Product review (5 stars): Giving it 5 stars because it works fine since installing yesterday
This was the exact replacement for my Frigidaire FFEF3050LS. The Amazon part search resource couldn't guarantee this was the right replacement part, but I found the 316557115 number on a label on top of my burned out control board (it had actually generated flames out the back of the range when it failed). The only way to see the number is to unscrew the board and pull it out. Giving it 5 stars because it works fine since installing yesterday. By the way, I didn't need to buy a new plastic overlay. Using caution, I removed the old one by running a razor blade all the way around between it and the old control board. There was still enough adhesive to stick to the new control board, and so it maintains the original appearance.
