The MDD3050PM/S/P is the 30-inch drop-down door microwave in this styling family. The MDD designation is what separates it from the MD drawer models: the door drops forward on bottom hinges, so the interlock switches sit around the door frame rather than in a drawer slide. The 30-inch cut-out gives it the larger of the two cavity sizes Wolf offers in this format.
If the MDD3050PM/S/P runs, lights and turns its fan but the food comes out cold, the control side is fine and the high-voltage side is not. That is a magnetron or high-voltage component diagnosis, and it belongs to a technician because of the stored charge in that circuit. The 50 in the number places it in the later M Series generation, and its trim and door hardware follow that generation rather than the earlier M Series parts.
If you are working out exactly which unit you have, the number spells it out: MDD for the drop-down door Microwave, 30 for the cabinet width in inches, P for Professional trim, M for the M Series, 50 for the later generation of that series and S/P for a stainless front with Professional handles.
