Jason R Utica , KY January 26, 2015 The heat setting would not shut off When I pulled the cover off, I found that one of the components on the PC board had overheated to the point of charring. I pulled the old board, installed the new one and the unit started working normally. Prior to pulling the board, I took several pictures from different angles so I would have a record of which wires were plugged in to which connector. The biggest problem I had was working with the small wires in tight spaces with my big fingers while trying not to break something else. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
