After 2 repair people quoting $1200-$1500 to repair our stove I did some, 15 minutes of research and found the service bulletin which referenced the ESUI board which I purchased at AppliancePartsPros.com for $162.85 including shipping. In the service bulletin were very good instructions on installation. It took me less than 1 hour to make this repair. Granted I am more skilled at such things than the average homeowner, but it really was not that difficult. For some reason the repair folks wanted to replace the entire control board.
