Robert N Seneca , KS October 25, 2024 Appliance: General Electric Dryer GTD42EASJ2WW Ge Dryer Gtd42easj2ww: Dryer would not turn when the start button was pressed. How to replace Dryer Timer Knob. I did a voltage test on the wires to the start button. There was no power to the start button. Then checked power to the timer switch and had 120 volts to the timer. I then found that the knob was spinning on the timer shaft which allowed the timer to remain in the off position. I turned the timer shaft with a pliers and everything worked. Conclusion I ordered a new timer and timer knob. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
