Andrew S South Royalton , VT July 25, 2016 Appliance: Model 796.40272900 Machine turns itself off randomly seconds after turning it on Replaced the "PCB Assembly, Main" and it works great now. I got instructions by searching online. The replacement was pretty easy for an average DIYer. The hardest part was disconnecting the cables from the initial circuit board. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
