Early last year (Jan. 2009) the oven temp Touch Pads stopped working. Each individual numbered touch pad went out one-at-a-time starting with"0" and systematically shutting down one at a time from right to left on the bottom row of numbers the top row still works (1,2,3,4,5) onlly the bottom row has stopped working (6,7,8,9,0).

My question is must I replace the entire TOUCH PAD and the ELECTRiCAL CIRCUIT or is the problem tied to only one of these parts?

Any ideas will help......thanks.:)
