GE MODEL #AKZ10ANT window a/c. Brand new, daylight coming through top of a/c where cool air comes into room. We see the white styrofoam inside wall of a/c...all our other window a/c's are lined with dark...
They have changed thier manufacturing proccess, so it is not uncommon to see the styrofoam. As far as the light shining thru, you might want to chack and see if you have the vent setting in the open position. If it is in the open position, the square flap will be open, and depending on the model and design, you will be able to see light. The vents purpose is to let fresh air in the home, when the A/C is running, but it is not automatic, so the vent flap will stay open, till you close or turn off, the vent setting.
I hope this helps, please rate me, and contact me back with any questions.
