Dina D Polo , IL December 08, 2017 The timer knob would not stay on and the piece that held it was stripped We ordered a new timer and knob here. It took my husband about 15 minutes. The timer was a bit pricey but way cheaper than an apppliance store fee of $90 just to look at it. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
