What It Means
Pentair Light Will Not Turn On
Likely Causes
- GFCI/breaker tripped
- Transformer output missing
- Color Sync/automation relay not sending power
- Failed LED engine or driver
- Water intrusion in fixture
Next Checks
- Confirm breaker and GFCI hold with load disconnected
- Measure transformer secondary voltage under load
- Command light directly from relay/controller and verify output
- Inspect junction box and fixture cord for water/corrosion
- Replace fixture if proper voltage is present and light remains dark
