This timer had been used a few times when it developed erratic operation. We replaced it, and then did a thorough analysis for the cause of the failure. We found a bad bearing hole in the frame that was caused by a defective gear. First such problem we have ever seen. That side of the frame has been replaced and a new gear installed. The timer now runs like new. This is the latest design version with the heavier DT wire and deep thread scroll. You may want to get a winder tool as this model has no ears on the scroll.
