A:AnswerThe compatible Trim Kits for the NN-SD975S Microwave are: for 30" cabinet the Trim Kit model is NN‐TK922SS and for 27" cabinet the Trim Kit model is NN‐TK932SS
A:AnswerHi! The trim kit you mentioned is for a 30" cabinet, which means it will be larger. Please take note that gaps are necessary in order to ensure proper ventilation. -M
A:AnswerWe bought this trim kit and it has gaps all the way around the NN-SN77HS microwave. The trim kit is too big for the microwave, I do not agree that it is compatible.
