My front load GE profile dryer runs good, but the lights on the user interface do not light up. Although, the inner digital display lights up and shows what setting I'm on, but all the other lights are out (power button, lights around dial, selection lights, etc) Would I need a new main power board assembly WE4M454, or do I need the interface control board assembly we4m418? It doesn't affect the dryer functionality, but I would like it to light up again. I was thinking maybe the lamp relay went bad on the main power board. What do you think? Thanks.
