Flickering lights are one of the most common electrical complaints from Florida homeowners. Sometimes it is harmless. Sometimes it is a warning sign of a serious problem.
Here are the most common causes of flickering lights — and when you should call a licensed electrician.
1. A Single Bulb Is Loose
If only one light flickers, the bulb may simply be loose. Turn off the power, tighten the bulb, and see if the problem resolves. If it does not, the socket may need replacement.
2. Voltage Fluctuations
If lights flicker when you turn on a large appliance like an AC unit or dryer, your panel may be struggling to handle the load. This is common in older homes with 100-amp service.
3. Loose or Damaged Wiring
Loose connections in your wiring, outlets, or panel can cause flickering. This is a fire hazard and should be addressed by a licensed electrician immediately.
4. An Overloaded Circuit
If too many devices are on one circuit, the breaker may struggle to keep up. The solution may be redistributing loads or adding a dedicated circuit.
5. An Aging Electrical Panel
Older panels — especially Federal Pacific and Zinsco — can develop loose connections and corroded bus bars that cause flickering. If your panel is over 25 years old, it needs evaluation.
6. Utility Company Issues
Sometimes the problem is outside your home. If your neighbors are also experiencing flickering, contact your utility company.
