I Have A Ge Dual Wall Oven Model Jtp48sof1ss. We Have Had Several Power On/offs With A Faulty Transformer In Our Area. Since Restarting The Power, We Keep Getting An F7 Flashing Code. I Was Able To Disconnect The Touchpad Ribbon And Restart For A Few Weeks, Now It Does Nothing But Read F7. Sometimes I Can Get The Broil Only To Come On. I Found Some Part Numbers On The Controller Such As Wb27t10428. Is That The Part I Need? How Do I Order This From You?
