Hello, I had a service tech tell me I would need to replacemain board assembly, thereis no power being sent to valve. Your parts list shows it called asmodule control asm part# AP3794574 is this the correct part? and do I need to replace any of the computer tapes also part @9101? The service guy told me around 400-500 dollars and your part is under 100 dollars. I have dismanteled part just not sure if this part will resolve the problem and is it necessary to replace the other computer tapes they appear to be in good shape? Do they have anything to do with problem? Thank you for your help, just want to be sure before I order part. Jim
