The MB30WP is Thermador’s 30-inch Professional-collection built-in microwave, identified on its own product page as a drop-down door design with a 1.6 cu. ft. cavity and 1750-watt output on a standard 120V/15A circuit. It uses the same CookSmart auto-program set and Home Connect Wi-Fi platform as the rest of Thermador’s current built-in microwave line, and it requires a cutout of roughly 19-1/4″ high by 28-1/2″ wide by 19-1/4″ deep.
Most service calls on this generation of Thermador built-in microwaves trace back to the door mechanism, the touch control panel, or the turntable drive rather than the magnetron itself. A drop-down door that doesn’t latch flush can leave the interlock switch unsatisfied, and a control panel exposed to steam or condensation is a documented cause of keypad problems. When a numeric error code appears, Thermador’s own support guidance is to note the exact code, cut power at the breaker, and report that code when requesting service.

Most Common Issues on This Model
Drop-down door hinge wear or misalignment can keep the door switch from sensing a full seal, so the unit won't start
Touch/keypad controls can stop responding after condensation gets into the control panel
Turntable motor, coupler, or roller-ring wear causes uneven heating or a turntable that won't turn
