The MC30WP is Thermador’s 30-inch Professional-collection speed oven – filed by Thermador under its own “Speed Ovens” product category, distinct from its plain built-in microwaves, but grouped by this site under microwave-repair following the precedent set by the existing MC30WS entry. Thermador’s product page confirms a 1.6 cu. ft. cavity and a 3840-watt, 240V/16A electrical rating, dramatically higher than a standalone microwave because the unit also drives a convection heating element and fan. It offers 36 CookSmart auto-programs and three combination (microwave-plus-convection) cooking modes.
Because a speed oven layers a convection system on top of a microwave, it has one extra failure mode standalone microwaves don’t: a bad heating element or convection fan can leave the unit microwaving food but no longer browning or crisping it, even though the display shows no problem. Door-switch, keypad-condensation, and control-board issues otherwise track the same patterns documented across Thermador’s microwave and speed-oven support pages.
Key Features
- 30-inch Professional-collection speed oven combining microwave and convection heat, with stainless steel control knobs
- 1.6 cu. ft. cavity, rated 3840 watts on a 240V/16A circuit (far higher than a standalone microwave, reflecting the added convection element)
- 36 CookSmart auto-programs, three combi (microwave+convection) modes, and Home Connect Wi-Fi
Most Common Issues on This Model
Convection heating element or fan failure can leave the unit working in microwave-only mode
Door hinge/seal wear can trip the same interlock and error code behavior as Thermador's standalone microwaves
Touch controls can stop responding after condensation exposure, consistent with the E11 error documented across the line
