A:Answer Hi there, thanks for reaching out to us and for your patience. While we are sorry to hear that your current microwave is failing, we are so glad to hear that it has served you well for so long. We truly appreciate your interest in this beautiful sensor microwave and are happy to offer you guidance in a replacement! We offer a variety of countertop microwaves, but only select models can be installed in a cabinet for a built-in look using a trim kit. This specific model is a countertop only model and we apologize for any disappointment this may cause. - However, we would recommend the PEB7227DLBB model that offers a similar appearance and sensor cooking features and is built-in compatible! Because trim kits are model specific, the JX7227DLBB 27" trim kit will be required for its installation. It is important to only use the trim kit designed for that model so that the trim kit fits the microwave and provides the proper air flow that it needs. You can see additional details of this microwave and the required cutout space for installation here: https://files.bbystatic.com/6Y3CcukvUw3Q%2BvRvdclByw%3D%3D/85DBFE08-EFD7-474C-A72C-81A9C080C7FD.pdf. - We sincerely hope that this recommendation is helpful and would be happy to answer any additional questions you may have about the many features that it offers. Thanks for being such a loyal member of the GE Appliances family! -Eliza@GEA
