Aaron B S Hamilton , MA October 28, 2019 Worn out timer I watched the really helpful videos on this site. Unscrewed the chassis, swapped the timer, swapped the control knob - BAM! All set. I wish I knew the new control knob came with its own clip instead of buying a second one. Oh well. This was a lot cheaper than paying a repairman. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
