A:Answer Our GE, GE Profile, Cafe, and Monogram Advantium & Microwave Ovens (built-in and built-in capable) are not required to be cross-listed with specific wall ovens or warming drawers. They are compatible over most 27” and 30” wall ovens (including French-Door models) and warming drawers. Refer to the installation instructions of both products to determine cabinet cut-out requirements. Lauren@GEAppliances
