I removed the three screws that hold the front switch cover to the backing plate. I then slid the front cover to the right and pulled it out and forward. I marked all the wires and removed them. Now the front cover is free. starting from the left i removed the knobs and the switches. The switches have a tab on them and they twist out of their socket. The front cover plate was also broken so I replaced it. In the new front cover plate I installed the switches starting from the right. When I got to the start switch I installed a new switch and knob.I then installed the rest of the knobs. then I installed the wires and put the tabs in their place and slid the cover plate to the left and installed the three screws.I then tested it and it worked great .

Order a new plastic switch holder for the dryer.
