My microwave finally died & I can't find anything to replace it size wise. It is a Sharp R-312. I did see on here that a Panasonic SSN667 fits perfectly but I can't find one. Any other ideas? Thanks
Getting the old one repaired may be a good alternate. There is a high voltage fuse and a capacitor inside that are easy to replace. Find a local handyman who works on microwaves. I have repaired several of them.
