Unplugged dryer.
Removed front control knob and removed two bolts behind it using 1/4" nutdriver.
Unscrewed three phillips screws along top of control panel.
Using slight shaking motion to release tabs, removed control panel from top/back of dryer and pulled forward.
Using needle-nose pliers as necessary, removed electrical lines from old timer and inserted them onto corresponding tabs on new timer. These are color-coded, but I found it just as easy to move each line from one timer to the other in order as I removed them.
Used nutdriver to attach new timer to control panel.
Reattached control panel to top/back of dryer and reassembled housing using the phillips screws. Reattached control knob.
Plugged in dryer.
Took me 35 minutes -- I am a 70-year old woman who has never done a repair like this before!
