So my double oven (RBD275PDB14) died a while back (no error codes) and this forum suggested I replace the control panel assembly. I replaced the entire assembly, sister board, thermal fuse, and keypad. Nothing worked, then mysteriously one day it started working. It worked a while and then again went dead...again no error codes. A few days later it started working again and worked for a few months. A couple days ago we went to bed and it worked, we got up and it was dead. Same characteristics panel dead, beeps when buttons pushed, light turns on when you open the oven doors. today my wife texted me that the oven beeped and showed E6 F2 error codes....Need help please. Thanks!
