Dealing with strange electrical issues in your home can be incredibly frustrating. You flip a switch or plug in an appliance and it inexplicably doesn't work. Or perhaps lights flicker or you hear an unusual buzzing from your outlets. Pinpointing the root cause of these types of problems is like searching for a needle in a haystack. But with some diligent troubleshooting and basic DIY skills, you can solve that one weird electrical gremlin that's been the bane of your existence.
Conduct a Thorough Inspection
The first step is to carefully inspect your electrical system to try and identify any visible issues. I start by taking a walk through the house and testing every light switch, outlet, and appliance. If certain ones aren't functioning properly, make note of their locations. Check for the following problems:
- Loose, damaged, or missing outlet or switch cover plates - This can expose wires and create shorts.
- Scorch marks or melted plastic - Signs of overheating that require immediate attention.
- Frayed, cracked, or damaged cords - These present serious fire and shock hazards.
- GFCIs or AFCIs that won't reset - Could indicate ground faults or arc faults.
- Flickering lights - Can signal a loose connection.
I also check the electrical panel thoroughly. Look for any breakers that are flipped or fuses that have blown. This might point you to the branch circuit that's involved with the issue. While at the panel, check for signs of overheating on the wires, breakers, and bus bars which can be a major fire risk.
Troubleshoot Methodically
Once I've identified any outward issues, it's time to start methodically eliminating potential causes:
- Check connections - Open up outlets and switches and inspect wiring for loose, disconnected, or improper connections. Tighten any loose screws and reconnect or fix improper connections.
- Test with a multimeter - Use a multimeter to check voltage and current. Start at the outlet and work your way back towards the panel to isolate the problem.
- Examine extension cords and power strips - Discard any that are worn, damaged, or overloaded. Use shorter, heavier gauge rated cords.
- Inspect junction boxes - Ensure wire nut connections are tight and properly joined. Check for loose connections.
- Replace devices - Swap out suspect outlets, switches, and light fixtures. Faulty devices can cause all kinds of weird electrical issues.
- Consider an arc fault - If you can't find the source of the problem, it may be an arc fault. Have an electrician inspect and install AFCI breakers if needed.
Don't Hesitate to Call an Electrician
Sometimes, despite your best DIY efforts, that weird electrical gremlin persists. At this point it's wise to call in a licensed electrician. I know it's frustrating to defer to an expert after long attempts to fix it yourself. But electricity is dangerous when improperly handled. An experienced electrician has the proper tools and knowledge to accurately diagnose and correct the issue.
Some warning signs that require professional electrical services include:
- Repeated tripped breakers, blown fuses, or sparks
- Tingling sensations or shocks from fixtures, cords, or appliances
- Unusual burning smell from outlets or switches
- Visibly charred or damaged wiring
Though paying for an electrician is expensive, it pales in comparison to the risks of electrical fires or electrocution. Your safety is paramount. And you'll have the peace of mind knowing your wiring is secure and any bizarre electrical behaviors are finally resolved.
