What trim kit do I get for the PEB7227DLWW

GE® Required 27" Built-In Trim Kit JX7227DLWW will work with your model.

Hi - GE Profile™ Series Microwave Oven PEB7227DLWW is compatible with GE® Required 27" Built-In Trim Kit JX7227DLWW and GE® Required 30" Built-In Trim Kit JX7230DLWW. The only difference between the 27" and 30" trim kit is the trim frame width. If the microwave is installed over a 27" or 30" wall oven, be sure to match the trim kit width to the oven.
