Expert Electrical Troubleshooting in Maine

FAQ 1 — Why does my breaker keep tripping?

Breakers trip when they detect unsafe electrical conditions — and that’s their job. Common causes include:

  • Overloaded circuits (too many devices on one circuit)

  • Short circuits or damaged wiring

  • Faulty appliances

  • Loose electrical connections

If a breaker trips repeatedly, do not ignore it. It’s a sign of an underlying issue that should be diagnosed by a licensed electrician to prevent overheating or electrical fire hazards.

Yes — buzzing or sizzling sounds almost always indicate a problem. Electrical components should operate silently.

Buzzing may be caused by:

  • Loose wiring or poor connections

  • Overloaded circuits

  • Failing outlets or breakers

  • Arcing (electrical discharge), which can lead to fire

If you hear buzzing from an outlet or electrical panel, call an electrician immediately.

Light flickering can be caused by minor issues — or more serious electrical problems. Common causes include:

  • Loose bulb or loose fixture connections

  • Failing switches or dimmers

  • Large appliances causing voltage drops

  • Loose wiring within the home

  • Issues with the electrical service feeding your house

If flickering is happening throughout multiple rooms, it’s best to have your electrical system checked to rule out unsafe wiring or service issues.

A burning smell is a major warning sign of overheating wires or failing electrical components. Common sources include:

  • Overloaded circuits

  • Failing outlets or switches

  • Loose or arcing connections

  • Damaged or aging wiring

Turn off power to the affected area if possible and call an electrician right away. Do not ignore burning odors — they often indicate a potential electrical fire hazard.

Yes. Once we identify your electrical issue, your diagnostic fee is credited toward the cost of the repair when you approve the work. This ensures you only pay once — not twice — for troubleshooting.

Large appliances (like heat pumps, dryers, or well pumps) draw a brief surge of power when they start. Small dimming is normal — but noticeable dimming can mean:

  • Loose or aging wiring

  • Overloaded circuits

  • Weak or failing breakers

  • An undersized electrical panel or service

Consistent dimming is worth having inspected, as it may indicate a developing safety issue.

A burning smell typically means a component is overheating due to:

  • Loose or damaged wiring

  • Overloaded circuits

  • Failing outlets, switches, or connections

  • Arcing inside the electrical box

Shut off power to that outlet and call an electrician as soon as possible.

GFCIs trip when they detect moisture, an imbalance in current flow, or a ground fault. Causes include:

  • Water or humidity exposure

  • Faulty appliances

  • Wiring issues

  • Overloaded circuits

If a GFCI won’t reset or trips repeatedly, there may be an underlying wiring problem that should be inspected.

This usually happens when:

  • One leg of your electrical service is loose or damaged

  • A breaker feeding multiple circuits has failed

  • There is damage at the meter or service drop

  • An external utility issue affects only one side of your service

If half the house is out, call an electrician immediately. This is often a service-level issue and can pose serious safety risks.

Dead outlets can result from:

  • A tripped breaker

  • A tripped GFCI upstream

  • Loose wires or failing outlets

  • Damaged circuits

  • Overloaded or old wiring

Try resetting nearby GFCI outlets first. If the problem continues, the outlet or wiring likely needs professional attention.

A slightly warm switch can be normal, especially with dimmers.
But a switch that feels hot, smells like burning, or shows discoloration is dangerous.

Common causes include:

  • Loose wiring

  • An overloaded circuit

  • A failing dimmer or switch

  • Incorrect wattage bulbs

A warm switch should be checked by a licensed electrician ASAP — heat inside a switch can lead to electrical failure, melting, or fire risk.

Buzzing or humming usually means something electrical is under stress.
Common reasons:

  • A loose breaker

  • A breaker that’s failing internally

  • Overloaded circuits

  • Poor connections

  • A faulty main breaker

Panels should never buzz loudly. That’s a sign of overheating or arcing.
Turn off the affected circuits (if safe) and call an electrician immediately.

This usually means the issue is localized, such as:

  • A tripped breaker

  • A loose connection on the circuit

  • A failing outlet or switch

  • A damaged wire in the wall or attic

  • A backstabbed receptacle losing contact

If resetting the breaker didn’t fix it, the problem needs a proper diagnosis to prevent overheating or further failure.

This happens when a circuit is overloaded or there’s a wiring issue.
Typical causes:

  • Too many high-demand devices on one circuit

  • Short circuits in outlets or cords

  • A failing appliance

  • A weak breaker

Repeated tripping means the circuit is at risk — it’s the breaker’s way of preventing a fire.

House-wide flickering usually points to bigger electrical issues, such as:

  • A loose service connection

  • Problems at the meter base

  • Aging wiring

  • Overloaded circuits

  • Issues with CMP’s service drop

If flickering affects multiple rooms, it’s not a simple outlet issue — it requires a licensed electrician.

A burning smell means something is overheating. The most common causes are:

  • Loose or failing wiring

  • Overloaded circuits

  • A damaged outlet or breaker

  • Heat buildup inside a panel

Turn off power to the affected area immediately and have it inspected — burning smells are always urgent.

Outdoor GFCIs often trip due to:

  • Moisture exposure

  • Weather conditions

  • Holiday lights or extension cords

  • A downstream GFCI controlling multiple outlets

  • Age or failure of the outlet

Reset the nearest GFCI — if it still won’t restore power, the wiring or device may be compromised.

New batteries don’t always fix the issue. Other causes include:

  • Detector is expired (10-year lifespan)

  • Loose wiring

  • Dust inside the detector

  • Low voltage from the circuit

  • Hardwired system needing full reset

Chirping is the detector asking for attention — and should never be ignored.

A tiny spark can be normal when plugging in devices.
But large, loud, or frequent sparks can indicate:

  • Worn outlets

  • Loose wiring

  • Short circuits

  • Failing appliances

  • Overloaded circuits

If an outlet sparks noticeably, replace it before it becomes a fire hazard.

Partial outages often mean an issue with:

  • The utility’s service line

  • A failing main breaker

  • Water intrusion at the meter/base

  • Loose service conductors

If part of your home goes dark — but not all — call an electrician. The problem is often at the service entrance and can worsen quickly.

Real Electrical Problems We See in Maine Homes

Here are actual troubleshooting issues our team has diagnosed across Southern & Midcoast Maine. If you see anything that looks even remotely like these in your home — it’s time to call a licensed electrician immediately.

Corroded Main Lugs in Electrical Panel Severe corrosion on main service lugs can lead to overheating, arcing, and total power loss. This is a critical safety hazard that needs immediate repair.
Loose & Overloaded Outlet Wiring Loose terminations cause flickering lights, warm switches, and burning odors. This is one of the most common issues we troubleshoot in older homes.
Burned & Failed Circuit Breaker Here the breaker overheated and partially melted, creating a fire risk. Breakers trip for a reason — ignoring them can lead to situations like this.\
Broken Light Switch With Exposed Wiring Faulty or worn-out switches can arc internally, causing buzzing sounds, intermittent power, and even smoke.
Overheated Hot Conductor on Breaker The hot conductor on this breaker has overheated and started to break down at the terminal. This kind of damage can cause nuisance tripping, voltage drops, and serious fire risk if not repaired.
Melted Outdoor Disconnect (Heat Pump/AC/EV Charger) Outdoor electrical disconnect boxes are exposed to weather — but they should never look like this. Overheating, loose connections, and corrosion can cause complete equipment failure.

When to Call an Electrician Immediately

Electrical issues can go from inconvenient to dangerous very quickly. Call a licensed electrician right away if you notice:

  • Burning smells, melting plastic, or discoloration around outlets, panels, or light switches

  • Repeated breaker tripping, even after resetting

  • Buzzing, sizzling, or humming sounds from your electrical panel

  • Warm or hot outlets/switches

  • Partial power loss, dimming, or lights flickering across multiple rooms

  • Smoke, scorch marks, or any sign of overheating

  • Loose, damaged, or corroded wiring or breakers

  • Water exposure near outlets, wiring, or your electrical service

  • A cable/Internet company accidentally hitting your service conductors (a very common but dangerous issue)

If something feels off, it’s always safer to have it inspected. Early diagnosis prevents electrical fires and helps protect your home and family.

Professional electrical troubleshooting in Maine ensures hidden hazards are found before they become serious problems.

Burnt Outlet — Loose Connection Hazard

A loose terminal inside this outlet created resistance, producing heat and eventually burning the device. This is a common cause of outlet discoloration, melting, and electrical fires.
If you notice burning smells, scorch marks, or warmth at an outlet, stop using it immediately and call an electrician.
