After the moving-in upgrade in 2025 I have a functioning Frigidaire Professional built-in stainless steel convection microwave oven.
The Frigidaire Professional 30" Drop-Down Door Microwave features Convection Bake Technology. You can prepare grilled favorites like steaks or sandwiches right inside your microwave with Grill/Broil mode. Plus, it has features like Combi Cook, Sensor Cook, Sensor Reheat and Keep Warm offer time savings so that you can put delicious meals on the table without all the extra effort.
I also have a KitchenAid 30" built-in convection oven that creates a set of cooking wall units. The price is $600.
