I removed the two Phillips head screws in the front of the control panel, this allowed the unit to lay flat forward so I did not need to pull the dryer from the wall. This allowed me to gain access to the screws that held on the panel, after removing the panel I removed the timer and laid the new timer beside it and transferred the wires to the new timer. Then I replaced everything in the reverse order. Be sure to unplug the dryer first, and I also took the time to clean lint from the control panel area while I was their.
