Microwave light does not turn on, but cooking works normally

Safety: Unplug the microwave before replacing the lamp. Glass can be hot and fragile.

• 1. Access lamp: On many OK models, the lamp is accessible by removing the top grille and a small cover, or from the rear.
• 2. Replace bulb: Install a new microwave-rated lamp of the same type and wattage.
• 3. Inspect socket: Check for heat damage or loose contacts. Replace the socket if burnt.
• 4. If a new bulb does not light: The lamp relay or wiring may be faulty, requiring control PCB or harness repair.
