A malfunctioning pool light can be a simple fix or a sign of a larger, more serious electrical issue. Here at McLean Electric Co., we’ve specialized in diagnosing and repairing pool lighting problems for years, ensuring our clients’ pools are not only functional but also completely safe. While some issues are easy to spot, a recurring problem often requires the eye of a professional. Here’s a guide to help you identify the problem and know when it’s time to call us.

Common Pool Lighting Problems and What They Mean

Homeowners often try basic troubleshooting, but a recurring issue usually points to a more complex problem. We’re equipped to handle all common pool lighting issues, including:

  • Breakers Tripping Repeatedly: This is a strong indicator of a short circuit in the wiring, often caused by water intrusion or old, degraded insulation.
  • GFCI Outlets That Won’t Reset: A GFCI outlet is a critical safety device designed to trip when it detects an electrical fault. If it won’t reset, it’s detecting a persistent fault, which could be in the light fixture, the wiring, or even the circuit itself.
  • Lights That Flicker or Don’t Turn On: This can be a simple issue like a faulty bulb, but it can also be a sign of a bad transformer, loose connections, or a problem with your pool’s control system.
  • Damaged Wiring: Older wiring can become brittle or damaged over time, especially from constant exposure to pool chemicals and moisture. This creates a dangerous situation that can lead to electrical shock or fire.

When to Call a Professional Electrician

While replacing a faulty bulb is a straightforward task for a homeowner, most other pool lighting problems require a professional. You should contact us if:

  • The breaker for your pool lights keeps tripping.
  • The GFCI outlet won’t reset.
  • The lights are flickering, even after you’ve tried to replace the bulb.
  • You notice any signs of physical damage to the wiring or light fixture.

Our licensed electricians can diagnose the problem and safely perform the necessary repairs, ensuring the work is compliant with all safety codes.
