Hello there.
Let me give you a hand, let's reset the unit. Cycle the power to the range, by turning the circuit breaker off, wait 30 seconds, and then turn it back on. If after doing this, the code returns or the unit still does not work. Please get in contact with us via 1-FacebookMessenger:http://m.me/samsungsupport
