The POM301W is the Professional Collection sibling of the Masterpiece MEM301WS: a 4.5 cu ft, 13-mode convection oven on top and a dedicated 4.7 cu ft microwave-only cavity on the bottom, drawing a combined 10,200 watts on a 15A circuit per Thermador’s spec sheet. As with its Masterpiece counterpart, the lower cavity has no bake, roast, or convection modes of its own – microwave only.
That split is the key diagnostic fact: a no-heat complaint in the lower cavity is a microwave-system issue (magnetron, turntable motor, high-voltage diode), while the same complaint in the upper cavity points to the convection elements, fan motor, or control board instead.
