A:Answer Hello - Thank you for your inquiry and your interest in the innovative Ultrafast Combo unit! This remarkable appliance features an industry-first UltraFresh System with Microban® Antimicrobial Technology, ensuring a consistently fresh and clean interior load after load, effectively preventing odors and mold concerns. If you run a wash-only cycle, we recommend leaving the door propped open briefly to facilitate interior drying, although wiping down the gasket periodically is also advisable. However, when running a wash and dry cycle, there's no need to leave the door open, as the drying phase will effectively dry out the interior. Rest assured, the light on the door will turn off after a few moments when not in use. If you have any further questions or require additional assistance, please feel free to reach out. -Kacie@GEAppliances
