Peter R Mt. Pleasant , SC December 22, 2014 Oven temperature erratic in both ovens After testing the sensors, which both proved to be working properly, I replaced the control board which took no more than about 15 minutes to do. All connections were clearly marked and the replacement was an exact match. The oven is now working properly. Just used a #2 Philips screw driver. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
