Built as a 30-inch built-in microwave with a bottom-hinged door, the MDD30TM/S/TH sits flush in cabinetry in Transitional trim with tubular handles. Because the door opens downward into the working space in front of it, a hinge that has lost its damping is noticeable long before it becomes a fault. The 30-inch cut-out gives it the larger of the two cavity sizes Wolf offers in this format.
On the MDD30TM/S/TH, a cycle that will not start is more often the door interlock than the magnetron. The control checks a set of switches around the door frame before it will energise anything, and a door that has dropped slightly on its hinges can stop closing squarely enough to satisfy them. This one belongs to the M Series styling family, so its door, handle and trim parts are shared with the M Series ovens it is usually installed alongside rather than with the E Series.
The suffix carries more information than people expect: MDD for the drop-down door Microwave, 30 for the cabinet width in inches, T for Transitional trim, M for the M Series and S/TH for a stainless front with Tubular handles.
