Fixed broken knobs and switch

First, I unplugged the dryer. Then, I removed the back panel from the controls section (6 screws), disconnected the old switch and reconnected the new switch. Positioning the switch in the control panel took some figuring out, but once I realized that the switch slots into place, and then gets locked in by turning 1/8 of a turn, it worked fine.

Replacing the knobs was a cinch, just popped them in place. Now the controls are like new again.

Frigidaire controls are really junk, though. I won't be surprised if I have to do this repair again in two years.
