Safety first: Unplug the dryer before replacing the light or accessing wiring.

Steps to check and fix:

Replace bulb/LED module: Access the drum light cover inside the drum. Replace the bulb or LED module with the correct type.
Check door switch: Ensure the door switch operates correctly and sends a signal when the door is opened.
Inspect wiring: Check the harness from the control board to the light for continuity.
Control board: If the light still does not work with a good bulb and wiring, the control board light driver may be faulty.

Dryer runs but there is no drum light (on models with internal light)
