The control knob broke off the timer control switch on my GE clothes dryer and we had to use a pliers to operate the unit until I was able to get a replacement knob. By the time I located a replacement knob the shaft on the control switch was worn down too much to accommodate the new knob so I had to replace the whole switch. The entire replacement took less than ten minutes. After disconnecting the power (pulling the plug) I removed the back plate (six Philip's head screws) and snapped a photo of the wires connected to the control switch just in case I lost track of which wire went where. I then removed the original switch from its mount by raising the release tab and turning it counter clockwise until it popped off. I then moved the wires one at a time from the old switch to the new one. I had to use a needle nose pliers to get each wire off of the original switch because I couldn't get a grip with my fat fingers. Once the wires were all moved I popped the new switch into place with a clockwise rotation, replaced the back panel and pushed the new knob onto the switch shaft (it just presses into place once you line it up correctly) I think t took me longer to type this than it did to complete the repair.
