Only the color separates the CIT304TB from the CIT304TM: both carry identical induction electronics and behave the same way. Thermador has replaced the pair with the CIT304BB, so anyone with a black-glass unit like this one is working with an older design that nonetheless follows the logic of today’s induction cooktops.
Our approach on a call is to sort what the cooktop reports from what it is doing. Demo mode, a zone that overheats, or a pan that is not recognized all have documented explanations, and we run through them before opening anything up. A touch panel that goes quiet is checked for moisture and residue first.
Since the model is discontinued, we also verify early on whether the part we have identified is still obtainable. Doing it before the price is written up keeps the estimate honest and avoids a stalled repair.
No. The finish is the only difference. The induction electronics and control behavior are identical, so the same diagnostic steps and, in most cases, the same parts apply to both.
Because the cooktop is discontinued, sourcing can take longer than on a current model. Confirming the part once we have named the problem lets us give you a realistic written price and timeline.
Make sure the pan is induction-compatible, flat, and centered on the zone, and wipe the glass dry. If the zone stays cold with a pan that is known to work, a technician should test it.
