Common Electrical Issues and How to Troubleshoot Them
1. Frequently Tripping Circuit Breakers
Repeated breaker trips are one of the most common issues Chicago electricians handle in 2026. Overloaded circuits, short circuits, or faulty breakers can disrupt your home or business.
Causes:

Troubleshooting Steps:
- Turn off the breaker fully, then switch it back on.
- Unplug all devices from the affected circuit.
- Reconnect appliances one by one to identify the cause.
- If the breaker trips immediately, call a licensed electrician, as this may indicate a short circuit or wiring problem.
2. Flickering or Dimming Lights
Flickering lights are a common problem in older Chicago homes and commercial buildings. This issue may indicate loose wiring, voltage fluctuations, or panel problems.
Troubleshooting Steps:
- Check and replace bulbs if necessary.
- Tighten fixtures and connections.
- Observe whether flickering occurs when large appliances or HVAC units start.

Outlets that stop working or GFCIs that won’t reset are common in Chicago, especially in older buildings with aging wiring.
Causes:

Troubleshooting Steps:
- Press the “Reset” button on the GFCI outlet.
