F11 error code continues to show up and beeps

Error code F11 keeps coming up and beeps, unplugged range and let it sit 2 times for 5 minutes. Re power unit and its fine for about 10-15 mins then happens again . I read and it says it probably needs a EOC , Is this the F20 controller board that you guys offer? The AP4433328 (316557217) thanks.
