A:Answer Hi Jeff,
I am happy to help. The replacement model is PEM31SFS. You will want to purchase the new trim kit with the new model, as the old one cannot be used. This requires the use of the Optional Hanging Kit #JXA019K. This kit is purchased separately and includes the necessary hardware, including the bolts, to hang the microwave. Please contact our Parts Center at 1-877-959-8688, Mon–Fri 8am–8pm, Sat 8:30am–5pm ET. We hope this helps! Thanks for checking with us!
