As a homeowner in Phoenix, it’s not uncommon to experience electrical issues—especially with the intense heat, monsoon season, and aging housing stock throughout the Valley. Identifying common electrical issues and their fixes can help you save both time and money Let’s dive into the top 10 electrical issues in Phoenix homes and how to fix them.
1. Exterior GFCIs and Circuit Breakers Tripping
Common symptoms: No power to outdoor outlets, bathroom, or kitchen outlets.
Cause: GFCIs are sensitive devices triggered by moisture, dust, or age.
Fix:
- Locate and press the reset button on the GFCI outlet.
- If that fails, reset the breaker in the main panel.
If the issue continues, the GFCI might require replacement or further inspection by a licensed electrician
2. Poor Connections in Circuitry
Common signs: Power failure after using space heaters, coffee makers, or air conditioners.
Cause: Loose wires or aged terminations inside switches, outlets, or boxes.
Fix:
Requires a licensed electrician to locate and repair the connection. DIY work is not advised for safety reasons.
3. Overloaded Circuits Causing Breaker Trips
Common signs: Power loss after using space heaters, coffee makers, or AC units.
Cause: Too many high-draw devices on one circuit.
FIX:
- Unplug devices and reset the breaker.
- If frequent, you may need a dedicated circuit installed by an electrician.
4. Outdated Electrical Panel
Common Symptoms: Rust, frequent trips, flickering lights, limited breaker space.
Cause: Panels older than 30 years can’t handle modern loads or may be unsafe.
FIX: Schedule a main panel upgrade. This is crucial for anyone doing remodels, adding casitas, EV chargers, or new appliances.
5. Loose Outlets
Common symptoms: Plugs fall out or feel wobbly.
Cause: Age or poor installation.
FIX: Replace the outlet with a securely mounted, updated unit.
6. Two-Prong Outlets
Common symptoms: Can’t plug in modern grounded devices.
Cause: Found in older homes without proper grounding.
FIX: Replace with three-prong grounded outlets or GFCI-protected units, depending on your wiring setup.
7. Buzzing, Burning Smells, or Sparking
Common Symptoms: Sounds of buzzing, burning plastic smell, or visible sparks.
Cause: Faulty wiring, damaged devices, or old outlets.
FIX: Turn off the power immediately and contact an electrician. These are serious hazards.
8. Flickering Lights
Common Symptoms: Lights dim when AC kicks on, or random flickering.
Cause: Minor surge, loose connection, or overloaded circuit
FIX:
- Install a whole-home surge protector.
- If flickering is heavy, call for an inspection—it could indicate a failing breaker or poor neutral.
9. Aluminum Wiring
Common Symptoms: Warm switch plates, intermittent power, discolored wiring.
Cause: Used in the 60s–70s, aluminum wiring expands/contracts more than copper.
FIX:
- Rewire the home with copper, or
- Pigtail connections using copper wire and approved connectors.
10. Improper DIY or Unlicensed Work
Common Symptoms: Reversed polarity, unlabeled circuits, strange wiring errors.
Cause: Unqualified or rushed work.
FIX: Only safe remedy is to hire a licensed electrician to clean it up. This is particularly crucial if you intend to sell the home.
Bonus: Beeping Smoke Detectors
Common Symptoms: Chirping every few minutes, even after changing the battery.
Cause: Low battery, sensor malfunction, or end-of-life unit.
FIX:
- Replace the battery first.
- If it continues, replace the unit—most detectors only last 7–10 years.
