Lights flicker and then shut off

My GE refrigerator model GFE28HMHFES LED lights work as soon as you open the door, then start to flicker, and then go out. I have already replaced all of the LED lights but it is still flickering and then shutting off. The fridge is roughly 8 years old. I did notice if you slam the bottom freezer, the lights will flick back on in the fridge, and then back off.
