In the lightwave oven range, there is only one lamp in the left side of the top.
The lamp turns on automatically when you start cooking or open the door.
If the lamp turns on when you open the door, it is not a lamp failure.
The bright light turning on and off during cooking is a phenomenon in which the oven heater (halogen heater or hardwood charcoal heater), not the lamp, is turning on and off in order to properly control the temperature inside the oven.
Depending on the product, for a model with the [Lamp] button, if you wish to light the inside more brightly during cooking, press the [Lamp] button to operate the oven heater for 5 seconds to brighten the oven.
