Mark S for Model Number SMH9207ST I have this microwave, bought new, installed in NEW kitchen after move to new house. NEVER used prior to install in new house. program heating, runs a few seconds, then EVERYTHING DIES! no sound, no display, nothing. play with door will sometime reset it, not always. was told possible key pad or some PCB. is pcb (ML9P-0) in controller area responsible or is it the one in door? Will replacing door fix problem do you think???????
