Gail R Arvada , CO August 24, 2015 Appliance: General Electric Washer WJRR4170G1WW Ge Washer Wjrr4170g1ww: Washer timer know would not turn washer on while dial would. How to replace Control Knob Assembly. Ordered new timer, dial and control knob assembly. After unplugging machine I removed the knobs from the control consul. Removed three screws holding consul face plate from rear of machine. Moved faceplate forward to gain access to electronic components. Timer is located on right with one hold down screw which I removed. Lifting timer from mount location I removed wiring harness. Installed harness on new times and inserted into hole for knob. It would be helpful if front was market on timer. Installed screw and reinstalled consul face with three screws. Installed all control knobs except timer. Installed dial with arrow up and pushed control knob into place. Pulled control knob out and pushed in to set timer to desired cycle. Turned on and the washer worked. 10 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
