Excellent for a Used Circuit Board
Was impressed that the order was shipped before the end of the day it was ordered and then arrived a day early securely packaged with plenty of padding to prevent damage.

Board was slightly dusty yet not excessively so considering it came from a potentially 22 year old clothes dryer. The board had no signs of scorching, water, etc damage and the dryer now works better than it has in years. Installation only took a few short minutes.

Nice that a 2 year warranty was available at reasonable cost which I took advantage of.

It worked
Instruction video helped with knowing where to look for every panel and plastic component that needs removed, and you'll have to remove almost everything to access the backlight strips. I highly recommend having the suction cups to remove the screen, which I appreciate being offered to me when I checked out because I wasn't thinking about that at the time. Overall it took about a little over an hour to replace this part as someone who does a lot of DIY.
