Why Electrical Troubleshooting Matters

Common Electrical Problems & How to Troubleshoot Them

1. Flickering or Dimming Lights

Possible Causes:

• Loose bulb or connection
• Overloaded circuit
• Faulty light fixture
• Voltage fluctuations

Troubleshooting Tips:

• Make sure that if the light is on a dimmer, the LED bulbs are rated for dimming.
• Make sure bulbs are screwed in securely.
• Try replacing the bulb.
• Check if multiple lights flicker when a large appliance starts, this may indicate a circuit overload.
• If flickering continues, call a licensed electrician for a wiring inspection.
  

2. Frequently Tripping Breakers

Possible Causes:

• Too many devices on one circuit
• Faulty breaker
• Faulty wiring
• Short circuit or ground fault

Troubleshooting Tips:

• Unplug some appliances and reset the breaker.
• Avoid using power strips for large electrical loads.
• If the breaker trips again immediately, you may have a short or faulty breaker—this needs professional attention.
  

3. Dead Outlets or Switches

Possible Causes:

• GFCI tripped (common in kitchens, bathrooms, garages)
• Loose wiring
• Failed outlet
• Breaker issue



Troubleshooting Tips:

•  Look for nearby GFCI outlets and press the  RESET  button.
• Test the outlet with a lamp or phone charger.
• If multiple outlets go out at once, the issue may be within the circuit wiring.

4. Burning Smells or Hot Outlets

Possible Causes:

• Overloaded circuits
• Loose connections
• Faulty appliances
• Damaged wiring

Troubleshooting Tips:

• Turn off power immediately  to the affected outlet or circuit.
• Stop using the appliance plugged into the outlet.

5. Buzzing Sounds or Humming Noises
