A:Answer We bought the trim kit for GE PEM21SF. You have to make sure the trim kit matches your model. The previous owner seemed to make a home made trim kit using SS grills. Cheaper models did not fit into the hole in the cabinet. Whichever trim you buy, take great care while mounting since the front face will probably be plastic with a SS finish. With plastic you have one chance to mount it properly. If you botch the mount, you will have to buy a new kit, so it won't look bad.
