Spa lights do not work or only some LEDs function; other spa functions are normal.

Safety: Turn off power before accessing light wiring or the control pack.

• Check light settings: Ensure the light function is turned on from the topside and not in a dimmed mode.
• Inspect fuses: Look for a low-voltage or accessory fuse on the MAAX control board and replace if blown with the same rating.
• Check harnesses: Verify that the light harness connectors are fully seated on the control pack and at each LED module.
• Test individual lights: If some lights work and others do not, replace the failed LED assemblies with MAAX-compatible replacements.
• Driver failure: If no lights work and fuses are good, the LED driver circuit on the control board may have failed, requiring board repair or replacement.
