Possible Causes

Failed LED light assembly, Loose low-voltage connector, Water intrusion into light housing, Faulty LED driver on control board

How to Fix / Troubleshooting

Safety first: Turn off power at the GFCI breaker before working on lighting circuits.

Lighting issues are usually low-voltage but still require caution.

  • Check control settings: Ensure lights are turned on via the topside panel and not in a dimmed or off mode.
  • Inspect connections: In the equipment bay, locate the LED light harness connectors and ensure they are fully seated.
  • Identify failed light: If multiple lights are daisy-chained, a single failed light can affect others. Look for any light that is dim, discolored, or full of water.
  • Replace faulty light assembly: Drain water below the light, remove the retaining ring, pull the light housing, and install a compatible American Whirlpool LED light assembly.

If all lights are out and no voltage is present at the light harness, the LED driver or control board may need replacement.
