether. As with all electrical work, this can be a dangerous DIY, so call a pro if you aren’t comfortable with this kind of electrical repair.

5. Faulty Plugged-In Device or Appliance

In some cases, the burning smell may originate from whatever is plugged rather than the outlet itself. Devices or appliances with frayed or exposed wiring, damaged plugs, or build-up of dirt or grime around the plug can be attributed to this worrisome smell.

How to Fix It

Immediately unplug anything that emits a burning odor. Inspect the wiring and plug to look for visible damage. Discontinue using the device or appliance and replace it with a new one or repair the damage before using it again.

When to Call a Pro

Never ignore a burning smell coming from your outlet—it can be a sign of a serious electrical problem and a fire risk that can put your home and safety in jeopardy. Unless you have experience troubleshooting and repairing electrical problems, call a professional electrician. Improperly performed DIY electrical work runs the risk of serious injury or even a house fire. 

A qualified electrician can answer all your questions about repairing outlets, track down the source of the burning smell, and repair the issue in compliance with codes and regulations. 

How to Prevent a Burning Outlet Smell

Ensuring your home’s electrical system is well maintained is the best way to prevent burning smells from electrical problems. If your home is older and the electrical system hasn’t been maintained, call an electrician to perform an inspection and identify any existing or potential problems. 

In addition, avoid overloading outlets with too many devices or anything that has higher wattage than the outlet can supply. Periodically inspect your outlets to ensure everything is in working order and nothing looks singed, melted, or discolored. Most importantly, address any problems as soon as you notice them—the longer you wait to fix an electrical problem, the more your home and safety are at risk.
