A:AnswerSusan your current model MMV5201dBoo uses a filler kit UXA3036BDB 36" Microwave Filler Kit
If you have the filler kit you can simple find a model of your choice that has a filler kit or purchase
a unit that is an exact fit. The model MMV4205FZ does not have a filler kit.
Please see this document for your current models dimensions and installation. Page three will show your
dimensions and cut out to work with. Hope this helps. Happy shopping.
