Unit runs but interior light (if equipped) does not turn on.

Safety first: Unplug before accessing the light assembly.

• Check settings: Some models allow turning the light on/off via a button; ensure it is enabled.
• Inspect light module: Access the light cover inside the cavity and check for visible damage.
• Check wiring: From inside the housing, verify the light connector is firmly attached to the PCB.
• Replace light module: If the LED/bulb is faulty, replace the light assembly with a Crux-compatible part. If the driver on the PCB is bad, the main control PCB may need replacement.
