Hi Mary, that error is a door locking error. You'll want to trip the circuit breaker for 30 seconds and power back on to clear the error. ^Rosi

Thanks for the question. While Samsung Ranges are designed to maintain a relatively consistent temperature, it's normal to have some fluctuation within a few degrees as the heating elements cycle on and off. If yours is fluctuating significantly, however, I would suggest calling 888-BEST BUY or 800-SAMSUNG to speak with an agent who can help determine whether service is necessary.
