If it's available, that is! I know most appliance repair techs are not going to go through this, but there are probably two components on the computer control that I can not buy off the shelf. The SMPS transformer and the cpu with masked firmware. The washingmachine had a third, the 3phase driver for the big motor, which is off the market now.

I figured the simplest dryers just had a "one heater, or two in series, or two in parallel" switch and a melting safety.
