Product review (5 stars): IT WORKS
Horray, It works perfectly.  If you can unscrew a screw, and plug something in, you can do this.  I found the way to diagnose the problem on the internet. Then, I ordered this part as the recommended solution.  I was very nervous, afraid that it would be complicated, but I  carefully unscrewed the right side, took the old board out, and put the new board in, then the same on the left.  It worked immediately. I am thrilled that I didn't pay a service call fee of $80 or more, and pay 4 times as much on the part to do this 10 minute job.
