Wow 10 years on a VS motor! That's fantastic for any motor. My guess is that repair part costs may not make any sense for a motor this old. But just in case see below.
When I got mine a few years ago I did a lot of research. They do have parts lists that includes a replacement user interface panel for the 2.70 but not the 1.65. However they do offer a remote panel that may work fine as well as a digital control module for the 1.65 and .85. They may have the part for the 1.65 also and I would call them for this. Here's the contact info I had:
Regal Beloit America, Inc.
1325 Heil Quaker Blvd.
LaVergne, TN 37086
Customer Service: 866-887-521
I've also attached the somewhat limited parts and accessories brochure.
I hope this is helpful.
