Hi my name isXXXXX have been an appliance repair tech since 1992.With what you have done already, the only issue is the relay on the board is not making up. If you have lights you have power, the thermo fuses are ok because you have lights, and no error codes, indicate a bad relay on the main control pcb. Part# DC92-00162BYou can gain access by removing the rear top screws to the top. slide top off to rear. And then you can gain access to the screws for the control board.

Thanks for the help. Part is ordered, but will not get here until next week. If it fixes the problem I will let you know.
Part come this morning. I installed. Same problem I had before I installed the new part. What is plan "B"?
