The dryer had been beeping for months, even when it was not drying. Then cycles began to fail to complete. Eventually only the Delicate cycle would dry clothes. Replacing the control board fixed it all. I had to remove parts from the old control board and put them in the new one. The cycle selector knob was a little tough to get out - I had to pry it with the screwdriver. I also put the Start button into the new board upside down the first time. If not for that the repair would have been less than thirty minutes.
