What should I do if only one of interior lamps is on during cooking?
(Only for lightwave oven)
Symptom
1. Only one of interior lamps turns on during cooking.
Cause
1. Oven lamp is located at an upper hole at the top left corner of a cooking room.
It turns on when cooking starts or a door is open.
2. A charcoal heater is installed at a long upper hole on the right side of the ceiling.
As the heater works on a different algorithm depending on a menu, it is not always turned on.
Brightness can also differ by menu due to a inverter control.
