Safety first: Unplug the dryer before replacing the light.

Replace bulb/LED: Remove the light cover inside the drum and replace the bulb or LED module with a compatible Hisense part.
Check door switch: If the light still does not work, test the door switch as it controls the light circuit.
Inspect wiring: Ensure the light socket wiring is secure.
If the dryer uses an LED driven by the PCB and the LED and switch are good, the PCB light driver may be faulty and require board replacement.

Dryer interior light does not work when the door is opened, but the dryer otherwise operates normally.
