Ahhhhhh, so that's how you'll make Maddie leave, cuz of the Microwave, thanks for the tip!
If Remember correctly the microwave breaks if you use it too much so try to not use it too much. I personally only use it when she is in the doorway, because even if she is blocking a task camera you won't get a game over unless you have 3+ task failing so you cna just wait and try to keep that 1 camera task as the only one that fails
