A:Answer I'm happy to help with this, Jeff! Based on what you've described, it is most likely the microwave is in "demo mode" which allows the buttons to function, but prevents the microwave from heating. But not to worry, this link (https://bit.ly/3CMnD6b) can walk you through how to turn off demo mode, as well as what else to check if that does not resolve the issue. ^Jecca
