What It Means
Light Will Not Turn On
Likely Causes
- GFCI or lighting breaker tripped
- Transformer not outputting 12-15VAC
- Bad relay or loose line/load wiring
- Failed LED driver or fixture
- Automation schedule or service mode disabling light
Next Checks
- Reset GFCI and confirm breaker holds
- Verify transformer primary voltage and 12-15VAC secondary output
- Check automation relay output when light circuit is commanded on
- Inspect junction box and cord connections for corrosion or water intrusion
- If voltage is present at fixture and light stays dark, fixture/driver failure is likely
