Interior light (if equipped) does not turn on, but unit otherwise works normally.

Safety first: Unplug the appliance.

Lamp/LED module:

• Access the interior light cover and remove it according to the manual.
• For bulb-type lights, replace with the same type and wattage rated for high temperature.
• For LED modules, inspect the connector and wiring; replace the LED module if visibly damaged or open-circuit.

Control board:

• If a new lamp or LED module does not light and wiring is intact, the light driver on the control board may be faulty; replace the main control board if light function is important.
