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

Replace bulb: Remove the light cover inside the drum and replace the bulb with the correct type and wattage specified by Haier.
Test door switch: If the new bulb does not light, test the door switch for continuity when open/closed. Replace if faulty.
Inspect wiring: Check the light socket wiring for loose connections or damage.
Control board: On LED-lit models, if the LED and wiring are good, the control board may not be powering the light and may need replacement.
