Product review (5 stars): Just what the doctor ordered:  A brain transplant for the washing machine.
My GLTF2940FS2 washing machine decided to stop working after 5 years.  It kept beeping and displaying "E90" (E-nine-zero, and no that code was not listed in the stupid manual inside the washing machine).  Not only did it keep beeping and showing E90 on the little display, the washer didn't work.

The product provided no installation instructions to bore you with,  so I had to figure out that I had to take the little light guides (numeric and buttons) from the old control board box and put in the new one.
