This is the first time i ever fixed a dryer and it was easy. Our timer knob broke several months ago and instead of replacing it, i would just use a pair of plyers to turn it to the cycles. This worked great for three or four months untill one day i broke the stem off the timer with the plyers. At this point i was wishing i would have replaced that $10.00 knob but oh well can't change that now. So i typed the model # + timer into the computer and found what i needed on the G.E. site. I wrote the price down and checked the same parts on amazon(the timer shaft and knob). On amazon i found the same parts for one hundred dollars less. Really glad i double checked. The parts arrived before they were promised(Took like three days to get here.). I now unplugged the dryer and unscrewed the controll panel. From there i put the new timer shaft in and unhooked the wires one by one and hooked them up to the new timer as i went so that way i would hook them up correctly. This is important do not unhook the wires before hand unless your a rocket scientist. Then I screwed the controll panel on and pushed on the new Knob. Plugged it back in and presto. Dryer ran like new.
