The MEDS302BS pairs a standard 4.5 cu ft convection oven on top with a 2.8 cu ft steam-capable oven on the bottom, both running 17 modes, for a combined 8,350 watts on a 240/208V, 40A circuit. The upper cavity keeps Thermador’s usual Self Clean cycle and a 12 lb-rated Rotisserie; the lower steam cavity uses a removable water tank rather than a plumbed line.
Because the two cavities use genuinely different cleaning technologies, diagnosing a ‘oven won’t clean’ complaint means first confirming which cavity the customer means – a self-clean door-lock problem on top is a different repair path than a water-tank or steam-generator issue on the bottom.
