For your Samsung NE63B8651SS, the C-F2 error code points to a communication problem involving the touch control panel and the oven’s electronic controls.
Since you’ve already replaced the controller board and the same error returned, I would focus on the touchpad/user interface assembly and its wiring connections before replacing another main board.
Here’s what I recommend checking next:
1. Reset the range. Turn off the double-pole breaker for about 5 minutes, then restore power. If C-F2 returns immediately, that suggests an ongoing communication problem rather than a temporary glitch.
2. Inspect the control connections. Turn the breaker off again. Access the control panel and inspect the ribbon cable and wiring harness connecting the touch controls to the main board. Look for loose connectors, bent pins, corrosion, or damaged wiring. Disconnect and carefully reseat the connections.
3. Check the touchpad assembly. Since the touchpad is completely unresponsive, a failed touch control/user interface assembly is a strong possibility. A new main controller won’t correct the problem if the touch panel itself has failed.
4. Verify the replacement board. Make sure the new controller is the correct part for the complete model number, including the revision suffix, and that all connectors are installed in their proper locations.
The fact that the surface burners still work doesn’t rule out a control problem. The cooktop and oven use different control circuits, so the burners can operate normally even when the oven controls have failed.
My recommendation: Don’t purchase another main control board yet. I would inspect the connections first, then concentrate on the touch control/user interface assembly.
One question: When you turn the breaker back on, does the C-F2 code appear immediately, before you press any buttons, or does it appear after the range has been powered on for a while?
That will help narrow down whether we’re dealing with a communication failure at startup or an intermittent control problem.
