Step 1: Put safety first

Electricity is unforgiving. Even a basic outlet can deliver a dangerous shock if handled the wrong way. Before you start, set a clear rule: safety or stop.

Follow these basics:

1. Turn off power to the problem circuit at the breaker before touching wiring or devices.
2. Use a non‑contact voltage tester to confirm power is off.
3. Stand on a dry surface, keep hands dry, and remove metal jewelry.
4. Never open the main service panel cover beyond the breaker door. The service lugs remain live.
5. If you see scorch marks, a burning smell, buzzing at the panel, or heat on a breaker, stop and call a licensed electrician.

Two fast facts for peace of mind:

• Brothers Plumbing, Heating, and Electric holds an A+ rating with the Better Business Bureau and is a two‑time BBB Torch Award winner for ethics.
• We email you a photo of your technician before arrival and make a satisfaction call after the job.

Step 2: Identify the circuit and the symptoms

Good troubleshooting starts with a good question: what exactly is failing, and where? Map what works versus what does not.

• Write down the exact symptom: no power, intermittent power, flicker, tripping breaker, or warm device.
• Note the location: one outlet, one room, or multiple rooms. If multiple rooms, check if they are on the same floor or share a wall.
• Ask what changed recently: new appliance, storm, holiday lights, or DIY work.
• In Denver’s older bungalows and brick homes, mixed wiring and additions can put too many devices on one circuit. Seasonal storms along the Front Range can also trigger nuisance trips and surges.

Quick logic helps:

• Single outlet dead while others work: likely a loose backstab or worn receptacle.
• Several outlets dead in kitchens, baths, garages, or outdoors: likely a tripped GFCI upstream.
• Lights dimming when a large appliance runs: possible overloaded circuit or weak connection.
• Repeated breaker trips with no obvious load: possible short or failing breaker needing replacement.

“Great job Brothers! … Nick was on time, upfront about the charges and scope of work and was able to diagnose the wiring quickly.”

Step 3: Check breakers, fuses, and GFCIs

Most power losses are solved here. Do a methodical pass.

1. Open the panel door and look for any breaker handle not fully aligned with the others. A tripped breaker is usually halfway between ON and OFF.
2. Reset properly: push firmly to OFF, then to ON. If it will not reset or trips again immediately, stop. You likely have a short or equipment fault.
3. Test GFCIs: Kitchens, bathrooms, garages, basements, and outdoors often have a GFCI that protects downstream outlets. Press RESET. If it will not hold, unplug all loads on that circuit and try again.
4. Check AFCI breakers if present. These protect against dangerous arcing from damaged cords or staples. Press the TEST button, then reset.

Know your limits:

• Warm, humming, or scorched breakers need a professional.
• Federal Pacific Electric Stab‑Lok style equipment is widely considered unsafe by today’s standards. If you still have one, replacement is the smart move for safety and insurance compliance.

“My breaker box issue was quickly diagnosed and they fixed it quickly.”

Step 4: Test outlets and switches methodically

Now move from the panel to the problem area. Work from upstream to downstream.

Tools that help:

• Non‑contact voltage tester to confirm live versus dead.
• Plug‑in receptacle tester to spot open grounds, reversed polarity, or tripped GFCIs.
• A simple lamp or phone charger as a known‑good load.

Steps:

1. Verify the breaker is ON and GFCIs are reset.
2. Test each outlet in the affected area. If the first outlet downstream is dead, open that device box only after the breaker is OFF.
3. If you find backstabbed wires, move them to the screw terminals for a firmer connection. Backstabs loosen over time.
4. Wiggle‑test gently. If flicker occurs when you touch the device, you likely found a failing connection.
5. For switches, remove the cover plate and look for heat discoloration or cracking when the breaker is OFF. Replace worn switches.

Denver tip: Many older houses in Wash Park, Baker, and Congress Park have shallow boxes. Do not cram devices; pigtail and fold conductors neatly to avoid loose connections.

“Matthew was fantastic! … he was able to diagnose the issue & get it repaired in no time!”

Step 5: Inspect fixtures, cords, and loads

Sometimes the circuit is fine and the appliance or fixture is the culprit.

Run this checklist:

1. Try a different lamp, vacuum, or phone charger on the same outlet. If it works, the original device is faulty.
2. For ceiling lights and fans, check the bulbs and the mounting hardware. Loose fan brackets can cause intermittent connections.
3. Space heaters, portable AC units, and older refrigerators can trip breakers due to high startup current. They often need a dedicated circuit.
4. Extension cords and power strips cause voltage drop and heat. Plug critical devices directly into a grounded outlet.
5. Outdoor receptacles and fixtures in Colorado winters can trap moisture. Look for GFCI trips after snow or irrigation.

If a specific device trips the breaker every time, keep it unplugged and schedule service. If multiple devices cause trips, you might be at the circuit’s capacity and need a new dedicated run.

“Great service. Joe R was friendly and knowledgeable… He diagnosed the problem and was able to fix it within an hour.”

Step 6: Isolate wiring faults without opening walls

You can narrow down a wiring or connection issue before any invasive work.

Do this in order:

1. Turn off the breaker. Remove the suspect outlet or switch and inspect wire nuts, pigtails, and insulation.
2. Look for loose neutrals. A loose neutral can cause dimming, flicker, and device failure without tripping the breaker.
3. Check for aluminum branch wiring in some 1960s–1970s homes. These need special connectors and techniques to be safe. If you see “AL” on the jacket, stop and call a licensed electrician.
4. Identify multi‑wire branch circuits that share a neutral. They require handle‑tied breakers. If you do not see a handle tie, this is a code and safety issue.
5. If a junction box is hidden behind drywall or cabinets, do not guess. Hidden splices violate code and create hazards. A professional can locate them with tracing tools.

Front Range reality: Lightning during summer monsoons and fast temperature swings cause surges and expansions that loosen connections. Whole‑home surge protection and periodic inspections reduce risk.

“Spencer came out, diagnosed the problem and had it fixed in under an hour.”

Step 7: Decide repair versus call a licensed electrician

DIY has limits. Call a pro when you encounter any of the following:

• Repeated breaker trips after a proper reset.
• Buzzing breakers, burning odors, hot devices, or scorch marks.
• Water exposure in a panel, meter, or device box.
• Aluminum wiring, old fuse panels, or Stab‑Lok equipment.
• New circuits for EV chargers, spas, HVAC, or kitchen remodels.
• Permits or inspections needed for insurance or real estate.

Frequently Asked Questions

What should I check first if an outlet stops working?

Start at the breaker and GFCI. Reset the breaker fully OFF then ON. Press RESET on nearby GFCIs in kitchens, baths, garages, basements, and outdoors. If it will not hold, unplug loads and try again.

Why does my breaker trip when the microwave or space heater runs?

High‑draw devices can overload general‑purpose circuits. The fix is a dedicated circuit or reducing simultaneous loads. If it trips immediately, you may have a short or a failing breaker and should call a pro.

Are flickering lights dangerous?

Occasional flicker can be normal with large appliances starting. Persistent flicker, dimming, or buzzing indicates loose connections or overloaded circuits. This can be a fire risk. Schedule a professional inspection.

Do I need an electrician for a new EV charger or hot tub?

Yes. These require dedicated circuits, load calculations, and permits. A licensed electrician will size the circuit, install GFCI protection as required, and ensure code compliance.

How often should I get an electrical inspection?

At least every 3 to 5 years for most homes, or annually through a maintenance program. Older homes, recent renovations, or frequent trips warrant more frequent checks.
