The light in the upper oven/microwave is REAL dim. Basically just enough light to see that there is "something" in there. It's missing a speed cook to utilize the convection and microwave in conjunction with each other. The assembly... OMG.. was the worst assembled product I have EVER seen. 37 loose screws, 14 stripped out 4 the wrong length, and 6 missing (found 3 in the bottom of the box and 1 INSIDE a panel) unless taking it apart and rebuilding it is part of the "normal" install process.. they NEED MASSIVE changes to quality control.  That being said.. after tightening, and replacing the missing screws (nothing can be done about the stripped ones) it is performing as expected with no noises.
