Can I repair my Regal Breadmaker #K6745S?

I have a Regal Kitchen Pro Collection Breadmaker, model #K6745S. During a baking cycle, the machine shut down. There was no noise or "burning motor" smell, but since it shut down, it will not even beep and flash when it is plugged in. There is no response at all when it is plugged in, now. Is this something that can be fixed? A fuse that needs replaced, or perhaps a replacement part? I spoke with the company's service department, and they no longer sell or service bread machines. I appreciate any information you may have on how I might fix or obtain necessary replacement parts.
Thank you.
