Safety first: Disconnect power before changing bulbs or opening the housing.

Step-by-step:

Replace bulb: If your Hormann operator uses a replaceable bulb, install a new bulb of the correct wattage and type as specified in the manual.
LED module: For integrated LED lighting, inspect the LED board for damage. If the LEDs are dark, the module may need replacement.
Check settings: Some models allow disabling the courtesy light via programming. Ensure it is enabled.
If still not working: The light relay or driver on the control board may be defective, requiring board replacement.
