John K Pasadena , MD August 26, 2016 Appliance: General Electric General Electric GTDX100EM1WW Ge Dryer Gtdx100em1ww / : The dryer timer was getting tight to turn and it forced the knob to break where it attached to the timer. How to replace Knob Clip. I removed the broken knob by pulling straight out and threw it in the trash. I removed screws along the rear and top of the backsplash. Tilted it forward and removed the timer. You must be careful because the backsplash is made of plastic. The old timer had 2 screws holding a wiring harness that was not needed and was thrown in the trash too. The new timer had a small hole that matched another hole in the backsplash. I used the old screw to help hold the new timer in place. I changed the wires, one at a time from the old timer to the new timer. I tilted the backsplash back and installed the screws on the rear top of backsplash. Plugged the new knob on the front by pushing it on the shaft. I plugged the electric plug in and tested it out. Perfect DIY job. Saving money for the things I can't find time to do. Every little bit helps. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
