Replaced control board. Ordered twice. First one ordered from another company. Board did not include a timer knob shaft. I tried using shaft from old board, but mistakenly thought the shaft was not removable. I sent board back and ordered from this company due to videos and tips provided here. I read a tip here stating that timer shaft should be included, but if it's not, the old one can be used. When new board arrived, it also did not include timer shaft. I turned the old control board shaft and lightly pulled, and on about the third position, it slipped right out. There's a notch that must be aligned. Afer all of that, repair was very quick.
