How to Troubleshoot & Replace Frigidaire AP4433205 / 316419821 Range Touch Pad Overlay

I spoke to a representative at Appliance Parts Pros, gave the error code and model number of my oven. Within minutes the part was identified, order was taken, and the part was delivered via overnight shipping - all at an extremely reasonable price! Replacing the part was rather simple, even for me, a not particularly handy person. 

Upon a brief inspection and troubleshooting of the electronic control board, it seemed that the problem could in fact lie on the board. But, I was not certain though. Nevertheless I want to replace the board. I tried to find one on various sites on the net but found no match until I get to appliance partspros. Live chat with a technician was a plus and, few questions later , she reached to the same conclusion as I. 3 days later I had the board at my door and the stove in full operation. I' very satisfied with an excellent service. 

Placed the overlay on the display after peeling off the original and the problem was solved. 

Bought a new one and had to replace it.
