We have a Samsung oven model NX58F5500SB. (Model code NX58F5500SB/AA.)

For months, the panel has been flaky -- being unresponsive, showing SE code, etc. We have usually been able to resolve this by resetting the oven -- unplugging the appliance, waiting, and then restoring power.

However, this kludge no longer works; the oven no longer resets when we cycle power.

I guess I need to replace the control board. Which part do I need to order? Thank you.
