The DO30CM/B pairs Wolf’s M Series double-oven control with a black-glass, handleless front — two independently heated cavities, a shared seven-inch touch display, and a four-digit problem log that records what the control’s self-checks caught. That log is worth asking about specifically: even if a code is not showing anymore by the time we arrive, the history it kept often confirms exactly which part triggered it.
Self-clean is the cycle that most often turns a marginal sensor or relay into an outright failure, and on a double oven it can lock either door independently depending on which cavity ran the cycle. A convection fan that has gone silent in one oven while the other runs normally is worth describing precisely, since it usually narrows the repair to that single cavity.
