Darwin M Guthrie Ctr , IA January 30, 2026 On/off speed control switch would not work right away might be a couple of minutes before it would start sliding switch rapidly back and forth might get it to start I installed a new speed control assembly. Took about ten minutes. Watched a you tube video on how to do it. Wife was very happy; it was still my fault for not doing it sooner. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
