Ric C Seattle , WA February 27, 2016 Appliance: Kenmore Electric Range 79045062401 Kenmore Range 79045062401: Controller. How to replace Controller. After contacting Appliance Parts Pros(APP) they narrowed it down to 2 possibilities, I watched the repair video on replacing the controller and it went pretty fast(about 10 minutes). My controller was in front so I didn't have to unscrew a lot of screws. This was my first time working on the oven and It was easier than I thought. I recommend others contact APP and talk to the pros on first narrowing down the problem, watching repair video, and than save yourself a lot of money by doing it yourself. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
